When I first entered the PSP scene, I had limited knowledge of file names and terms used with forums. Though, now that I have a bit more knowledge, I think I could create a PSP Jargon Dictionary. Here is a list of words and terms that you may come across in forums or websites: Types of PSPs PSP-1000 - FAT / Original PSP OR PSP FAT PSP-2000 - Slim PSP OR PSP Slim PSP-3000 - Brite PSP OR PSP Brite PSP-N1000 - PSP Go PSP regions PSP-x000 - Japan PSP-x001 - US / North America PSP-x002 - Australia / New Zealand PSP-x003 - UK PSP-x004 - Europe PSP-x005 - Korea PSP-x006 - Hong Kong / Singapore PSP-x007 - Taiwan PSP-x008 - CIS PSP-x009 - China PSP-x010 - Central / South America x = 1,2,3,N1 File Formats EBOOT.PBP - A File format that is usable by the PSP.
