Yes, Xbox360 gets the exact PS3 - Players, -Coaches, and -Team data imported.
RPCS3 is essentially the same file as offline PS3 file, except it's Bruteforce "Decrypted" so it can work on RPCS3.
Update2: I just re-checked the last 9-30-20 PS3 Offline file, and The teams are the old teams names, but Coaches are ok. They are NOT the Coaches for Idaho, NMSU, Uconn, Umass. So, I don't think Vikesfan has to correct anything...I also checked back to last Sept 26 update, and Coaches data had the old Team name Idaho, but coaches were correctly showing for App State (Shawn Clark).
