This is only a homebrew of course but what they've done to it is amazing. The game is a wifi homebrew game so you actually create an account, you have a friends list that you can message and chat with or you can just play against random people, etc. Now there has been another Triple Triad for PSP, but it only let you use level 1 cards, it'd end up crashing alot, you couldn't customize your deck, couldn't play against other people, etc(so in short, it sucked.)* Premium Deck disagreements
* Management and deck use in match
* Fixed exit when pressing HOME
* Increased AI speed in game
* Reduced downtime in any game
* Adapt to new images of the game
* Varied speeds entry cards in the lot
* Entrance of the cards in a group game at a time
* Changes to position the numbers on the card during the match
* Fixed rule COMBO
* Presentation of the game before loading

Watch the Youtube video of it and it may just interest you(the Youtube video is in 2007, which shows just how long this game has been in the works.) Now if only Wololo/Willow implements homebrew on Wagic: the Gathering(Magic: the Gathering.)
*edit*
Oh yeah. I also just downloaded it, so if everything isn't implemented then sorry. But I'm assuming from the video that it's done(will try it out tonight to say or not.)
