Suggestions of things to do:

  • Make it (more) functional
    • Encapsulate all of the stateful data as a type that can be filtered through each iteration/tick - meaning it can be immutable
  • Make sound work
    • The Sound Timer (ST) is implemented but isn't doing anything.
  • Make more use of the DOUBLEBUFFER
    • It's used only for performance at the moment to know which pixels/cells to draw each tick
    • Could be used to draw when pixels/cells are redrawn (the flickering of sprites I think would be solved)
  • Add DEBUG UI
    • Add more UI where the game screen becomes just a small part of the emulator window
    • Use additional space to give graphical representation of the Memory, Registers and where the PC is pointing in memory etc.
