I have an error running New Super Mario Bros and Muramasa Demon Blade using USB Loader GX. The only good advice I could find was to update my rev on USB loader to the most recent (rev815c), since this has a 002 fix, but I still get the error. Any ideas to fix an 002 error?
Go into the setting of your loader and enable the 002 error fix.
