WebAssembly support

[nelsonxb]

Hey there. I'm curious if anyone has tried running mGBA under WebAssembly, since I might have a use case for such a thing (in the somewhat distant future). If so... how did it go?

If not, I'm keen for a bit of pioneering (though I'm pretty busy over the next couple of months, but should have time after that).

Is anyone able to forsee any potential issues off the bat?

This is actually on the roadmap for mGBA 0.8, but I haven't tried it yet.

Sweet! I'll follow up if I get the time to look into it. I'm comfortable with C myself, so if I get to it first then I'm happy to submit patches if need be.

Also, would be stoked on this! 😀 Let me know if you need help on the JS side of things!

Just a tip if someone arrive here by google...

I'm wrapping the emulator on web app gbajs into a React component, so you'll can embed it on your project.
I'm doing it because I need a GBA emulator that runs on browser, and gbajs was the unique option that I found.

I think that on the next weeks I'll launch this package, react-gbajs.

Edit: package published 🎉

I have this mostly done but I'm still missing a decent frontend.

@endrift Is there a branch or a commit I could test out :) I don't need much of a front end. Just want to mess around. What's the performance like?

Branch is here: https://github.com/endrift/mgba/tree/feature/wasm but it's been a while since I toyed with it so I don't remember.
