Hi there!

There is a bug in the 6502 when you're using any indirect addressing mode, where the adress is crossing a page, as in:

LDX #$FF
LDA ($00,X)

Will fetch the low-byte from $00FF and the high-byte from $0000

Basically such code can point anywhere. On the SC it can point somewhere else than on Z26.

Greetings,
Manuel
