RetroArch backend

[japhib]

It would be cool to compile Pemsa with a RetroArch backend so it could be used on emulators that use RetroArch. There's another PICO-8 core called retro-8 that is available via RetroArch, but it's not fully up-to-date and I believe it doesn't emulate PICO-8 as closely as Pemsa does. For example, it uses floating point numbers rather than fixed-point, and I think some of the newer features are just completely unsupported.

I'm not sure what compiling against RetroArch entails, but I wanted to open an issue since it seems like a cool goal.

Yes, that would be really cool. I've done some quick googling around, shouldn't retroarch run sdl2 just fine? What is requried to get it running?

Not sure, I'll have to take a closer look at RetroArch docs. retro8 is the other PICO-8 emulator that currently has a RetroArch backend, so it seems like we could also use that as a resource and look how its compilation is set up.
