Similar to LS Cover Manager and other Open Backup Managers based on Jurai2 Mods, Open Manager v2.1D is now available along with an Open Copy Install v1.0 application (with source code) for PS3 JailBreak users from wuepe at Elotrolado.net.
To quote, roughly translated courtesy of maverick83: With the release of v2.1D, there is an introduction of a new tool, which is Open Copy Install.
The tool is an utility that allows checking games installed on internal/external drive, deleting, copying from one drive to another drive and patching installations on internal drive. It is very useful if you want to do it on the fly for your JailBroken PS3.
Open Manager v2.1D Changes:
• Added Menu Language English, now detects the region if it is Spanish, Spanish shows BG3.png, if you build a BGX where x is the region of the menu display language of their region, but in this 3 and 1 English, if not is the default file will English.
• Added automatic patching to add the improvements of the last payloads (OM Opening the patches automatically, do not press anything special)
Now both PSGroove v1, Hermes v1, v2 and PL3 Kakaroto add these features.
• Added able to play games that require v3.42 modified before the moor.
• Added more patches to prevent update errors. (To be confirmed if left unpatched memory PL)
