Hey guys, guess what? I have music!

Unfortunately it doesn’t work very well. It uses patterns from the .it format, which is easier to load than I thought (yay for the BIT opcode \o/) but quite a pain to play. To be quite honest, I’d probably fare better just using LZSS-compressed VGM streams.

Enjoy the slightly glitchy music. Also, when you die or win, the game resets!

No source code, sorry – and here’s why:

…yep, all those files (using a tool I made, of course). Anyways:

But I might just sacrifice compactness for simplicity in the compo.

Are any of the module formats easy to play? To my understanding, it’s notoriously hard to get timing and effects right. .xm looks like one of the most logical to process but they all have specific, exacting playback rules.

Seems you’re using linux. Which distro are you using?

Hello,

If your target is Sega 8-bit your best bet is to look the .psdmod format exported by MOD2PSG2 (which as its name NOT imply is a full featured tracker for the SN chip in SMS/GG). Mod2Psg2 also allows importing VGM and MID to some extent, although your output .psgmod file won’t be as optimized as something made under proper constraints. There is a runtime playback library with Mod2Psg2 and its trivial to use.
