RISC8Emulator is a software recreation of the CHIP-8 system, a simple computer from the mid-1970s primarily used for playing video games. Written in Zig, a modern programming language, this emulator replicates the architecture and functionality of the original CHIP-8, offering a unique experience for retro gaming and computer history enthusiasts.
- Memory: Emulates the CHIP-8's 4 KB RAM.
- Display: Simulates the 64x32 pixel monochrome display.
- Program Counter (PC): Manages the flow of the program.
- Index Register (I): A 16-bit register for pointing to memory locations.
- Stack: Utilized for storing 16-bit addresses for function calls and returns.
- Delay Timer: An 8-bit timer decrementing at a rate of 60 Hz.
- Sound Timer: Similar to the delay timer but emits a beep when not zero.
- Registers: Comprises 16 8-bit general-purpose registers (V0-VF).
main.zig: Entry point of the application, initializing the emulator.display.zig: Handles the CHIP-8's monochrome display.device.zig: Integrates components like memory and display.cpu.zig: Responsible for the CPU functionality and instruction execution.c.zigFile: This file is used to import the SDL2 library from C, facilitating graphical output and input handling.bitmap.zig: Manages bitmap operations for graphics.
- Zig programming language installed on your system.
- ROM Requirement: To run a game, a CHIP-8 ROM file must be added. This emulator does not come with any preloaded games, so you need to provide your own ROM.
- Clone the repository:
git clone https://github.com/alvarorichard/RISC8Emulator.git- Navigate to the project directory:
cd RISC8EmulatorExecute the main.zig file with the Zig compiler to run the emulator:
zig run main.zigor just run :
zig buildContributions to improve or enhance the emulator are always welcome. Please adhere to the standard pull request process for contributions.
