Ok, so my idea is to simply replace the Kiddy Kong sprite with Donkey Kong's sprites.
I've been told I would need to do this manually with a hex editor, lots of pointer calculation, and intermediate asm knowledge.

I know how to use hex editors and I'm not quite ready to jump full on into asm yet but, what would be a good place to start with pointer calculation? I know what pointers are but how do I use this information to my benefit? Could anyone recommend a good tutorial or learning aid on this one? Thanks!
