So I was trying to get the SCD version of Tengai Makyō to work with Ootake (the way I've been playing PCE games past couple months), and for whatever reason I'd get the "you need the SCD 3.0 card to play this game" error screen in the beginning. I thought, what the hell is going on, I DO have the 3.0 system card image loaded on there! Then I realized that I had the U.S. version of the system card loaded, and when I tried the PCE version, voila! It loaded fine.
So... I wonder if this happens on real hardware. Have any of you tried the game (specifically the SCD re-release version of Ziria), with the US system card? Actually that's a two part question -- 1) Does this game boot up on a separate, US version of System 3.0 card? 2) Does this game boot up on a stand-alone TurboDuo?
I haven't heard of any games actually needing a region-specific system card before (other than GameExpress cards, which is obviously only one region), though I thought I recall reading somewhere on here that a few demos didn't work with US cards either...
