I use a supercard SD and it is not working... :(
Nice tunage btw :)
A merchant approaches you! o__O
"Yaargh, wish I had wares to sell ya!"
My first ever gameboy tune.
I used lsdj1 3.5b demo for it, running in goomba(a gb classic emulator for gba), which itself runs in gba mode on a nintendo ds.
I recorded directly from that setup.
If someone is interested and has a EZ-FlashIV i can post the savestate file somewhere.
