From snkysnake: REX 4.21 is a go ^_^ just did it, only problem with this I see is that when ReAct resets itself after doing its thing the PS3 message pops up saying the PS3 was shut down improper and it needs to check file system.
That takes about 2-5min O.o hmmmm any way around that ? If not, I honestly don't care its not that big of deal to me.
