ROM Burning / Writing

ROM Burning is the process of writing information to a blank ROM Chip. Allowing PCB Games to read the information correctly to run the game. Chips can contain Game Sprites and Art, Sounds and Gameplay Allowances. If you have a Game with Graphical Errors, Sound Errors, or other general gameplay issues, it might be a ROM problem. 
Replacing ROMs can also completely change the game on the board. Some manufactures used the same PCB hardware for many games. With different ROM information that PCB could run many different games.
