So every now and then I get emails from people regarding the application for the vita I developed a while back so I though I would official address the issue.
When I developed the application the PSM was in beta and you could install applications of the vita without having to buy a licence now that is no longer the case. Not long ago I tested the application using the build in emulator in PSM and it seemed to work fine. I am unable to test the application on the vita because I don’t have a licence myself and have no interest in purchasing one at this moment in time. Without a developer licence I’m afraid you can’t install anything on the vita.
