i have read a few different threads and i am still confused about the ramifications of updating to firmware 3.3Uv2. i am running firmware 3.3Uv1. i currently have HBC beta9, a Cyclowiz modification, a bunch of installed wad files, and patchmii + libdi installed for DVD playback. i don't use any type of backup loader. is it safe for me to update? what are some of the problems i will face if i update with my current setup? what are the benefits of updating?
