I’m normally into the homebrew NES articles but this has no details and no links to details I can find so I’m inclined to vote blogspam. Is there a ROM, a write up, anything? Nevertheless it’s impressive to ship for NES / FAMICOM and the GameBoy. Was the source all the same? I’d love to read more from OP.
