Convert .gbs to .mid?

[tajmahal]

Hello,

I just noticed that VLC can play back .gbs (GameBoy Sound) files, which is awesome!

I now wonder if there is any way to have VLC convert them to MIDI files. Can VLC do this?

Kind regards,
Tobias

No and I'm not sure if that's even theoretically feasible.

Well, this tutorial suggests a rather cumbersome way to do it (by having a so-called "rerecording emulator" run a Lua script which is supposed to output midi of what the emulator is currently playing back):

I haven't tried this myself, but from reading the tutorial, it sounds like it might work. So I guess, while VLC is unfortunately not able to pull this off at the moment, it is indeed theoretically feasible.

I just tried the process described in the tutorial above, and I got a pretty accurate MIDI file out of it. Instruments weren't correct, and the delta-time unit wasn't aligned to something sensible (e.g. a quarter note), but the actual notes themselves were just fine, and properly split up into individual tracks.

So this is definitely doable! (If someone is willing to implement it in VLC. )
