I know that USB Loader GX has a 002 fix that has worked for me (on Punch Out). It's about the only thing I can suggest that I know might help. You can find USB Loader GX via google, or right here:Downloads ?(USB Loader GX)?
Waninkoko's cIOS 249 should do you good, although for a game this recent it might pay to make sure you've also got cIOS 38 rev13b (Waninkoko's most recent cIOS) installed, which you can also download at the link above.
Buying games retail is always a viable solution if the hacks don't work... it seems like there has been a lot of issues with wii sports resort running but I think many have gotten it to work so if you want to fight for your $50 keep on trying! ;)
