If all tests fail on screen "f?" will be shown (corresponds to 6 failures) and the bitmap %00111111 ($3F = '?') There are 6 tests (bit 5 to bit 0): STX $FFFF fails in 16 mode for X/Y if wrapping to location 0 STY $FFFF fails in 16 mode for X/Y if wrapping to location 0 LDX $FFFF,Y fails if wrapping to same bank LDY $FFFF,X fails if wrapping to same bank TRB $FFFF fails in 16 mode for A/M if wrapping to location 0 TSB $FFFF fails in 16 mode for A/M if wrapping to location 0 -------------------------------------------------------------------------------
