Hey guys just updated the USB Loader to r830. And guess what NSMB NTSC works like a dream. You do not need any patches, srubbing or any thing else for that matter. Just update loader to r830, rip NSMB NTSC to HDD and enjoy. I have a 4.2U. So I do not know if this will work on any other versions. Just thought I would give a heads up to save some time, headaches, and trouble. Peace.
