//  This emulator is preloaded with 16 CHIP8 ROMs.
//  You can add more at `roms.h`, provided you also add it to the `names` and `roms` array
//  (be mindful: games are stored in a 2D array; 8 items per page)
//
//  Choose a ROM on the Menu by clicking on the numbered button corresponding the ROM.
//  Press 0 to cycle through pages.
//  The QUIT button allows you to go back to the Menu screen and choose another ROM.
//  !!! CAREFUL: The buzzer might be too loud, adjust volume accordingly.
//
//  There might be bugs on some ROMs; IDK if this is a ROM issue or emulator issue.
//  For now I'm still trying to debug anything I can find faulty; but mostly it works!
