USB Loaders: Games fail to function after launching
My Wii is softmodded on 4.3U, cIOS 222 rev4. I have Homebrew Channel working perfectly well, and can easily launch custom wads (such as NES, SNES emulators) from the official home screen. I just can't launch them from an SD card. (I install my wads using MMM (Multi Mod Manager)). I have a channel for Wiiflow from where I launch it and select a game to play.
When I select a game to play, it launches perfectly fine, then at some point it fails. It varies from game to game. For example, in Donkey Kong Country Returns, I can pretty much do everything until I actually enter a stage. The first issue I notice is that the overworld (the map from where you select a stage to enter) has no music. Sound effects are there, though. Then when I select a stage, the screen gets slightly darker and the game freezes. Twilight Princess gives me a black screen after I press A + B on the title screen. Most games just fail to load after the wiimote strap warning screen.
I thought the issue was WiiFlow (v2.1 r228, the loader I use), so I tried uLoader (v5), and got the EXACT SAME results (game loads, freezes at the same point) (EDIT: I just tried USB Loader GX, the latest one as of 18/09/2011, with the same results) I then thought the issue was my hard drive, so I tried using a different one (using the same USB enclosure), and I got the same issue. I then thought the issue is my cheap eBay enclosure, so I used an 8GB USB stick, and I get the EXACT same result, so I figured the issue must come from the Wii settings, or the Wii itself.
It was working perfectly fine months ago. I stopped playing with my Wii for a little while because I simply had no time. I can't say my kid brother didn't play with it, but what I mean is, my wii's hack settings remained unchanged for months and before my "wii break" it was working fine, after my "wii break", nothing works... (all of the mentioned games above worked 100% fine before). It's almost as if it just suddenly stopped working for no reason, but that's impossible so I'm ASSUMING my kid brother might have tinkered with it (although it's VERY unlike him). I'm still on 4.3U, and all of my homebrew apps work fine. The games even load! (for the most part), but it's as if the system is not loading anything off the HDD\USB Stick after the initial intro.
Is there anything I can do to troubleshoot? What settings must be set to what in order to make sure the game loads correctly with a USB?
