After experiencing the Wii resetting itself while trying to load Wii Sports Resort i began to research this error and after testing various methods i found this to work perfectly. Firstly i was testing a Wii that i had just performed the 4.2 Safe Firmware Updater on and using NeoGamma R8 beta loader. I installed IOS55-64-v4633 but this did not work although it might have contributed further down the line I'm not sure. I then downloaded the alternative RTZP01.dol (searched Google for "megaupload rztp.dol" for Wii Sports resort and placed it on an SD card in the folder NeoGamma Inserted the game disc and selected Neogamma, at the options screen i then chose -> Config options -> Alter. .dol and selected SD Returned to main menu and selected Launch game on dvd. Then the game will play the 3min video of how to use the motion controller. When finished playing the Wii will reset itself. DON'T WORRY! Now load game through NeoGamma as normal and all should work fine. The only other thing i did whether or not it makes a difference i am not sure but i copied an existing game save of Wii Sports Resort from another machine onto the one i was testing. Steve.
