I can not figure out what version I have. Its a slim PS2 and only about a year or so old but, there is no sticker on the bottom my son pulled it off. Is there any other way to find out what version I have. From what I have seen the only way to tell is with the sticker.
when u boot the ps2 with no cd or mem card in. go thru all the options menus. i kno somewhere in there u press triangle and it will show a list of drivers, one should be your scph number....
not with any real acuracy no. http://www.mod-chip.com/en/ps2version.htm there is other information on that sheet, but you would have to find a screen that tells you things like which BIOS it is running.
