Hi there. Just wondering is the EMS memory adaptor compatible with all versions of ps2? I have a version 5 scph 30001R with Magic2. And is it any good? How's the transfer rate? Cause i notice there are now 2 different kinds of the EMS memory adaptors. One is the original printer port version and the new one is the usb version. I noticed the usb version is MUCH more than the version that just connects to the pc printer port. Can anybody comment on the difference in performance for these 2 version? Thank you
