Hello,
Thanks for replying. It's a v4 with a date code of 1D.
I saw only 8 screws on the bottom of the console and no screws on the expansion bay in the back of the console.
I'll email you to get a quote on the price of the Messian chip and also if you know of any installers who can add this chip to my PS2 chip here in Southern California, USA.
Thanks,
RKRA
