mario kart, smash brothers problem
I have a NTSC-US d2c Wii with firmware 3.3u. I also have a D2pro9 modchip installed with a recently updated 1.7 spi. Whenever I try to play some NTSC-US games, it tries to perform a Wii system update, the games include (final fantasy chocobo's dungeon, super smash brothers,mario kart ).
When i used the 1.7 utility disc to turn on the wii system update blocker for all regions, i was able to play final fantasy. But trying to play smash brothers or mario kart appears to crash my Wii, where I can see the title screen of the game, but then the game crashes with a black screen, and my wii-remote flashing its LEDs.
Can anyone confirm that it is safe to perform this Wii system update, or to update the firmware from Nintendo to 3.4U?
Any help would be appreciated.
