Is there any way to ID what chip a slim PS2 has in it without opening it? There are no outward signs other than a small sticker over one of the screws that says E2G. The seller didn't know anything about it other than it came pre modded from the Phillipines. It does have a Euro power brick.
It seems to work ok, I'm just curious if there may be more to it than booting imports/backups.
