v0.0.6 OnDraw render mode is now working, and it can take multiple drawCalls before rendering. This can decrease blinking in some games. But some other games have no-draw loops, which can freeze some browsers. Fixed overflow of sum opcode, added delay configurations.

v0.0.3 Keyboard, fonts, more opcodes, vF register, more configurations, bug fixes
v0.0.2 Every string to number convertion (except debugger) has been re-implemented as number only. New rendering engine, draws a full frame instead of drawing every single pixel. A lot of ROMs are loadable now.
v0.0.1 This is my first attempt of recreation an emulator, without looking into other people's code. Here are a lot of things that are done wrong, and the only working ROM is MAZE. Also, this project is using web components and JS imports, so you need a modern browser to run it.
