I've been using usb loaders for a while, but I've run into an issue I can't figure out. I recently purchased LEGO Harry Potter, but after installing to usb it won't work with cfg usb loader 57b7 no matter which IOS I tell it to use, but does with uloader 5.1D. Loading HP in cfg simply gives a black screen. I've matched the cfg loader settings to uloader as closely as I can, but doesn't help. Any ideas? uLoader settings are defaults (meaning its using IOS 222). I've installed Hermes 22x v5. In cfg I've set the IOS to 222-mload (I also tried 249, 223-mload, 224-mload, etc. with no luck). I also have waninkoko 249v19 installed w/ base 57. The last new game I got was SMG2, and I'm able to play that in cfg without problems. Thanks for the help!
