I came across this a while ago, but I was counting on an actual ROM release. It didn't happen [yet], but it still might be interesting to some.
MtChocolate wrote this little demo / music disk thing for the eight edition of Bakuon Kai, which is a chiptune party held in Tokyo.
Here's a video of it in an early stage, showing only the main screen. Apparently, it's been released on a cartridge as well. Keep an eye out. Maybe it will eventually appear on her webpage.
