Maybe - I’m really bad at explaining things so I’ll probably just get more specific than I have to
Basically, there’s two menus I’m referring to - the “play game” menu and whatever menu you have before that (I’ll just say library). Without starting a game, I can go to and from each menu with one button press. If I start and exit any game, I return to the play game menu, but in order to go back to the library menu I have to press B twice; it acts like I’m closing an invisible menu or something which could be the black screen in your case.
In reality, this bug isn’t anything major - I just wanted to know if anyone else was experiencing it and/or if anyone knew why it was happening (maybe someone with CSS experience could make a plugin to fix it)
Are these roms/hacks that aren’t in the roms megathread? I’d have to assume most of these already have duplicates somewhere else just by nature of them being put online
