BIOSF LOADFILE

BIOSF_LOADFILE ($C00552): Load file from CD (with animation)
A0 points to a file information block made of:
 * The file name, ends with 0 (16 byte max)
 * The destination bank (8bit)
 * Eventual padding byte to align the destination
 * Destination (32bit)

Example (?): "STAGE_2.SPR",0x02,0x00,0x1600 loads STAGE_2.SPR at $201600 in the sprite DRAM.

For FIX, Z80 (, PAT ?) and PCM files, the destination is multiplied by 2 (8bit busses).

The destination memory is automatically chosen according to the file's extension.
