noticed an issue with the v7 patch. The game seems to be stuck after the "System Data" message if I patch the eboot with "EbootOST.bin.v05.xdelta" but works fine with "EbootEVO.bin.v05.xdelta"
staying at that firmware wont give you any advantages, IMO.
just follow the guide https://github.com/Plailect/Guide/wiki and you wont have to worry about emunands and such.
