So I found my Nintendo DS Lite just now after maybe 4 years of not playing it and I realised I still had my R4 cartridge. When I opened it up, all it just said was "loading". This made me venture in different ways to fix my R4. I've tried Wood and YSMENU and they've worked, it's just that when I try to load a game (such as Pokemon Platinum) I just get a double white screen. I'm pretty sure I've downloaded all the most recent kernals for Wood and YSMENU but the game doesn't work on either interfaces. What could be the problem?
