(Since my developing skills are near zero, so eh…)
Basically, a music player that converts (any sort of tune) into a chiptune (in real-time?) and plays it. Various sound sets can be chosen – from 8 bit ones, to 16 bit… super mario (snes) sound set, etc. Bonus points if its CLI, made using c++ code.
Now. That said, if you just want to map input MIDI’s or some other raw format describing the actual tones (not just an audio waveform)- that would be doable with a little table lookups.
Honestly… what I had in mind was a modern song (with vocals, etc) being converted in real-time through a “winamp-esque” music player (think: “Open file”, then after the song is chosen, “Converting to chiptune, please wait…” then the song is played.). But since this is a stupidly difficult task… then sure, I’m okay with a “standard” midi-to-chiptune converter.
