MEG-4 MOD Player

This is a little test tool I wrote to check if Amiga MOD playback / export works as expected.

Usage

./modplayer <in.mod> [out.mod]

IMPORTANT: it does not play the .mod file as-is. Instead it imports the file into MEG-4's internal format, and then it uses the MEG-4 DSP chip to play the converted data. If everything went well, you should hear something VERY close to the original file, but not identical (for example .mod stores stereo wave samples up to 64k, but MEG-4 DSP only supports mono samples no bigger than 16k each; stereo balance (0x8 and 0xE8), pattern command effects (0xE6, 0xEE, 0xEF) simply skipped, and position jump (0xB) interpreted as jump to the x*64th row (which could be off if pattern break 0xD also used), etc. etc. etc.)
