Hellcat has updated his Pandora Installer for 3.xx Kernels.

Changes:

Revision 2: Now you can now also perform the actions on the memorystick, you so far needed to use “mspformat” and “msint” on the PC for! That is repartitioning and formatting the memstick to reserve some space for the MS IPL and then install the IPL (MSIPL.BIN) into that reserved area. The “Pandora Installer for 3.xx” holds options to perfom those tasks with a simple button press! No more hazzeling around with the command prompt tools.

….and yes, can use this to install ANY msipl.bin, not only the original one (Boosters multiboot, for example)

Please follow the instructions CAREFULLY if you use this application!
