Description:
v0.8.5 Fanjita's Eboot loader for the v2.0 PSP Firmware . from the included readme.txt:

This program builds on the work done by Saotome to load homebrew EBOOT.PBPs into PSPs with v2.0 firmware, using the TIFF exploit. It will not work on any other firmware version - including v2.01.

It currently cannot run all known homebrew, but it uses a number of tricks to get substantially further than ever before. Known limitations are:

• Can't run kernel-mode applications.
• That means anything that uses wi-fi or USB access, or emulates ISOs/UMDs.
• Some minor system calls are still unsupported.

It's also still very much in development, so the user interface isn't very nice to look at, and a lot of the output is cryptic.
