Fenix Emulators

Is there such a thing as fenix emulators, meaning say for example a Nes emu written in Fenix?

nope. sometime ago i started coding a GB emu... but then realized that fenix is by no means as fast as necessary...
perhaps it can be done, i don't know

I bet you could do a Chip8 emulator/interpreter using Fenix.

There's not much to running those games at all. :P
