CPS II/III Region Settings?

I'm still relatively new to the CPS II/III but I was looking on coinopexpress earlier today and noticed some pretty cool games. However, it seems that the majority of them were in Japanese; is there any way to play these games in English (Such as how MVS games can be played in different regions via UniBios)? Basically, if I have a SuperGun setup with a CPS II/III harness and UniBios installed, is there any possible way to play the games in a different language?

There is no way to do a UniBios-like chip for CPS2, as the game board itself determines the language. But, for a small price you can have Razoola convert your board to a "pheonix edition", which gets rid of the suicide battery (and can convert it to a different region board in the process.) That's what I did with my Super Puzzle Fighter 2.

So, every CPS II/III game can be converted to English? Roughly how much would it cost to have a board modified by Razoola?

CPS3 games' regions are determined by the security cart, not the board. That's all I can add..
