Hi, all, I am somewhat new to posting in this forum but I've gotten a lot of good info from here over the years. I've spent the whole week trying to solve this problem but haven't found an answer yet. I've had my original 4.3U Wii softmodded for a long time and using USBLoaderGX to play games from a usb drive. I've never had any problem with games as they were originally released and I mostly play Mario, Skylanders, and Wii Sports. This is my first time attempting to play modded Wii games, specifically Mario Kart Retro Rewind and NSMB Retro Remix. I didn't know about them until a couple of weeks ago and I'd really like to try these. For MK RR I've followed the tutorial here several times to patch my iso file but I can't get the resulting file to work. No matter what I try it either returns me to the Wii home screen or hangs on a black screen. NSMB RR is a pre-patched .wbfs I found online instead of patching my iso and I get the same result. My MK and NSMB isos are ripped from my own discs, and for MK I also tried patching an un-modded .wbfs found elsewhere, but still no joy. I've tried with the channel forwarder and directly from USBLGX. I've tried running from two different flash drives and two different SD cards, all formatted as FAT32. And I've tried two different versions of USBLGX, 3.0r1281 that I've been using for a long time and a recent download of 4.0r1283. The same usb drives and SD cards have no problem playing un-modded games such as original Mario Kart or Wii Sports, including with both USBLGX versions. Is there any cios that is required for modded games to work? I have an old file from the syscheck app if you need to what cios I have installed. My Wii was softmodded with LetterBomb and Hackmii 0.8. I can say that I have d2x-v10-beta52, and since this syscheck report I've only added PriiLoader 0.10.0 and updated Homebrew Channel from 1.0.8 to 1.1.4.

Stop using MyMenu and use ThemeMii instead, it's much better.

omg thank you so much. I got it working in a second with no help from anybody. Thememii worked better than I expected.

Thanks for the help! (Is there any way to close this thread now?)
