| == BIOSF_UPLOAD ($C00546): Upload data to [[DRAM]] ==
| | The BIOSF_UPLOAD ($C00546) call copies data to the NeoGeo CD [[DRAM]]. |
|
| |
|
| <pre>
| | The parameters are: |
| BIOS_UPSRC (32bit): Source (Long)
| |
| BIOS_UPDEST (32bit): Destination (Long)
| |
| BIOS_UPSIZE (32bit): Size (Long)
| |
| BIOS_UPZONE $10FEDA (8bit): Zone (Byte, 0=PRG, 1=FIX, 2=SPR, 3=Z80, 4=PCM, 5=PAT)
| |
| BIOS_UPBANK (8bit): Bank (Byte)
| |
| </pre>
| |
|
| |
|
| For FIX, Z80 (, PAT ?) and PCM upload, the destination has to be multiplied by 2 (8bit busses).
| | *{{BR|BIOS_UPSRC}} (longword): Data source address |
| The SPR bank size is 1MiB (4 banks), PCM bank size is 512KiB (4 banks). The other zones aren't banked.
| | *{{BR|BIOS_UPDEST}} (longword): Data destination address |
| | *{{BR|BIOS_UPSIZE}} (longword): Data size |
| | *{{BR|BIOS_UPZONE}} (byte): Zone/method, see below |
| | *{{BR|BIOS_UPBANK}} (byte): DRAM bank |
|
| |
|
| BIOS_UPDEST (and BIOS_UPSRC ?) is incremented by the size upon completion, which allows to do multiple consecutive uploads. | | When the call returns, BIOS_UPDEST points to the end of the copied data, allowing multiple consecutive uploads without setting the destination address again. |

| | ==$06: Copy palette words (DMA)== |
| *$FF016F.b=0 enable interrupts ?
| | Loads word copy DMA microcode. |
| | |
| | ==$07: Copy compressed sprite graphics (CPU)== |
| | The first longword's value indicates the size of the '''compressed''' data, BIOS_UPSIZE isn't used. |
| | When a longword zero is copied, the following longword indicates how many zero longwords to insert. |
| | |
| | This method allows compression of large transparent zones. Is it ever used by games ? |
| | |
| | ==$08: Copy PRG words (DMA)== |
| | Same as method $00. |
| | |
| | ==$10: Copy PRG longwords (CPU)== |
| | Size must be a multiple of 4. |
| | |
| | ==$11: Copy Fix graphics words (CPU)== |
| | The destination address must be multiplied by 2 (8bit bus). Size doesn't have to be multiplied, but has to be an even number. |
| | |
| | ==$12: Copy Sprite graphics longwords (CPU)== |
| | Size must be a multiple of 4. |
| | |
| | ==$13: Copy Z80 program bytes (CPU)== |
| | The destination address must be multiplied by 2 (8bit bus). Size doesn't have to be multiplied, but has to be an even number. |
| | |
| | ==$14: Copy PCM bytes (CPU)== |
| | The destination address must be multiplied by 2 (8bit bus). Size doesn't have to be multiplied, but has to be an even number. Copies over 1MiB are possible, the bank is incremented automatically. |
| | |
| | Difference with $04 ? |
| | |
| | ==$15: Install PAT file== |
| | Same as method $05. |
| | |
| | ==$16: Copy palette longwords (CPU)== |
| | Size must be a multiple of 4. |
| | |
| | ==$17: Copy compressed sprite graphics (CPU)== |
| | Same as method $07. |
| | |
| | ==$18: Copy PRG longwords (CPU)== |
| | Same as method $10. |
