Hello all, newbie here!
I've always been a fan of the old bootleg/romhacking scene, particularly for SNES and Genesis. I have a question regarding title screen hacks. In the 90s, a team by the name of Twin Eagles Group would hack said screens and replace them with compressed images. (Examples below.)

I've wanted to give this a try for my own personal projects, but in all honesty, I don't have the know-how or experience to wrap my head around it. Would anyone here be able to give a step-by-step tutorial on how this could be done? Any help would be greatly appreciated!
