Tipster has just released a new version of his homebrew ZIP/RAR unzipper application for PSP, which can be run as a standalone unzipper, or as a plugin in iRShell. This tool can be very helpful if you find yourself downloading .RAR files from the Internet directly to your PSP, and don't have access to a PC to decompress and place on your MS. Great work Tipster!
New features/fixes in v0.3 include:
- .RAR support (including RAR3); passworded .RAR support as well.
- Directory browsing for file and directory selection (press square over ZIP/RAR File: or Extract To

.
- __SCE__ to KXploit renamer (mainly for iRShell users).
- Auto detects whether launched from iRShell or as standalone.
