BIOSF_LOADFILE ($C00552): Load file from CD (with animation)
A0 points to a file list, with entries having the following format:
- The file name, ends with 0 (in 8.3 format)
- The destination bank (byte)
- Eventual padding byte to align the destination to an even address
- Destination (longword)
The list must not exceed 32 files, and must end with a 0 byte.
Example:
"STAGE_2.SPR" 0x02 0x00 0x00001600
Loads STAGE_2.SPR at $201600 in the sprite DRAM.
For FIX, Z80 (, PAT ?) and PCM files, the destination address is multiplied by 2 (8bit busses).
The destination memory is automatically chosen according to the file's extension.
