I know you will contribute more for the SNES - because it's an actual challenge :) All the other stuff? Everyone does it.
The SNES homebrewers are quite the nice and enthusiastic little community, feel free to ask the guys to help you with scrolling or whatever. I am sure someone will help. They also helped each other a lot during the last SNESDEV Game Jam in 2021. Goldlocke, Svambo and bennysnesdev are very competent and helpful.
