Hi. I was wondering if there are any important technical differences between the Messiah2 versions, other than working with different versions of PS2. The chips I'm wondering about are: Messiah2 Pro v.1.30, Messiah2 Pro v.1.22a, and Messiah2 USA v.1.07. I'm wondering if there have been any "magic like" issues in the earlier versions of the chips. The reason I ask, is there is a significant price difference between the M2pro 1.30, and the M2 1.07. Any information is greatly appreciated. Thanks.
