Game Boy to MIDI (and tracker) converters

Post by birdmanager6 »

I know I haven't been on this website for years, but since then, I have learned a lot and I wanted to showcase some projects I have worked on, MC2MID, TT2MID, and GHXM.

These are the first three in a series of programs that convert music from Game Boy and Game Boy Color music to MIDI format, or in GHXM's case, XM (FastTracker II).

They can be found here, complete with source code:

MC2MID (Mark Cooksey (GB/GBC) to MIDI)
https://github.com/turboboy215/MC2MID

TT2MID (Tiertex (GB/GBC) to MIDI)
https://github.com/turboboy215/TT2MID

GHXM (GHX (Shin'en GBC) to XM)
https://github.com/turboboy215/GHXM

All three of these programs are command-line and work with ROMs by specifying the sound data's bank number in hexadecimal. (GBS files currently aren't supported, but might be in the future.)
For lists of games each program supports, check the "README.md" file for the programs. A list of the bank values for each known game can be found here: https://drive.google.com/file/d/13ROJE_ ... sp=sharing

What I plan on working on next is a MIDI converter for the AudioArts GBC driver and a MOD converter for Climax's "IMEDGBoy" format (I have already reverse-engineered these two formats).

If you have any requests for specific GB/GBC sound engines or games you would like to see a MIDI/tracker converter for, please let me know and I will look into it. (In the future, I will also figure out the architecture of other systems so I can work on converters for those as well.)

That's really cool stuff!

I once thought about writing a "gb2mid" converter for Mark Cooksey's driver, but I never researched the sequence format.

Update: Added AudioArts to MIDI converter:

In my opinion, the AudioArts sound engine is one of the best-sounding, if not the best-sounding GBC sound engine.

This is interesting! Can it be used on games made by Japanese developers?

Finally completed my Climax to MOD converter!

It also works with the Game Gear format, since it's almost the same. Note that unlike other converters, this actually requires the individual "modules" to be extracted from the ROMs, and some games actually store all or most of them compressed using RNC/ProPack, so those need to be decompressed first (the compressor/decompressor can be found in the Devr's GB section, and needs to be run using DOSBox).

Yes, I do plan to add support for Japanese sound engines as well! After I complete my next converter, which is for Martin Walker's driver (most notably used in the first Earthworm Jim), I plan to start with one of the various drivers used in the Mega Man series, either Dr. Wily's Revenge or the Xtreme games.

Fun fact: the Game Gear version of Martin Walker's driver is used in Mega Man for Game Gear!

Nice! Hopefully someone can make some MIDIs of Rolan's Curse and Rolan's Curse 2 in the future! :D
