I have an XPORT Datel X-Link, and I have both 10k and 30k Japanese consoles, as well as a U.S. console, and I've been trying to back-hack jap-us versions of onimusha 3 saves (I have both Jap and US versions of those) with no sucess, yet. But I sill might be able to help you out, if you have an xport cable, we can email saves and such, just because I have the Japanese machines and the tools. I you do email me both versions of the save in xps sport format, and I'll try hacking them up.
A toxic agent on a dangerous mission so secret, even I don't know what it is, because if I did, I would have to kill myself. I don't even know who's side I am on.
