TODO

• Remove the mutex, or replace it with std::mutex

• see if smb3 and punchout work in vnes

• save memory to localstorage/indexeddb

• tetris has no backgrounds

• Try using opengl for the screen to see if it makes painting faster.

• make fps show in html

• Make it so the emulator can be restarted without reloading the page

• Add gamepad support

• make the emulator easy to embed in other web apps by having hooks for all gui buttons

• Make it not cache the wasm file, even after shift reload

• Is there a way to check if running asm.js instead of WebAssembly?

• Shrink wasm file by removing complex libraries
