What is do-able?

Platter can be used to play (seemingly) any chip-8 rom, visualize it, correctly report all values etc.
No Chip-8 roms have been found that break the Guacamole.
All valid Chip-8 assembly can compile.
Many pre-processor commands are supported by jalapeno, unlikely that more will be supported.
Any wav file can be used for the sound timer.

Known Issues / Missing Features

Keyboard inputs are not configurable in platter.
Keyboard input works in a 'unique' way. All inputs are static and reset after 0.5 seconds, this allows (kind of) for two simultaneous key presses in platter.
No confirmation that your key press was registered (aside from game change) in platter.
Only one resolution available in platter
Blackbean does not warn the user if an instruction edits VF.
No support for the 'original' shift behavior in guacamole.
Jalapeno does not support mode/option settings in the file. It just strips them.
