You got a dump of a Vita game and you are unsure what version of Vitamin dumped it? Here is a quick way to tell.
Rename the VPK to ZIP and open file and look at the CRC of steroid.suprx file
1.0 dumps: The CRC32 is 4FD25E74
1.1 dumps: The CRC32 is 6F6F71BB
2.0 dumps: The CRC32 is 1DF8B729
I am hoping this info is added to vitaorganizer soon.
