My PS3 PARAM.SFO Editor is now in version 2.0... The major addition is that it now allows to add new fields to a PARAM.SFO, which is nice for the PARAM.SFO that don't have some fields, like the ATTRIBUTE field (which allows Remote Play from the PC or PSP).
Awesome, but i guess owner ID is not available. That's the real problem: how to make a param.sfo compatible with our console without an other param.sfo used with our game.
For example, i was needing the white knight chronicles 1 savegame for import an uber char from an other guy, and use it with my WKC2 new game. Failed, because i cannot put me as owner. I don't have WKC1 , so i don't have a "base". Damn.
