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.
