To quote from xorloser's Web site linked above:
This is a PS3 loader for IDA, it lets you open PS3 elf/self/prx/sprx files in IDA. I highly recommend you use this with the PPC-Altivec plug-in also available on this site.

THIS DOES NOT DECRYPT ANY FILES !!!! That means that for now this loader will ONLY work on unencrypted files. There are a few such files "in the wild" that have been found on Sony update servers and such.
As well as loading the supported PS3 filetypes in both 32bit and 64bit vesions of IDA this also resolves and sets up all imports, exports and syscalls. It also only supports PS3 PPU files as the PS3 SPU CPU is not supported by IDA at this time... More »
Today xorloser let us know he has updated his tool (with PS3 support!) which can edit ARK/HDR files found in games including Guitar Hero 1, Guitar Hero 2, Guitar Hero 80s, Rockband, and Karaoke Revolution... Guitar Hero 3 uses a different format, so it is currently not supported.
Both the tool and source code will work with those titles for any system including PS3, PS2, X-Box 360, and X-Box. Note: In order to use this via PS3, you must have a Debug PS3 for the time being as there is no public way to run PS3 back-ups via retail consoles.

You can now replace a short song with a longer song (ie replace a small file with a bigger file). Previously, no tools existed which allowed this kind of editing, and you could only make custom songs by replacing the existing songs with new songs that are the same size or smaller.
