Apply a correction on enemy movement for PAL
We cannot just "inc"/"dec" for enemy movement, but we have to apply an
overstep on PAL every 5 frames in order to be equivalent to the NTSC
version. This has been abstracted away on a macro that just does
"inc"/"dec" on NTSC, but does this proper "adc"/"sbc" instructions with
a helper memory region which is updated every 5 frames.
