Amiga verification export format

"ROM" export format exclusively for verifying whether the Amiga emulation in Furnace is correct.

do not assume this is the actual ROM export! it is nothing more than a register dump kind of thing...

process

enable the setting in Furnace to unlock the export option by adding this to furnace.cfg:

iCannotWait=1

go to file > export Amiga validation data...

put sample.bin, sbook.bin, seq.bin, wave.bin and wbook.bin in this directory.

type make. you need vasm (68000 with Mot syntax) in order for it to work. alternatively, type:

vasmm68k_mot -Fhunkexe -kick1hunks -nosym -o player player.s

run player on Amiga. it should play the exported song.

notes

may not work correctly if you have slow/fast memory! sequence and wave data should reside in fast memory but I haven't figured out how to...
