Someone's developed a hack/exploit that allows previously unsupported PS Vita games to work on the PS Vita TV - one of which is Wipeout 2048, and damn, does it look awesome on a big screen. I think I may have to get one of these now. Someone's uploaded a video of it working:
Sounds like a few people haven't been so successful in getting it running, I don't know if it's something to do with the specific firmware that's installed in the system or what, but I might have to try and find out a bit more about this before taking the plunge. It begs the question though, if Wipeout runs so well on the Vita TV with a minor hack, why isn't it officially supported? Madness.
