I missed this variant before: You should be able to do INC $30 for a
two-byte five-cycle non-destructive delay. $30 isn't used by the TIA as a
write register; as a read register, it returns the same data as address
$00, which is just a collision register and reading it does no harm. As
long as you're not using a cart that does bankswitching on that address, it
should work. (this is obviously 2600-specific and not 6502-generic, which
most of the others were)
