Hello, I have a problem i just installed newersmbw but the game crash after the message that says i have to go save peach. The wii stops flashing and there is a black screen. Can you help me please? I don't know what to do

I've never encountered this crash but I would recommend deleting all the NewerSMB files then re-downloading the whole game entirely. That should hopefully fix it.

Thanks dude, I will try this

Hello, now I managed to access the map after reinstalling the game but some levels crash. How to solve this problem ?

I'm not sure I've never encountered that problem. Are you playing with riivolution or with a rom?

I play with riivolution

crashing levels are 1-3 and 1-7

Yeah sorry I have no other ideas to fix it other than deleting the entire game, that's important. But you could also try using a different SD Card. If you use a SDHC card try using a non-SDHC Card (2GB or less), or vise versa.
