[[File:harddips.png|right|thumb|DIP switches state '''viewer''' in the [[system ROM]].]]

Physical DIP switches on MVS boards used to configure various options like the number of coin chutes and the multiplayer link. The switches states are read through register {{Reg|REG_DIPSW}} as a byte (0 is on).

* Switch 8: Freeze - pauses the game (done by software in a [[system ROM]] call)
* Switch 7: Enable freeplay (player start doesn't require credits)
* Switch 6: Enable communication
* Switches 4~5: [[Multiplayer]] link cab number (in binary: 1, 2, 3, 4)
* Switch 3: Enable [[mahjong controller]]
* Switch 2: Number of [[coin switch|coin chutes]] (1 or 2 Euro & Japan, 2 or 4 on USA)
* Switch 1: Bring up the system ROM menu at boot

There are no such switches on home and CD systems.

The {{PCB|MV4}} has an unused footprint for a second set of DIP switches "DSW2" which could have been read through register {{Reg|REG_SYSTYPE}}.

PAT file

2018-11-06T16:27:13Z

Razoola: Updated incorrect information.

PAT files contain structured data to patch already loaded [[Z80]] code. They're used to replace [[YM2610#ADPCM|sound samples]] address tables originally loaded from [[Z80 file]]s when different [[PCM file]]s are loaded.

* Maximum file size: 2048 bytes ?
* Type code: 5
* Loaded into: Z80 code RAM

=Format=

Blocks of 5 word (16 bit) values:

* Patch address in bytes. $0000 means end of file. All the $0001~$FFFF range seems to work.

* First data word is (/2), byteswapped and written to address
* Second data word is (/2)-1, byteswapped written to address + 2
* Third (optional) data word is (/2), byteswapped and written to address + 5
* Fourth (optional) data word is (/2)-1, byteswapped written to address + 7

If the third data word is $0000, both the third and fourth patches are skipped.

=Offset=

When loading a PAT file (see [[loading files]]) the bank number and destination address parameters can be used to add an offset to all the patched values. This allows PCM data associated with a PAT file to be loaded into different regions of PCM DRAM without the need of multiple PAT files.

Code snippet from the TOP-SP1 [[system ROM]] which handles this:

<syntaxhighlight>
C0BFAE MOVEQ #0x0,D0 Clear D0 00000000
C0BFB0 MOVE.B (0x7EDB,A5),D0 Bank number byte to D0 000000bb
C0BFB4 SWAP D0 00bb0000
C0BFB6 LSL.L #4,D0 0bb00000
C0BFB8 OR.L (0x7EF4,A5),D0 Insert destination addr. 0bbddddd
C0BFBC LSR.L #8,D0 000bbddd
C0BFBE MOVE.W D0,(0x7736,A5) Offset will be: bddd

161-in-1 Series 1

2018-07-15T17:25:03Z

Razoola: /* Version 2 design flaw & stability fix */

Relatively recent [[multicarts|multicart]] with a software menu.
At least 2 versions of this cart exists.

=Version 1=
===Boards===

[[File:55lv100s.png|thumb|55LV100S draft pinout]]

Uses a bunch of uncommon Fujitsu SSOP70 55LV100S 128MB flash chips, which some say were salvaged from other arcade machines.

* 3 for P (384MB)
* 5 for V (640MB)
* 16 for C (2GB)
* 1 for S
* 1 for M

===PROG board===

*UP1: EPM3256 CPLD for [[P ROM]] and mcu control. Full 68k address and data bus connected. Address bus for the P ROMs comes only from the CPLD. Connected to RESET, PORTWE, PORTOE, ROMOE, AS, RW. JTAG port is JP1.

*UV1: EPM3256 CPLD for [[V ROM]] bankswitching and {{Chipname|PCM}} replacement. JTAG port is JV1.

*U3: Microcontroller (sanded-off PIC ?). 5V-powered, 8bit input bus (3.3V pullups in SIL array) and 8bit output bus to UP1. Not present on earlier multicarts of the same origin with less games. Programming port is J8.

===CHA board===

Another EPM3256 CPLD for the [[C ROM|C]], [[S ROM|S]] and [[M1 ROM|M]] ROMs. A smaller CPLD is used to replace {{Chipname|NEO-ZMC}}.

Uses a daughterboard with 14 flash chips. Lots of unused footprints for additional chips.

=Version 2=
This version still uses salvaged memory chips from Excite pachislots, with strange adapter legs.

===Version 2 design flaw / stability fix===
Version 2 has a design flaw compared to version 1 which causes instability espicially on the MV-4F where it will not really work at all. Comparing version 1 to version 2 PCB's it was noticed version 1 PROG boards (solder side) has pins PDWAIT1 and PDTACK bridged, this bridge is missing on version 2 PCBs.

Adding the bridge between these pins allows version 2 to work correctly on the MV-4F and probably makes it more stable on other MVS hardware also. See pictures below.

=Programming (Version 1 / Version 2)=

Infos by [[User:Razoola|Razoola]].

Games have their [[68k interrupts|v-blank]] interrupt code patched to allow going back to the game list menu by holding 1UP start down for 5 seconds. This button check however is quite flawed given it tests the entire byte of REG_STATUS_B and not bit 0 only. The result of this oversight by the coders means the game list menu will not reappear if running on AES hardware (via converter), if a memory card is present, or either 1UP select, 2UP start or 2UP select is also pressed.

Address [[68k memory map|0x2FFFE0]] (word) is used to communicate with the mcu for storage and retrieval of the game's [[software DIPs]] settings and the menu's current position.

Game selection is done through a set of 5 registers; 0x2FFFF0, 0x2FFFF2, 0x2FFFF4, 0x2FFFF6 and 0x2FFF00 (in that order). Each game is identified by a single word value (hex format) which is its position in the game list, KOF99 is 0x0015 for example. What is currently known about these registers is as follows;

[[68k memory map|0x2FFFF0]]
*0x0F0F is always written by the UI but testing seems to show any value will have the same effect.
*Prep MCU to receive game change info (must be written first).

[[68k memory map|0x2FFFF2]]
*Number of game to be selected always written by the UI.
*purpose unknown

[[68k memory map|0x2FFFF4]]
*Number of game to be selected always written by the UI.
*purpose unknown

[[68k memory map|0x2FFFF6]]
*Number of game to be selected always written by the UI.
*Purpose unknown but a value must be written!

[[68k memory map|0x2FFF00]]
*Number of game to be selected always written by the UI.
*Swaps ROM regions to new game (must be written).

Some notes about game swapping.

*To get back into the 161-in-1 game list the game number is set to 0x0000.
*Looking at Art of Fighting 2, register 0x2FFFF4 is not used when jumping back to the game list (unsure if this is true for all games).
*ROM regions (P,S,F,M and V) switch to the game based on the value written to 0x2FFF00 regardless of the values written to either 0x2FFFF2, 0x2FFFF4 or 0x2FFFF6.
*A game can be chosen by writing to registers 0x2FFFF0, 0x2FFFF6 and 0x2FFF00 only. Unknown if all games would function correctly however (lots of play testing required).
*No way is currently known to instruct the cart to configure a single ROM region to a different game than whats held in the other regions. Based on what is known already this is probably not possible unless there are registers unused by the UI coding that can be used to instruct the MCU to do it.

=Known Game Issues (Version 1 / Version 2)=

*Aero Fighters 2 - Will not play correctly unless in Japanese region (button check code inserted into ROM over game data).
*Magical Drop II - Hiscore table is broken when drawn to screen (the start button trigger timer var stored at 0x10FF20, a region used by the game and MESS_OUT). This issue may affect other games also.
*Magical Drop III - Hiscore table is broken when drawn to screen (the start button trigger timer var stored at 0x10FF20, a region used by the game and MESS_OUT). This issue may affect other games also.
*Blue's Journey - Game will not have sound until system soft reset (probably due to corrupted Z80 ROM image).
*Puzzle Bobble 2 - Can causes crash when selected from the game list. Looks dependant on MVS type (happens on my MV-1FS but not MV-1FT). The game works correctly once a soft reset is done after the crash.
*Alpha Mission II - Game name displayed in the testmode softdip settings screen is byte flipped (stored incorrectly in the carts game name tables).
*Metal Slug 3 - Has NGH of 0x299 (mslug6 hack). When in USA region the 'parental advisory warning' screen is corrupted. When set to Japanese language (softDIP) the Japanese how to play font is corrupted.
*Garou MOTW - Will crash when preforming Kim's B+C top attack, this due to 161-in-1 using the prototype version of the game.

There are probably other game issues also.

[[68k memory map|0x2FFFF0]]
*0x0F0F is always written by the UI but testing seems to show any value will have the same effect.
*Prep MCU to receive game change info (must be written first).

[[68k memory map|0x2FFFF2]]
*Number of game to be selected always written by the UI.
*purpose unknown

[[68k memory map|0x2FFFF4]]
*Number of game to be selected always written by the UI.
*purpose unknown

[[68k memory map|0x2FFFF6]]
*Number of game to be selected always written by the UI.
*Purpose unknown but a value must be written!

[[68k memory map|0x2FFF00]]
*Number of game to be selected always written by the UI.
*Swaps ROM regions to new game (must be written).

Some notes about game swapping.

*To get back into the 161-in-1 game list the game number is set to 0x0000.
*Looking at Art of Fighting 2, register 0x2FFFF4 is not used when jumping back to the game list (unsure if this is true for all games).
*ROM regions (P,S,F,M and V) switch to the game based on the value written to 0x2FFF00 regardless of the values written to either 0x2FFFF2, 0x2FFFF4 or 0x2FFFF6.
*A game can be chosen by writing to registers 0x2FFFF0, 0x2FFFF6 and 0x2FFF00 only. Unknown if all games would function correctly however (lots of play testing required).
*No way is currently known to instruct the cart to configure a single ROM region to a different game than whats held in the other regions. Based on what is known already this is probably not possible unless there are registers unused by the UI coding that can be used to instruct the MCU to do it.

=Known Game Issues (Version 1 / Version 2)=

*Aero Fighters 2 - Will not play correctly unless in Japanese region (button check code inserted into ROM over game data).
*Magical Drop II - Hiscore table is broken when drawn to screen (the start button trigger timer var stored at 0x10FF20, a region used by the game and MESS_OUT). This issue may affect other games also.
*Magical Drop III - Hiscore table is broken when drawn to screen (the start button trigger timer var stored at 0x10FF20, a region used by the game and MESS_OUT). This issue may affect other games also.
*Blue's Journey - Game will not have sound until system soft reset (probably due to corrupted Z80 ROM image).
*Puzzle Bobble 2 - Can causes crash when selected from the game list. Looks dependant on MVS type (happens on my MV-1FS but not MV-1FT). The game works correctly once a soft reset is done after the crash.
*Alpha Mission II - Game name displayed in the testmode softdip settings screen is byte flipped (stored incorrectly in the carts game name tables).
*Metal Slug 3 - Has NGH of 0x299 (mslug6 hack). When in USA region the 'parental advisory warning' screen is corrupted. When set to Japanese language (softDIP) the Japanese how to play font is corrupted.
*Garou MOTW - Will crash when preforming Kim's B+C top attack, this due to 161-in-1 using the prototype version of the game.

There are probably other game issues also.

Razoola: /* Command 3 */

The USER subroutine (not called, always jumped to by the BIOS) is required [[68k]] code which needs to perform actions according to the command value set in {{BR|BIOS_USER_REQUEST}}.

At the end of the routine, a jump to [[SYSTEM_RETURN|BIOSF_SYSTEM_RETURN]] is needed to give back control to the BIOS.

=Handling code=

<syntaxhighlight>
JT_User:
dc.l StartupInit
dc.l EyeCatcher
dc.l Game
dc.l Title

User:
move.b d0,REG_DIPSW
clr.l d0
move.b BIOS_USER_REQUEST,d0
lsl.b #2,d0
lea JT_User,a0
movea.l (a0,d0),a0
jsr (a0)
jmp BIOSF_SYSTEM_RETURN
</syntaxhighlight>

=USER_REQUEST values=

==Command 0==
Initilization of the soft/debug [[DIPs]] in the [[68k user RAM]]. Used only once, when the game is started for the first time on a MVS system (probably when the BIOS doesn't find the game's NGH number in the [[backup RAM]]).

Set {{BR|BIOS_USER_MODE}} to 0 during operations, and don't forget to kick the watchdog as interrupts are disabled.

Initilization of the rest of the user RAM, the display, and I/O.

[[Viewpoint]], which has its backup RAM save pointer set to $100000 (header $10E) and game save size set to $0200 (header $112) does this:
<syntaxhighlight>
move.b #$00,BIOS_USER_MODE
lea $100000,a0 ;Start of game save block
move #$001F,d1 ;32*4 longword writes = 512 bytes
moveq #0,d0
.cl:
move.l d0,(a0)+
move.l d0,(a0)+
move.l d0,(a0)+
move.l d0,(a0)+
dbf d1,.cl
move.b d0,REG_WATCHDOG
...
jmp BIOSF_SYSTEM_RETURN
</syntaxhighlight>

Typical use is load default data (default rankings, etc) into work-backup area, then jump to SYSTEM_RETURN.

==Command 1==
Show the game's own boot logo animation (when [[68k program header|$114]] = 1).

This command by default is only called on an AES and not MVS. It is called once only at system start (before attract mode) and not again.

Later games by SNK trick the MVS bios into calling this subroutine. They do this by first moving and then executing code from RAM during their command 2 routine. This code determines the games SLOT location and then stores this location to address 0xD00058 (See routine from 0xA910E in KOF99).

It is this manipulation of used bios RAM that can cause games to boot out of sequence on multi slot hardware. Another side affect is the new eye catcher does not display right away, at least one attract mode sequence must be completed first. SNK appear to have done this with the aim of updating the original spinning logo with their new version and thus this method is not advised if you want an eye catcher to show on MVS hardware. Instead it is advised to call your own the eye catcher routine from within command 2 (attract mode) only. See Aero Fighters 2 as an example, it has both the Neo Geo eye catcher and a VideoSystem eye catcher.

==Command 2==
Show the game's demo, this means anything related to attract mode. (the recommended duration is ?).

==Command 3==
Show the game's title screen. This is called when a coin is inserted on [[MVS systems]] only and is never called on [[MVS systems]]. {{BR|BIOS_COMPULSION_TIMER}} is used as a count-down timer for auto-start.

Some games write 0x01 to 0x10FEC5 in this routine. It stops the bios calling command 3 twice after game over if credits are already in the system (attract mode skipped). When 0x00 the bios will initiate another command 3 a few frames after the first. This causes the title page to draw twice. This could be a bios bug which SNK fixed by adding this variable in a later bios revision (needs confirming).

To see an example compare Art or Fighting to Art of Fighting 2 after game over.
