If we look back at the various Gamescom videos I’ve uploaded, we could see that there is a special Application installed at the developer PS Vitas:
The Package Installer.
The App actually exists within the retail (that is your normal everyday PS Vita) PS Vita, but it is hidden.
If we use the following method, we are able to actually access and use the Package Installer application ourselves!

顺便说一句，最新版3.18的PSP模式漏洞游戏又出来了，有需要的抓紧。
激动的把VITA TV格式化，模拟神器我来啦。登录美服帐号，WTF，美服TV还没开放。。。。据说日服也有这个漏洞游戏

VITA TV破解掉你们不会反对吧

现在可以不通过PSN安装任意服的APP，以及试玩版了
