I found a weird game breaking glitch in Hotline Miami (first one) and part of me thinks that it could be useful for a CFW or LCFW exploit, but I'm not sure
(I want to know if there's a way to tell on my own if something would be useful or not, not neccasarily if just what I found is useful)...
Any updates on this?
The idea of putting it into an old cartridge is interesting, would like to follow with what you're doing though I only have a Genesis cartridge, but I could pick up a cheap SNES game if the size becomes an issue
