Can I still get Skate 3 DLC on PS3?

So I'm little late on the whole console thing, since I got a PS3 almost a year after "The Last of Us" came out, because I felt I've missed out on a lot of great PS3 exclusives and PS3 prices rocketed down after the new generation came out. That's why I'm asking this question now. Looking through the trophy list on Skate 3 I noticed that there are a lot of trophies, which are part of the DLC packs that they've released years ago. I'm aware that they no longer support the "skate.Create" service so I can't get all the trophies, but I couldn't find the DLC for the game on the PS Store. So what I'm asking is if I can get the DLC, through some in-game option I haven't noticed, is the game completely unsupported now (including online content, DLC downloads, etc.) or are there some region restrictions for DLC content (I'm from Bulgaria, using a Bulgarian PSN Profile)? I do get the online features getting cut out of a 5-year old game but just deleting DLC seems weird. So is there a way I could get it or is it just gone?
