my carry flag conditional for subtraction operations is not right... somehow....

return ((~oldSrc + 1) & 0xFF > oldDst)

@Fuego try talking about it in plain english maybe?

what's the memory space you're working with? looks like 16 bit?

why are you doing & 0xFF? that's not gonna do anything to the number i think

Follow

@vahnj 8 bit - anding with 0xFF confines it to 8 bits

@Fuego oops off by power of one

ok so it's for the interpretation of the game - but if you're working in a larger memory space you have to keep in mind that the leftmost bit is supposed to represent being the negative number which can potentially be 0 in this case, right?

assuming i remember bitwise stuff right
