Also, In the game, there many areas of corruption - mostly at the end of a level. This is noticeable in Pirate Treasure too..

I fixed an index out-of-bounds access when reading the pens in r31555 - did this help?

Nope, r31555 doesn't make any difference.

The old leprechn.c driver had video ram readback hooked up through one of the VIA ports, this was removed (intentionally? accidentally?) when gameplan.c and leprechn.c were merged. I've put it back (r31560) it doesn't fix the issue but it makes *some* difference: instead of leaving black holes in the rainbow, a trail of images of the character is left instead. I think someone more familiar with the 6522 VIA needs to take a look at this to determine what's missing (our VIA implementation has changed a lot since 0.115)

not sure if it's related, or has always happened by piratetr in the same driver seems to crash after a certain point (which isn't difficult to reach)
see

&t=2h26m55s

if they're using the 6522 VIA stuff as some kind of 'protection' I guess it could be related.

just jump to 2h26m55s because apparently the auto embed thing here mangles the link entirely.

could just be a game bug I suppose, but it requires minimal skill to get that far.
