Select a ROM and start playing! My personal favorite is Tetris. :)
CHIP-8 uses a 4x4 pad for controls, the tables below show how keys are mapped on the keyboard. Since every game has different controls, you will have to discover them for yourself.
| 1 | 2 | 3 | C |
| 4 | 5 | 6 | D |
| 7 | 8 | 0 | E |
| A | 0 | B | F |
| 1 | 2 | 3 | 4 |
| Q | W | E | R |
| A | S | D | F |
| Z | X | C | V |
This is a basic CHIP-8 emulator implemented in JavaScript (or TypeScript rather). I followed a high-level guide which was a good middle-ground between challenging and fun.
