The individual game Zippy Race uses Horizontal Mirroring and has a bug that causes inadvertent CHR-ROM writes, which on this multicart of course become CHR-RAM writes. On emulators that fail to emulate the CHR-RAM write-protect, the "P" of the red "1UP" script on the right side of the screen becomes corrupted once the race has begun.

Honestly, I'm quite surprised that the pirates cared about such small details. :)
