Chip-8 Emulator in RUST

Yet another Chip-8 emulator - this time in RUST 🦀. WHAT A CONCEPT.

The spec was based on the brilliant document from Cowgods neato specification

Todo

• All instructions (kinda)
• Basic Memory structure
• Basic execution of instructions
• Loading ROMs from disk
• Implement the rest of the instructions
• Implement a display
  • For the emulators output
    • Able to write sprites from arbitary memory locations to display using drw instruction
    • Able to use built in sprites for hexidecimal numbers
  • GUI for viewing the internal state of the CPU
    • Semi-completed. Currently able to view internal state of Memory/Display/CPU via DebugDisplay.view_state()
• Support for the timers
• Support for the Chip-8 16 key keyboard
  • Currently broken, any ROM that tried to read keyboard state will cause the emulator to panic
• Execution control
  • Ability to step through execution?
  • Modify memory locations at runtime?
• Fancy GUI?
• Perhaps support for a basic assembly language? 👀
  • Implemented a disassembler for Chip8 ROMS (see Chip8-asm)
