firefly-chip8

CHIP-8 emulator for Firefly Zero.

Usage

First, create config.txt. For example:

speed=14
2=1U
C=2U
D=SN

This config tells the emulator:

• speed=14: run 14 instructions per update
• 2=1U: read CHIP-8 2 button from Firefly up of the first peer.
• C=2U: read CHIP-8 C button from Firefly up of the second peer.
• D=SN: read CHIP-8 D button from Firefly N button of the shared peer (pressed if any peer presses it).

Include the emulator, the ROM, and the config in firefly.toml:

# ...

[files]
_bin = { path = "main.wasm", url = "https://github.com/firefly-zero/firefly-chip8/releases/latest/download/main.wasm", copy = true }
main = { path = "pong.ch8", copy = true }
config = { path = "config.txt", copy = true }

Now you can ff build and play the game.

If you need to update the interpreter to the latest version, remove main.wasm from the project root and ff build again.
