Delay code

Shortest possible CPU code that creates N cycles of delay, depending on constraints.

All branch instructions assume that no page wrap occurs.

Explanations on the requirements:

  • @zp_temp means you have a zeropage address that you can write random data into.
  • @rts12 means you know a memory address that contains byte $60 (RTS).
  • @rts14 means you know a memory address that contains a harmless 2-cycle instruction that fits your constraints (such as CLC, LDA #0, or NOP), followed by RTS.
  • @rts15 means you know a memory address that contains a JMP that jumps to another location that contains RTS.
  • Alternatively, @rts15 means you know a memory address that contains a harmless 3-cycle instruction that fits your constraints (such as LDA $00), followed by RTS.
  • @A, @X, @Y are local labels.
