I just bought a SCPH-50010/N date code 3C and I've been told this is a version 10 PS2. I have a few buddies that use the older messiah on their version 7's and they're happy with the results so I'd also like to use messiah. All of the product details I've read on the messiah 2 say it can be used on version 10, but they don't have the instructions for it... or version 9 for that matter. Can somene tell me if this chip is a good choice for my version and where to get instructions for my version PS2. Also, could someone confirm that 50010/N is a version 10 and is compatible with the messiah 2. Thanks.
