It's official - The X360 and PS3 compendiums are completely incompatable.
To be precise, all the numbers past the original 16 for base costumes, and 15 for Extend costumes and any accessory past 24 is now officially invalid if you try to cross port them.
I've just fully completed all the sidestories, and now have all their gear, and noticed something.
They inserted the costume set that's tied to Nana Iro Button PRIOR to any of the DLC, and since it doesn't actually exist in the X360 version, well...
This has the unfortunate effect of kicking every single number post 16/24 by one or two, depending what it is (I say that, because it seems that the hamster's done a number as well as oddly enough the horns which let me swipe it for the grand price of Kami Summer only, and Miku's costume makes the Extends go +2 instead.)
In short? There MUST be two seperate compendiums. No ifs, no buts. Codifying MUST NOW SPECIFY the console type (X360 or PS3) due to the code, EVEN IF it can be filled on either due to this (ie any of the shared songs). You can end up with completely different items if you specify a code high enough.
I'll be in the priocess of updating all the code (and steeling myself for a lot of repetitious screencaping) when I purchase the first PS3 DLC set.
I would also strongly advise that all requests that can be made with the PS3 version be made with it, only because well, between the incremental improvements (Subtitle removal and the choice of camera chase), and a video I'm going to upload very shortly, there's limited reasons why you'd want to. (Namely, you might want the DLC that is on the X360 version)
Currently, you gain all costumes and effects from Kyun Vampire Girl to I Want that aren't present in the PS3 version.
Personally I won't be actively able to update the X360 compendium. The PS3's eating the budget more than even I anticipated. If you REALLY want something, or want the compendium to reflect changes, you can either throw the points my way, or you can talk with me so we can add the missing images and the like. (Although it's unlikely I'll be accepting code suggestions unless you can prove (via a screenshot of your gear collection) where they'll sit.)
