Here's something probably useless, but was useful for me. Creating short term delays :)
* = $1000
SEI
DELAY LDX #$00
LOOP2 LDY #$00
LOOP1 INY
BNE LOOP1
INX
BNE LOOP2
RTS
To make things interestingly wild, or silly. Before LDX #$00 add the following:
JSR DELAY
INC $D020
JSR DELAY
INC $D020
JSR DELAY
INC $D020
JSR DELAY
INC $D020
JSR DELAY
INC $D020
JSR DELAY
INC $D020
RTS
