Namco System 357 emulation

No. Unless the games boot and behave exactly like they do on a PS3. But very probably nope.

This was an update suggestion. I think that Dolphin emulated Triforce at one point RPCS3 could do the same thing with PS3 based hardware.
I just wanted to see if I could play Deadstorm Pirates on PC. Maybe in a later update.
Here is some info on it:

I am sure it can be emulated with rpcs3 code. Just somebody need to reverse engineer whole system and adapt rpcs3 codebase to namco initialization procedures. Its not easy task to deal with all arcade encryption stuff
