I've just completed an update from 4.1 to 4.3 using ModMii. Everything went OK with no errors. I'd upgraded as Disney Infinity didn't work (it's the original disc). After updating to 4.3, Disney Infinity worked, but it's stopped Neogamma from working (v9.56). When launching Neogamma and trying to launch as disc, I get an error saying 'DVD-R + no CIOS'. I read somewhere that if I re-installed DX2 that would sort that error out. I re-installed it from the WADs on the ModMii SD card and then trying again. That worked. But then I tried Disney Infinity again and it said it needed a system update. If I install the update, Disney Infinity works, but then it breaks Neogamma again - and the cycle continues. Any ideas?
