Yet another Rust implementation of the Chip-8 system.
This is a basic implementation of the Chip-8 system, used as a "first-step" into making larger-scale emulators.
This implementation passes all test ROMs I could find, and plays games such as PONG / Tetris without issue. The only caveat is that the display to terminal can scroll / flash a bit, and my goal in this project was the emulation itself, not the nuance of terminal output.
Using Cargo...
cargo run PATH-TO-ROMThe keymap used is the left-hand-side of a standard QWERTY keyboard, but can be remapped in src/main.rs.
The default keymap is:
+---+---+---+---+ +---+---+---+---+
| 1 | 2 | 3 | 4 | | 1 | 2 | 3 | C |
+---+---+---+---+ +---+---+---+---+
| Q | W | E | R | | 4 | 5 | 6 | D |
+---+---+---+---+ ---> +---+---+---+---+
| A | S | D | F | | 7 | 8 | 9 | E |
+---+---+---+---+ +---+---+---+---+
| Z | X | C | V | | A | 0 | B | F |
