I found a MAME Slow Poke edition that seems to support all the sh3 games.
Is that what you mean by a pre built version. Can someone explain to me what these editions are (if there are multiple) and are there any advantages to adding the drivers to the most current version of MAME over the Slow Poke edition.
I found the sh3 driver text but it all seemed very complicated (I'm still learning).
Cave asked MAMEDev to remove the games from MAME (because they were still selling the hardware) and MAMEDev complied with the request.
It's not in the official MAME build anymore, nor is it in any of the previous builds available for download on MAMEDev.org
The code to run them was in one of the interem "u" updates. The "u" updates require people to compile MAME from source code themselves.
Those who downloaded the interem source code and kept it can add it to newer MAME builds before compiling.
I had it, but deleted it before I knew anything had been removed from the following bulid.
Not that big of a deal. I have three other variations of MAME from around the same time that can run them.
I just treat it like a different emulator.
