PlayStation Vita developer SKFU has updated his PS Vita Firmware xTractor homebrew application to version 2.01 and included a Linux build.
To quote: PS VITA Firmware xTractor 2.01
Linux version compiled and attached below.
I just updated the PS VITA FW xTractor, changelog is attached below.
The 2.00 version had a problem setting the filenames correctly as the 1.0+ updates have different files than the older ones. Anyway, enjoy...
