There are both boards with Japanese and US Bios in them...just like the MVS.
However unlike the MVS most games are territorially locked out from working on both boards. Going for the Japanese board is indeed your best bet, but keep in mind that the games will be in Japanese.
As far as a game list is concerned look at <a href="http://www.system16.com" target="_blank">www.system16.com</a> in the Sega Titan ST-V section. That list is farly accurate, but I think Dynamite Baseball, NBA Action, and Virtual Mahjong are nonexistant (even though they list em)
As far as what games weren't ported over to Saturn...well beyond the obscure quiz and mahjong games (and they are probably there too), I can't think of any. The STV and the Saturn are afterall basically the same hardware.
I think I need to write an FAQ or something on this.
