• src/main.zig: Contains the main application loop, initializes the CPU and the graphics interface.
• src/cpu.zig: Defines the CPU of the Zetta-8 virtual machine, its registers, and instruction set.
• src/gpu.zig: Includes functions that use Raylib to draw the video memory (VRAM) to the screen.
• src/asmref.zig: Holds references to the assembly instructions used by the CPU.
• build.zig: The script that defines how to build the project and its dependencies (Raylib).
