Unity-based CHIP-8 interpreter / emulator

UCHIP - Unity-based CHIP-8 emulator

UCHIP is an implementation of the CHIP-8 interpreter in the Unity game engine. The code is structured so that this can be used as a general reference C# CHIP-8 implementation as well.

Implementation

UCHIP is implemented in two classes.

Chip8.cs

Chip8.cs is the main class, and houses all of the emulation code for the CHIP-8. ROM loading, input handling, drawing, and sound are not directly handled here.

Chip8MonoBehaviour.cs

Chip8MonoBehaviour.cs houses all of the Unity-specific implementations of the CHIP-8 code, and allows for a few features including custom colors and support for Unity's new input system.

Additional goals

• Implement CHIP-48 / XO-CHIP support
• Refactor Chip8MonoBehaviour.cs to streamline emulation process
• Ensure that Chip8.cs is Unity-agnostic so that it can be used in non-Unity projects
• Potentially split up Chip8.cs for better readability.
