Small utility forwarding MIDI input messages to mGBA's native link "interface"

MidiToMGBA - MIDI input -> mGBA link

License: MIT

---

MidiToMGBA acts as a simple MIDI message forwarder, listening to a MIDI input device and passing on all MIDI messages to mGBA's internal link interface.

This previously was MidiToBGB, but BGB's TCP link is suboptimal for this task. Development thus moved on to a mGBA-centric solution.

Setup:

• If you want to use MidiToBGB with your DAW: Download and install a MIDI "loopback" driver, f.e. loopmidi by Tobias Erichsen
• Download MidiToMGBA from the releases tab.
• Run MidiToMGBA.bat
  • If you want to change the settings, open the .bat in any text editor.

TODO:

• Drop dependency on libmgba-sdl.dll exposing mSDLMain - instead, use custom SDL2-CS "platform."
• Find a good cross-platform MIDI library (atsushieno/managed-midi lacks good input recording).
• If possible, improve timing.

Note:
It ships with a devbuild of mGBA 0.7, split into multiple libraries, with the following changes:

• SDL platform's "executable" built as libmgba-sdl.dll instead of mgba-sdl.exe
• Entry point (function main) renamed to mSDLMain

miditomgba's Issues

NullReferenceException, Missing "Modified mGBA executable"

Main issue is the latest release crashes for me on launch (windows 10), log below.
Second issue is the release notes state the following, but these files seem to be missing (?)
