Which is older the Bor engine or the SORR engine?

They are both kinda similar?

I was wondering because I read that post last week about the guy who stole stuff from the BOR/OBOR engine and wanted to say he made it himself.

But I really doubt the SORR team would do that.

Anybody have any ideas? Please help?

Well, of course the BOR and SORR engines are somewhat similar, as both were created for Streets of Rage style gameplay. But as far as I know the Bombergames team created their engine all by themselves in some sort of game programming environment called Fenix. Also, I believe they were already working on their engine before Beats of Rage was released.
