I have a Wii NTSC with D2Pro9 f/w 2.3 util disk 1.7. This is the only mod is the chip. Console it at 4.2u. Just before updating to 4.2u / System update 41212 I was able to play PAL backups without issue. (brother updated) Now when I insert a PAL disk it spins for a few seconds and stops. There is no icon change on the Wii menu. If I use a USA NTSC it works fine. I f I use the Gecko loader I am able to swap disks and it works fine. I am guessing that this is due to 4.2u blocking other regions. I looked at the D2pro9 config and region patcher is enabled. 1) Is this is problem with the D2Pro9? 2) How can I play PAL backups again 3) How can I downgrade from 4.2u to 4.1U? I just want to go back to 4.1U. I cant find step by step on this as I am new to this I need this help. Thanks again!!!
