Did you make sure they were named properly? That fixed it for me.
Yeah, I found the correct one after a 2nd pass on the 15 bios files. Now can someone enligthen me as to why this happened? I had the old bios FFVII.bin with the FFVII.cue and all of a sudden it didn't work.
Also, I lost my save point as I got an error of "save didn't match with blah, blah". Luckily I just started with it or I would have a smashed N9.
By design the 3rd party controller has to comunicate using the same protocol as an official one or the ps3 wouldn't know what to do with it -
I'd be very surprised if it didn't work.
