Stage2 is approaching: Redsteel2/WiiSportsResort is now working with Motionplus&Nunchuk, and the controls for the nunchuk are working now as well.

Apparently, motionplus games are very strict on calibration data checksums, they don't like invalid/0x00'd checksums(this is trackable via 0x01 writes to the active extension register at 0xA400F3). I'll keep all motion plus related stuff that I've discovered on my blog: http://snzgoo.blogspot.com
Next time I'll fix the disconnects, which are most likely caused by the sent motionplus empty/dummy data.
So stage2 might come sooner than u guys thought. Let me hear u scream;)
