VitaShell v1.51 is just about fixing existing bugs on VitaShell v1.50, so I'll add changelog for both version, since new stuff is coming on v1.50 :VitaShell is an alternative replacement of the PS Vita's LiveArea. It offers you a file manager, package installer, built-in FTP and much more. This homebrew was an entry of the Revitalize PS Vita homebrew competition and won the first prize. HENkaku's molecularShell is also based on VitaShell.
