The flags and rocks occur in random places at the start of each wave. Often times they occur near to each other in a row, something I was going to avoid to reduce overall flickering

If you can make it work with 1 map in 4K, consider making it a 16K game so you can have all 4 maps. Each bank of 4K would contain a complete copy of the program code, but a different map.

Do you have MAME so you can test against the original Rally X & New Rally X? I can send you the ROMs if you need them.

Hi Darrell,

Thanks for the info, I wish I had done the posting earlier, it would have
saved me a job finding the map and converting it for the VCS.

I eventually found all 4 maps (but due to space I'm only using map 1),
although the one you supplied also includes the location of flags and rocks
which I did not have thanks, the scroll is coming along nicely currently 4
screens high by 2 screens wide. I'm using a mirrored playfield, and ignoring
PF0 to gain some cycles.

I have a lot to understand about the 2600 architecture and more on
optimising 6502, but that is what make this stuff fun.

Still there is a very long way to go, and I have a feeling that I will be
seeking the expertise of this list during the process.

Everyone ... Thanks for the encouragement
