Not much improvement from the little testing I have done. Tried a few Different base IOS for 249 and 250. It breaks Triiforce and ISO forwarders. My games load faster with Rev19 250 or even Hermes 222/223 (Rev 17 would be fine but I am using FAT now). So I am sticking with my Rev17/Rev 19/Hermes Combo for now. Does everything I need it to.
