this program is largely incomplete and not in a presentable state.
please be mindful when sharing it.
however, feel free to copy any snippets of code you find useful.

usage:
0. edit config.lua as you please
1. open FCEUX 2.2.3
2. load Super Mario Bros. (U) (CRC32: 3337EC46)
3. open a new Lua script window (it's in the File menu)
4. browse and open main.lua

TODOs: (that i can remember right now)
- normalize `for i=a,b` code style
- normalize and/or embed sprite type inputs
- settle on a network architecture
- compute how many input neurons the network needs instead of hardcoding
- add some detection for enemies later in the game
- fix cfg.enable_overlay (smb.lua doesn't see it being changed)

naive:
- learn any combination of buttons, starting from title screen
- learn to run network without frameskip
- learn other games
