This is my setup: PS Vita 1000 at 3.60 Henkaku Enso with 16GB Vita Memory Card and SD2VITA 200GB.
What I did: I removed my ux0:tai folder from both my memory card and SD2VITA, moving it to ur0. Afterwards, I wanted to edit my config.txt so I moved it to my computer, edited it, then deleted it...
I like that games can be fixed after the fact, hate that it's being abused via beta tests... And DLC... I was a 7800 owner back in the day and loved Impossible Mission, turns out I couldn't beat it because it was actually impossible lol
