I have some PS2 Tools with the Sony repair warranty stickers. You may have seen them, the warranty sticker has hiragana on it. The Tool has an "R" added to the serial number. The case has new marking and stickers, some over old asset tags. They have "revised firmware" stickers on the case. The motherboard appears to be an updated one and not the original 10k motherboard. Anyone have a tool with a revised serial number and modified internals?
