I pre-purchased BBCS:EX LE for PS3, and also for Vita though I didn't have a Vita yet. After playing BBCS:EX for a several weeks on PS3, I've finally got myself a Vita. Truth be told it's my only Vita game so far, and I mostly bought the system for Blazblue.
Before purchasing, I came across many reviews and descriptions of the Vita version having "cross-play" with the PS3. Amazon.com description reads as:
"PS Vita players enjoy cross-compatibility with PS3 game version and optional touch controls if they so choose"
I was really looking forward to being able to share saved games and trophies between the two.
After finally getting my hands on both versions of the game, I have not been able to find any way of transferring any type of data or play. This is going on several hours of frustration at this point, including personal trial & error and searching online. If anyone reading this can give me any info or advice, I would really appreciate it.
