Project Idea: Browser-based WASM RetroArch with JIT support

[RetroGameDeveloper]

Currently most browser emulators are compiled from native code (C/C++) into Web Assembly (WASM) without any support for dynamic just in time compilation (JIT) at runtime.
This means that systems such as 8-bit and some simple 16-bit systems tend to run at full speed (e.g Game Boy) but more advanced emulators are just too slow.

What if we could get JIT working on these slower emulators so we could have near full-speed emulation in the browser.
