I want to do a Mike Tyson's Punch Out! Hack

Okay, I'm feeling extremely impish & I want to attempt to do a hack of Mike Tyson's Punch Out! Replacing Mike Tyson with Mister pound for pound douchebag of the world Manny Pacquiao :PHowever I got no clue as to how to make a game hack & TileLayerPro (TLP) seems to be only useful for editing sprite's looks, not their color according to the tool's beginner's guide. And I have no clue doing hex editing to change the game's text. I really want to rip on Manny Pacquiao & make him shut the eff up, even only in a virtual manner. I hope you guys can help me out on this one :)And for guys who visit RHDN, yes I did post this there too ;)EDIT:Terrific!One person replied to my post on RHDN & it's the cold hearted resentful one pfft!Can't he just like give me a good link nicely :(

Was going to say read the various tutorials on RH.
