This fixes a 512 colour test cursor the devs have been using to test the hardware (and CSpect), it was a bug in the program but they're getting away with it due to this hardware check.
EDIT: Another minor change to fix the border colour.
- Port $303B overflow detection added
- Border colour should now work again. Paper palette offsets had shifted in line with the actual hardware
