Program board contains two CPLDs. One is presumably similar to the [[PCM]] chip, while the other appears to be used for protection.

Some [[Power Spikes II]] MVS cartridges were converted to Puzzle Bobble by SNK by doing the following:
* Replaced the Power Spikes II P1 ROM by the Puzzle Bobble "d96-07" P1 ROM in the EP1 spot.
* Replaced the Power Spikes II V3 ROM by the Puzzle Bobble "d96-01" V3 ROM, also added the "d96-05" V4 ROM.
* Replaced the Power Spikes II C5 and C6 ROMs by the Puzzle Bobble "d96-02" C5 ROM and "d96-03" C6 ROM.
* Replaced the Power Spikes II S1 ROM by the Puzzle Bobble "d96-04" S1 ROM.
* Replaced the Power Spikes II M1 ROM by the Puzzle Bobble "d96-06" M1 ROM.

To probably save on manual labor, the unused Power Spikes II V1, V2, C1, C2, C3 and C4 ROMs were not removed.

Freem: update link to YY-CHR, convert old link to Wayback Machine

__NOTOC__
[[File:yychr.png|400px|thumb|right|Original C++ version of YY-CHR.]]
[[YY-CHR]] is a tile editor which can handle NeoGeo [[sprites|sprite]] and [[fix layer|fix]] tiles with the help of converters like [[NGGTool]]. Two versions of the program exist, the original in C++, and a new version (YY-CHR.NET) using the .NET framework.

==Features==
* 128*128 editing canvas
* Paste from bitmap
* Flip/rotate/shift in 5 different tile sizes
* Color replace
* Zone cut/copy/paste

==Versions==
Both versions are similar, though the .NET version supports a few more formats out of the box.

===YY-CHR (C++)===
The original version of the program runs better in WINE and has a selection tool not found in the .NET version.

===YY-CHR.NET===
The .NET version of the program runs better in Windows 7 compared to the C++ version. A third-party plugin named "NeoFixFormat" ([[File:NeoFixFormat_1.0.zip]]) is available for opening fix tiles without requiring conversion.

Z80

2017-05-24T15:50:43Z

Freem: remove reference to "tracker music" since ADK driver uses raw MML

[[File:cd2_z80.jpg|right|thumb|Z80 in a surface mount package, as found in the MVS and CD hardware.]]

The Z80 is an 8-bit little-endian CPU designed by Zilog.

All NeoGeo systems use it to handle sound and music playback. It runs at [[clock|4MHz]] and only has access to the {{Chipname|YM2610}}, {{Chipname|M1 ROM}} or [[Z80 file]]s, and its [[Z80 RAM|own RAM]].

See [[68k/Z80 communication]].

Since it doesn't share a RAM area with the {{Chipname|68k}} CPU like on the Sega Genesis, it can't be used efficiently to perform gameplay-related tasks.

See [[Z80 memory map]] and [[Z80 port map]].

|}

Note that the [[M1 ROM|Z80 ROM]] [[Z80 bankswitching|bank selection]] is done by '''reading''' ports.

SNK used an obscure feature of the Z80: when accessing ports, the entire address bus is set, not only the lower 8 bits.

The banks can then be chosen by putting the bank number in B, the port number in C and doing IN A,(C).
This is handled by {{Chipname|NEO-ZMC}} in cartridges.

Some [[sound driver]]s use port $C0 (and others ?) in their code. Since only SDA2 and SDA3 are used for port decoding, port $C0 maps to a mirror of port $00. It's believed to be a remnant of some development tool.

__NOTOC__
:''Mainspace pages of interest: [[Sound driver]], [[Sound drivers list]], [[YM2610]], [[YM2610 registers]], [[Z80/YM2610 interface]], [[68k/Z80 communication]]''

==Driver Overview==
The primary source of sound drivers was SNK. Most third parties stuck to using the MAKOTO series (and the Mr.NORIC driver on CD). ADK created their own in-house sound driver as well.

===SNK===
SNK had multiple sound drivers, starting with one labeled "Mr.Pac", and ending with "Sound Driver(ROM)Ver 1.9".

====Mr.Pac====
:''More Information: [[User:Freem/Sound Drivers/Mr.Pac]]''
The original sound driver.

* '''"Ver 1.5b by Mr.Pac h Ber.02/01/08"''' – Used in the BIOS M1 driver, as well as the first four released games (NAM-1975, Baseball Stars Professional, Top Player's Golf, and Mahjong Kyoretsuden).
** Date: Heisei 2 (1990) January 8th
* '''"Ver 2.0 by Mr.Pac h Ber.02/02/14"''' – Used in games from 1990 (starting with Riding Hero) to 1998 (Blazing Star).
** Date: Heisei 2 (1990) February 14th

====MAKOTO====
:''More Information: [[User:Freem/Sound Drivers/MAKOTO]]''
MAKOTO appears to be an evolution of the Mr.Pac driver, as its first appearance is marked "Ver 2.0a".

* '''"Ver 2.0a by MAKOTO.03/04/05 to SK"''' – Used in games from 1992 (starting with Mutation Nation) to 1995 (Goal! Goal! Goal!).
** Date: Heisei 3 (1991) April 5th
* '''"[[MAKOTO V3 driver|Ver 3.0 by MAKOTO.04/03/10 to SK]]"''' - Used in games from 1992 (starting with King of the Monsters 2) to 2001 (Jockey Grandprix, encrypted). Also found in the Neo-Geo CDZ BIOS.
** Date: Heisei 4 (1992) March 10th
* '''"Ver 3.2 by MAKOTO.97/06/01 to SK"''' – Found in the Samurai Spirits RPG Neo-Geo CD game.
* '''"Ver 8.3 by MAKOTO.98/05/07 to SK"''' – Found in later games, from 1998 (Neo Geo Cup '98) to 1999 (Prehistoric Isle 2).

====Mr.Noric====
:''More Information: [[User:Freem/Sound Drivers/Mr.Noric]]''
* '''"Ver 3.0 by Mr.Noric.1993/11/10 14:00"''' – Sound driver found in most CD games. Also found in the Neo-Geo CD (front and top loader) BIOS.

====Sound Driver (1995-2000)====
:''More Information: [[User:Freem/Sound Drivers/To SNK]]''

* '''"Sound Driver Ver 0.0 95/08/11 To SNK"''' – Found in Kizuna Encounter/Fu'un Super Tag Battle (1996).

User:Freem/Debug menus

2016-09-10T16:04:45Z

Freem: /* Todo */ add link to ryou's writeup on the neo bomberman debugging stuff

Many Neo-Geo games have debug menus and development tools lurking in their code, waiting to be discovered. Some are as easy as messing with the [[Debug DIPs]], while others require more work.

==Twinkle Star Sprites==
If ROM address 0x0000FF (0x1000FE in an un-byteswapped "224-p1.p1") is set to <code>0xDB</code>, debugging features will be available.

===Program Menu===
[[Image:Twinsprites_debug1.png|Main debug menu, accessed by holding Player 2's A,B,C, and D buttons on boot]]

The main debug menu, "--- PROGRAM MENU ---", is accessed by holding down Player 2's A, B, C, and D buttons on boot.

===Select Button Menu===
[[Image:Twinsprites_debug2.png|Another debug menu, accessed by pressing Player 1 Select]]

Another debug menu is available by pressing Player 1 Select at any time.

==The Last Blade==
The Last Blade has a tool menu; more research is needed. (This was discovered on 2ch. Is this the same menu that you get with debug dip 2-4?)

In "234-p1.bin" (un-byteswapped?) make these changes:
* 0x5F5F4: 0xAA → 0x40
* 0x5F5F5: 0xF3 → 0xAF

==Viewpoint==
Viewpoint has a special test/debug type menu. This was discovered by Razoola on the CD system while working on the Universe Bios but also works on the MVS/AES versions of the game.

In "051-p1" make this change:
* 0x3FFFF: 0x7F → 0xFF

When game is running press START+SELECT at the same time, the game will pause and you will see the word 'PAUSE' in the top right corner. Pull the joystick DOWN and the new menu will appear.

==Todo==
* [http://sudden-desu.net/entry/disabled-debug-functions-in-neo-bomberman Neo Bomberman's debug menu and "DEBUGING(sic) MONITOR"]
* Other games are likely to have something lurking in them...

68k instructions timings

2016-07-31T20:27:36Z

Freem: /* Long */ text to table

TODO: CSS template for cputiming is ugly and broken.

Mirroring information from http://oldwww.nvg.ntnu.no/amiga/MC680x0_Sections/mc68000timing.HTML

The number of bus read and write cycles is shown in parenthesis as (r/w).

In the following tables the headings have the following meanings:
* An : Address register operand
* Dn : Data register operand
* ea : Operand specified by an effective address
* M : Memory effective address operand

To get the execution time, multiply the cycles count by 83.33ns ([[Clock|1/12MHz]]).

A [[68k interrupts|VBlank interrupt]] lasts exactly 40 lines * 384 pixels * 2 = 30720 cycles (2.56ms).

=Effective address operand calculation=

This table lists the number of clock periods required to compute an instruction's effective address. It includes fetching of any extension words, the address computation, and fetching of the memory operand.

Note: there are no write cycles involved in processing the effective address.

DIVS,DIVU - The divide algorithm used by the MC68000 provides less
than 10% difference between the best and the worst case
timings.
MULS,MULU - The multiply algorithm requires 38+2n clocks where
n is defined as:
MULU: n = the number of ones in the <ea>
MULS: n = concatanate the <ea> with a zero as the LSB;
n is the resultant number of 10 or 01 patterns
in the 17-bit source; i.e., worst case happens
when the source is $5555

68k instructions timings

2016-07-31T20:24:01Z

Freem: /* Byte and word */ text to table

TODO: CSS template for cputiming is ugly and broken.

Mirroring information from http://oldwww.nvg.ntnu.no/amiga/MC680x0_Sections/mc68000timing.HTML

The number of bus read and write cycles is shown in parenthesis as (r/w).

In the following tables the headings have the following meanings:
* An : Address register operand
* Dn : Data register operand
* ea : Operand specified by an effective address
* M : Memory effective address operand

To get the execution time, multiply the cycles count by 83.33ns ([[Clock|1/12MHz]]).

A [[68k interrupts|VBlank interrupt]] lasts exactly 40 lines * 384 pixels * 2 = 30720 cycles (2.56ms).

=Effective address operand calculation=

This table lists the number of clock periods required to compute an instruction's effective address. It includes fetching of any extension words, the address computation, and fetching of the memory operand.

Note: there are no write cycles involved in processing the effective address.

DIVS,DIVU - The divide algorithm used by the MC68000 provides less
than 10% difference between the best and the worst case
timings.
MULS,MULU - The multiply algorithm requires 38+2n clocks where
n is defined as:
MULU: n = the number of ones in the <ea>
MULS: n = concatanate the <ea> with a zero as the LSB;
n is the resultant number of 10 or 01 patterns

Freem: notes on the STSOUND driver from Leonard of Oxygene's 3d demo

The '''STSOUND''' engine is found in the NeoGeo 3D! demo by Leonard of Oxygene. It is notable in that it uses the SSG portion of the YM2610 to playback an Atari ST song.

==Description==
Leonard describes the engine as follows:
<blockquote>"68k only send a "tick" command at 50hz (ATARI music are 50hz). Then Z80 wake up at 50hz, and depack YM registers (all data is packed in Z80 ROM, the packed music is about 43KB). And then the magic trick is that NeoGeo has a YM2160 chip, far better than ATARI YM2149. BUT, the YM2160 has a SSG part (simple sound generator), which is hardware compatible with YM2149 :) So no software emulation, I simply put the registers into the SSG par[t] of the YM2160" [http://www.pouet.net/prod.php?post=607543 (quoted post)]</blockquote>

==RAM Usage==
* <code>$F800-$F81F</code> – command buffer (32 bytes)
* <code>$F820</code> – previous command (1 byte)
* <code>$F821</code> – current command (1 byte)
* <code>$F822</code> – music data pointer (2 bytes)

==Command Codes==
{|class="wikitable"

! Code || Description
|-
| 0x01 || Slot Switch

| 0x03 || Reset

==Code==
The bulk of the work is done in Command 0x10, which is sent from the 68K at 50Hz.

Freem: /* Homebrew */ small edits, also preparing for another sound driver info page

__NOTOC__
:''Mainspace pages of interest: [[Sound driver]], [[Sound drivers list]], [[YM2610]], [[YM2610 registers]], [[Z80/YM2610 interface]], [[68k/Z80 communication]]''

==Driver Overview==
The primary source of sound drivers was SNK. Most third parties stuck to using the MAKOTO series (and the Mr.NORIC driver on CD). ADK created their own in-house sound driver as well.

===SNK===
SNK had multiple sound drivers, starting with one labeled "Mr.Pac", and ending with "Sound Driver(ROM)Ver 1.9".

====Mr.Pac====

MAKOTO appears to be an evolution of the Mr.Pac driver, as its first appearance is marked "Ver 2.0a".

* '''"Ver 2.0a by MAKOTO.03/04/05 to SK"''' – Used in games from 1992 (starting with Mutation Nation) to 1995 (Goal! Goal! Goal!).
** Date: Heisei 3 (1991) April 5th
* '''"[[MAKOTO V3 driver|Ver 3.0 by MAKOTO.04/03/10 to SK]]"''' - Used in games from 1992 (starting with King of the Monsters 2) to 2001 (Jockey Grandprix, encrypted). Also found in the Neo-Geo CDZ BIOS.
** Date: Heisei 4 (1992) March 10th
* '''"Ver 3.2 by MAKOTO.97/06/01 to SK"''' – Found in the Samurai Spirits RPG Neo-Geo CD game.
* '''"Ver 8.3 by MAKOTO.98/05/07 to SK"''' – Found in later games, from 1998 (Neo Geo Cup '98) to 1999 (Prehistoric Isle 2).

====Mr.Noric====
:''More Information: [[User:Freem/Sound Drivers/Mr.Noric]]''
* '''"Ver 3.0 by Mr.Noric.1993/11/10 14:00"''' – Sound driver found in most CD games. Also found in the Neo-Geo CD (front and top loader) BIOS.

User:Freem/Sound Drivers/MVSTracker

2016-07-09T17:42:09Z

Freem: /* Modified (v0.2, 08Sep2006 by Kaneda) */ some information about the modified version

The [[MVSTracker]] driver exists in two versions:
# The original version by Ivan Mackintosh
# The modified version by Pascal and Kaneda

The latter version of the engine is able to target the Neo-Geo and Megadrive/Genesis. It splits out common routines and macros into separate files.

[http://www.culturaneogeo.com/entrevistajeffkurtzeng.htm According to Jeff Kurtz], this driver does not work on hardware. It seems that the required wait times for the address and data writes are not in place. (This is true for both the original and modified versions.)

=Original Version (v0.1)=
The original MVSTracker Z80 driver is contained in a file called <code>modplay.asm</code>.

* <code>UseChannel</code> (byte) — Current ADPCM-A channel to use

==Macros==

* <code>RAMARRAY</code> — define a series of bytes in RAM?
* <code>sendDEPortA</code> — push af, do rst 0x08 (write to ports 4/5), pop af
* <code>sendDEPortB</code> — push af, do rst 0x10 (write to ports 6/7), pop af
* <code>loadDEinstrX32</code> — do rst 0x18; "instrument# 0..31 multiply by 32; result in de"

==Code==
(todo; this is going to take a bit to clean up and format into wiki syntax)

=Modified (v0.2, 08Sep2006 by Kaneda)=
The modified version of the MVSTracker driver is split into multiple files:
* <code>common_func.inc</code> – Shared functions between Megadrive/Neo-Geo drivers.
* <code>common_macro.inc</code> – Shared macros between Megadrive/Neo-Geo drivers.
* <code>common_vars.inc</code> – Shared variables between Megadrive/Neo-Geo drivers.
* <code>modplay_md.asm</code> – Megadrive/Genesis Z80 sound driver code.
* <code>modplay_ng.asm</code> – Neo-Geo Z80 sound driver code.

This version of the code is meant to be assembled with [https://github.com/vhelin/wla-dx/ WLA-DX]. The Neo-Geo driver code has been reformatted and updated to work with the new common files, but is mostly unchanged from the original version.

The wiki

2016-04-18T08:14:49Z

Freem: lick joe licks the buttons

==Main rule==

Knowledge isn't an excuse for being a dick. Keep your ego at the door, please. By posting information here, you know that it's going in the wild. If you want credit, you can sign (important) information, but don't expect people to care about it.

==How to edit==

For those who are unfamiliar with wiki editing and don't want to go through lenghty tutorials, here's a short summary of the basics:

*Pages can be created, edited or deleted by any registered user. All operations are logged and can be reverted ("view history" tab).
*Each edit is signed by your username and timestamp.
*Links to existing pages are in blue or purple, links to needed pages are in red.
*When editing, clicking on the "Show preview" button won't log anything, "Save page" will.
*Marking an edit as "minor" allows to differenciate important changes in logs and correct typos without having the update appear on the front page.
*As stated in all edit pages: the content you submit will be placed under the [http://www.gnu.org/licenses/fdl-1.3.en.html GNU FDL]. This is not the best place to keep things secret.

Mediawiki uses a special markup language for formatting:
*Links to other pages look like this: <nowiki>[[Page name]]</nowiki>
*They can be renamed like this: <nowiki>[[Page name|Link text]]</nowiki>
*Links to categories look like this: <nowiki>[[:Category:Category name]]</nowiki> and can also be renamed with a |.
*Links to other sites look like this: <nowiki>[[http://www.com This is an external link]]</nowiki>
*Pictures can be inserted like this: <nowiki>[[File:image.jpg|thumb|This is a thumbnail and will be placed on the right]]</nowiki>
*Or simply like this, to display them in full size: <nowiki>[[File:image.jpg]]</nowiki>
*'''Bold''' looks like <nowiki>'''this'''</nowiki>, ''Italic'' looks like <nowiki>''this''</nowiki> (those are apostrophes)
*Headlines are made by using = characters: =Title= is the biggest, ====Title==== is the smallest
*Table of contents are automatically generated for pages containing multiple headlines
*Categorizing a page is done by adding tags like this: <nowiki>[[Category:Category_name]]</nowiki>, a page can belong in multiple categories.
*Tables are made using characters: {| starts a table, | starts a new cell, |- starts a new line, |} ends a table. Each of those characters need to be at the start of a new line.
*CSS and HTML markup can also be used most of the time.

*To create a page, just type its URL or make a link to it and click "create". There can't be 404 errors here, any link to pages or files which don't exist give a "create" page.
*Member pages can be created and edited only by the associated member. These can hold informations about yourself, your current projects...

==Editing guidelines==

*To avoid creating duplicate pages, page names shouldn't contain upper case letters, except for the first one and for acronyms. Intra-wiki links are case sensitive.
*Try to keep page names singular.
*To avoid broken links to pictures or screenshots, please make a local copy by uploading them here (be sure you have the right to).
*If a picture has to be updated with major corrections (like a chip pinout for example), try to delete the wrong version as to avoid search engines linking to wrong information.
*Don't hesitate to sign the informations you add if you think you discovered something or to specify the source if not.
*It's perfectly okay to make 2-characters edit to correct English mistakes for example, as long as those edits are marked as "minor".
*Links to other pages should ideally be made only once in a page (where it's the most visible or relevant if possible).
*Category tags should be placed at the bottom of the pages sources.
*Don't forget that the Neogeo is a console, and that a console is obviously made to earn money but also for '''fun''' !

==Templates==

===CSS===

Common.css can be found here: [https://wiki.neogeodev.org/index.php?title=MediaWiki:Common.css].

===Binary register definitions===

[[Template:16BitRegister]] and [[Template:8BitRegister]] can be used to display such tables:
{{16BitRegister|High byte|8|Lower byte|8}}

The code for this one is: <pre><nowiki>{{16BitRegister|High byte|8|Lower byte|8}}</nowiki></pre>

Arguments go by pairs: starting from 0, even ones are the text definition, odd ones are the size of it (in bits). The total size must be equal to the register's length or else the table will be broken and browsers might be unhappy.

===Registers, RAM locations and signal names===

The [[Template:Reg]] and [[Template:BR]] are used to refer to named registers and RAM locations. Their address is automatically added in parenthesis. For example:

<pre><nowiki>{{BR|BIOS_UPSIZE}}</nowiki></pre>

Gives: {{BR|BIOS_UPSIZE}}

[[Template:Sig]] is used to refer to electrical signals and provide a link to the [[signal names]] page for details.

===Chip pinout templates===

ODG (OpenOffice Draw) files:
* QFP80 package: http://furrtek.free.fr/noclass/neogeo/neo-zmc2.odg
* QFP64 package: http://furrtek.free.fr/noclass/neogeo/neo-257.odg

Grid is at 0.05", font is Courier New size 6.

Color proposals for buses and pin types (feel free to discuss):
*Green: cartridge slot connections
*Yellow: CPU address buses
*Blue: data buses
*Grey: ground
*Red: power
*Purple: control lines
*Magenta: clocks

:''Mainspace pages of interest: [[Sound driver]], [[Sound drivers list]], [[YM2610]], [[YM2610 registers]], [[Z80/YM2610 interface]], [[68k/Z80 communication]]''

==Driver Overview==
The primary source of sound drivers was SNK. Most third parties stuck to using the MAKOTO series (and the Mr.NORIC driver on CD). ADK created their own in-house sound driver as well.

===SNK===
SNK had multiple sound drivers, starting with one labeled "Mr.Pac", and ending with "Sound Driver(ROM)Ver 1.9".

====Mr.Pac====
:''More Information: [[User:Freem/Sound Drivers/Mr.Pac]]''
The original sound driver.

* '''"Ver 1.5b by Mr.Pac h Ber.02/01/08"''' – Used in the BIOS M1 driver, as well as the first four released games (NAM-1975, Baseball Stars Professional, Top Player's Golf, and Mahjong Kyoretsuden).
** Date: Heisei 2 (1990) January 8th
* '''"Ver 2.0 by Mr.Pac h Ber.02/02/14"''' – Used in games from 1990 (starting with Riding Hero) to 1998 (Blazing Star).
** Date: Heisei 2 (1990) February 14th

====MAKOTO====
:''More Information: [[User:Freem/Sound Drivers/MAKOTO]]''
MAKOTO appears to be an evolution of the Mr.Pac driver, as its first appearance is marked "Ver 2.0a".

* '''"Ver 2.0a by MAKOTO.03/04/05 to SK"''' – Used in games from 1992 (starting with Mutation Nation) to 1995 (Goal! Goal! Goal!).
** Date: Heisei 3 (1991) April 5th
* '''"[[MAKOTO V3 driver|Ver 3.0 by MAKOTO.04/03/10 to SK]]"''' - Used in games from 1992 (starting with King of the Monsters 2) to 2001 (Jockey Grandprix, encrypted). Also found in the Neo-Geo CDZ BIOS.
** Date: Heisei 4 (1992) March 10th
* '''"Ver 3.2 by MAKOTO.97/06/01 to SK"''' – Found in the Samurai Spirits RPG Neo-Geo CD game.
* '''"Ver 8.3 by MAKOTO.98/05/07 to SK"''' – Found in later games, from 1998 (Neo Geo Cup '98) to 1999 (Prehistoric Isle 2).

====Mr.Noric====
:''More Information: [[User:Freem/Sound Drivers/Mr.Noric]]''
* '''"Ver 3.0 by Mr.Noric.1993/11/10 14:00"''' – Sound driver found in most CD games. Also found in the Neo-Geo CD (front and top loader) BIOS.

====Sound Driver (1995-2000)====
:''More Information: [[User:Freem/Sound Drivers/To SNK]]''

===ADK===
:''More Information: [[User:Freem/Sound Drivers/ADK]]''
ADK's sound driver was the work of M.Chiba (credited as "M.C" in later versions) between 1990 and 1996. There are a number of drivers missing from this list, especially CD games.

==Driver Overview==
The primary source of sound drivers was SNK. Most third parties stuck to using the MAKOTO series (and the Mr.NORIC driver on CD). ADK created their own in-house sound driver as well.

===SNK===
SNK had multiple sound drivers, starting with one labeled "Mr.Pac", and ending with "Sound Driver(ROM)Ver 1.9".

User:Freem/Sound Drivers/Mr.Pac

2016-04-15T20:50:05Z

Freem: add dates and update a few small things

The '''Mr.Pac''' Sound Driver exists in two versions:
* <code>Ver 1.5b by Mr.Pac h Ber.02/01/08</code> (January 8th, 1990)
* <code>Ver 2.0 by Mr.Pac h Ber.02/02/14</code> (February 14th, 1990)

The information on this page primarily deals with the [[SM1|first version of the driver as it appears on the SM1 chip]].

==Origin==
It is likely that this sound driver is based off of the one found in Beast Busters, which contains this signature:
<pre>SOUND CONDUCTER Ver 1.0a for YM2610(OPNB) by Mr.Pac hector Ber.1989/06/17</pre>

User:Freem/Sound Drivers/Mr.Pac

2016-04-12T02:44:05Z

Freem: add "SOUND CONDUCTER Ver 1.0a for YM2610(OPNB) by Mr.Pac" reference from Beast Busters; seems to be the first version of the sound driver (later changed for Neo-Geo)

The '''Mr.Pac''' Sound Driver exists in two versions:
* Ver 1.5b by Mr.Pac h Ber.02/01/08
* Ver 2.0 by Mr.Pac h Ber.02/02/14

The information on this page primarily deals with the [[SM1|first version of the driver as it appears on the SM1 chip]].

==Origin==
It is likely that this sound driver is based off of the one found in Beast Busters, which contains this signature:
<pre>SOUND CONDUCTER Ver 1.0a for YM2610(OPNB) by Mr.Pac hector Ber.1989/06/17</pre>

* Timer A seems to be used for sound effect playback. (The Timer A value is also stored in 0xFAD3 (lower 2 bits) and 0xFAD4 (upper 8 bits) in the SM1/BIOS driver)
* Timer B is used as the tempo for music playback. (The Timer B value is also stored in 0xFAD4 in the SM1/BIOS driver)

Freem: make note of ASO2 using METRIC_DATA

__NOTOC__
'''freem'''! Also known as AJ 187 in some circles; <code>freem</code> or <code>freem_inc</code> on #neogeodev IRC. Responsible for the NeoFixFormat plugin for [[YY-CHR|YY-CHR.NET]] and some other tools.

==Sub-Pages==
{{Special:PrefixIndex/{{FULLPAGENAME}}/}}

==Various todo==
===Wiki===
* More screenshots of [[Homebrew software]]
* Make pages for said homebrew software
* Edit various pages
** Stop being lazy and correct the [[Fix graphics format]] page
** Work on the [[NeoGeo programming cheatsheet]]
** Create a new [[Hello world tutorial]] (somewhat in progress, though [http://ajworld.net/neogeodev/beginner/ externally] for now)
* Make new pages as needed ([[Special:WantedPages]])

===Hardware===
* Get money so I can buy some dang real hardware
** AES (with US BIOS so I can dump it, because it appears nobody has done that?)
** Neo-Geo Pocket Color (eventually two for testing system link capabilities and such)
** JEIDA v3 compatible Memory Card (maybe multiples for dealing with self-made software/utils that uses non-standard Neo-Geo formats)
** NGP Link Cable (at least 2; one for keeping in pristine condition and the other for a silly idea I have regarding NGPC <-> Neo-Geo/CD consoles)
** NGP Wireless Communication Unit (for another silly idea regarding the realization of [[SNK Patents|patent]] EP 0997172 A1)

* Build some things
** PC-2-Neo cable (parallel)
** MIDI ↔ Neo-Geo controller port cable, if possible
** Neo-Geo Pocket Link port ↔ Neo-Geo controller port cable (see above)

* Learn how to not suck at electrical engineering in order to do the following:
** Make a simple dev cart.
** Experiment with RAM in places it normally shouldn't be (C ROMs, S ROM, V ROMs)...
*** Determine if having it in P and M ROMs are worth the effort.
** However many years down the line, once I've figured out how to not suck, and if nobody else has done it by then, see about replicating certain features of later SNK chips (e.g. NEO-PCM(!!), NEO-CMC, NEO-SMA).

===Software===
* Continue overall work on freemlib
** Make sure ISC License is the best choice??
** Create/Add more library code
** Finish up existing examples in pipeline
** Add <code>TITLE_x.SYS</code> files for other examples
** Create more examples
** Work on Sound driver
* Finish up C# palette generator program
* Create various other tools:
** [http://www.mapeditor.org/ Tiled] map to data converter
** A tool for creating Fix layer "nametables"
** Some sort of ADPCM conversion toolbox (combine ADPCM-A encoder, ADPCM-B encoder, and V ROM/.PCM builder)
** Others not listed here
* Oh, and make some games, of course ;)

===Reverse Engineering===
* System ROM fun
** AES Development BIOS
** Whichever other MVS and AES system ROMs I was working on
** CDZ system ROM
** Front loader CD system ROM
* Sound Drivers
** SNK Sound Drivers
** Homebrew Sound Drivers
* Games
** Alpha Mission 2/ASO2 uses METRIC_DATA... wtf is METRIC_DATA for anyways??

Freem: add link to technique description thread

[[Image:Screencap_diff.png|thumb|Screenshot]]
[[Diff]] is a Neo-Geo CD demo by citavia, released at Revision 2016.

It cleverly uses 2 groups of 40 sprites spaced 8 pixels apart as a double-buffered canvas, where each tile is assigned to a different palette. Drawing to the canvas is done at 30 FPS only by updating the [[palette RAM]].
