Known Bugs

  • The program counter doesn’t reset to 0x0100
    • To fix this, hold down the Reset button attached to the program counter and press Ctrl-T twice to advance the clock. This should set it to 0x0100 and program execution can begin.
    • If your ROM contains absolute addressing then you’ll need to manualy zero-pad it to start at 0x0100
