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
, orNOP
), followed byRTS
. - @rts15 means you know a memory address that contains a
JMP
that jumps to another location that containsRTS
. - Alternatively, @rts15 means you know a memory address that contains a harmless 3-cycle instruction that fits your constraints (such as
LDA $00
), followed byRTS
. - @A, @X, @Y are local labels.
