Beta 7 and 8 worked a lot better than when I tried them before. Beta 7 was able to at least start all of the games, and beta 8 only gave me that tmd error on one of them. So does this mean it's my devices not being fully compatible with the NAND emu? LIT gave the exact same error on both SD and USB NAND, though, wouldn't that kind of a strange coincedence if it's supposedly just a device problem?
I wouldn't be surprised if the hard drive wasn't fully compatible though.. I tried to get it to work with USB loaders and cIOS249 many times in the past and it never worked, but recently I tried it with Hermes' cIOS222 and uLoader and to my surprise it worked, so I thought I would try it out with TriiForce, not really expecting any results. I'm pretty pleased that it even worked at all lol.
Let me know if there's anything else I can do/anything I can test to help out.
