[Update: No longer happy. The timing is waaaaaay off in some sections.]
I'm good right now. Happy. Smiling.
I love my Vita, but I could never fully give my heart to it as Sony as they royally f*cked up by not having PSOne classics playable at launch. It took them forever to get their act together, and we're just now seeing the first titles come up as playable. Unfortunately, only a handful of titles are purchasable/downloadable right now, and one of my favorite games of all time, UmJammer Lammy, was not one of the available ones.
So I used the 'hack,' if you will. The workaround. The same thing I tried at Japanese launch while I creating our Vita FAQs, though it didn't work then. It works fine now. By downloading PSOne titles on the PS3, and then connecting the Vita to the PS3 to transfer titles, many more beyond the nine titles are playable. UmJammer Lammy was the first one I've tried as it is easily my most-played game ever. I never want to be without this game.
For the record, several more PSOne titles worked using this transfer method. Your results may vary.
