I just completed New Super Mario Bros. so I thought I'd play the rom hack Newer Super Mario Bros which I'd heard good things about. Problem is that it boots to a white screen. I had this issue with the original game as well but there, the fix was as easy as using the European version of the game instead of the US version. With the patched rom though, it seems to boot to a white screen all the time.
Have any of you been able to play Newer on the DSPico and if you ran into the same issues, what was your fix?
