According to the driver it's the CPU board that has the TGP that differs.
It's hard to say whether it will have a different TGP. Those chips are off the shelf chips with a mask option, so if they ordered a new lot then getting a new program included wouldn't be a problem. Obviously they'd need to do development work to do that, it depends on how invested sega were in the project up front. It could have just been a "use whatever boards we have lying around" type project or it could have been more important, you can't really tell.
