Peel buffer overflows on level 13 #70

Closed kieranhj closed 6 years ago

kieranhj commented 6 years ago

Final boss level - lots of falling floor pieces drop from the ceiling simultaneously. It is quite easy to overflow the peel buffer - just run across the second screen. Current buffer size &A00. Might need to special case this level maybe?

Increase peel buffer to &B00 and can still overflow when runnning & jumping at the start of this level. :(

Increased this to &C00 (and also increased maxpeels) to accomodate this and seems OK from testing. Had to move the full fat MODE2 plot routines into an overlay loaded alongside the Princess screen to save 2 pages to make room for this!
