Nothing more then is in that thread above, there we're absolutely no roms or warez on the site cause it was a wiki, it was just information, information that anyone could find on google in 2 minutes. personally the restriction of information is something I don't agree in, I can see linking to downloads, but not just information on how to mod your PSP or what games will run on it.
All in all though, I would suggest just using google to find out how to run SNES games on a PSP or contact someone who knows how to do it rather then anyone posting information here in this thread.
