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.

USB Loader GX loading channels slow and not showing all covers (Some other issues I will touch on aswell)

Hello, This is my very first thread on this site and I am not entirely new to homebrew but I'm at a very basic level of it (youtube tutorials and wii hacking site for most things). I have had this wii for awhile and recently tried using it again only to find quite a few issues. Currently the issues are the ones in the title of this thread aswell as trying to replace the cIOS in 248-251 with beta1 but it only says net_init even though I have the wads on the root. I have been trying to fix this with my brother and we think the cIOS are the issue because we have 2 wiis here, same sd card size, model, and contents and same goes for the hdd. Yet even with everything the same USB loader gx only works good on one wii (with both sd cards and hdds) so we dont think either of those are the problem. If anyone has any advice they could offer it would be greatly appreciated. Some quick info: The working wii has slots 248-251 as beta1 and a slightly older version of USB loader gx but it works well so I havent changed it. The broken wii was having an issue where the channels in usb loader would all be one game (for example all would appear as pokepark) so we updated usb loader and the cIOS to beta3 but that did not help. Eventually by reverting to the version of usb loader thats on the working wii, the channels started loading properly. The only issues now are the ones I mentioned in the main part of the thread so now I don't know what to do from here.

Hello everyone,

I'm working on an expansion mod for the Wii version of Mario & Sonic at the Olympic Games (Beijing 2008). The goal is to fully integrate the many cut rival characters into the game, making them playable and unlocking them through new challenges.

Features:
- Expanded Roster: Adds Jet, Rouge, Omega, Eggman Nega, Silver, King Boo, Dry Bowser, Dry Bones, Big Bullet Bill, and Donkey Kong.
- Restored Content: Re-integrates leftover assets and data from the game disc.
- New Unlock Conditions: Unlock characters via Circuit Mode, Mission Mode, and new Emblems.
- Character Emblems & Crowns: Adds new collectibles for each rival.
- and more!

Progress:
- Successfully loaded Jet into the 400m event (with working animations).
- Identified the character ID table in the main.dol file.
- Created a draft of the new roster layout.
- Extracted the game's main data archive (cddata.dig).

Current Goal:
I'm currently working on extracting the model files for the character models to create new icons for the roster.

Any advice or help would be greatly appreciated!
