I’ve finally gotten around to finishing my SelfTool for manipulating Self and Sprx files. Self files are like exe files for the PS3 and Sprx files are like dll files for the PS3.

Among other things, SelfTool can be used to print out information stored in the file in a readable format to make studying them easier.

NOTE: This DOES NOT enable booting of copied games in any way. It also does not support decrypting or encrypting of self/sprx files. It is really only useful for those who are interested in looking a bit deeper at self/sprx files.
