So if you are using PSUpedia, here are some notes to help you know what is and isn't JP content.
Rows highlighted with a green background represent items which are exclusive to the Xbox 360 servers. This includes weapons which were renamed and released with existing models as replacements for weapons introduced on the Japanese PC servers by AOTI update 2nd and 3rd. Also included are weapons which are bound by the GUARDIANS Cash system which were released on the Xbox 360 servers by an alternate method.
Rows highlighted with a light green background represent items which currently are available only on the Japanese PC servers, but likely will be released on the Xbox 360 servers with their original names and models in tact. Alternate methods of release will be required for GUARDIANS Cash weapons (and those released through alternate features exclusive to the PC servers), but all others should retain their drop or exchange sources.
Rows highlighted with a red background represent items which have not been released on either the Japanese PC or Xbox 360 servers.
Please keep in mind that some of the weapons that you list may not be able to be added for now! If you have any questions let me know!
