Stone Age Gamer Turbografx EverDrive Question

[segamer]

I have a question in regards to your EverDrives for the Turbografx-16, can they be used as a Super System Card or Arcade Card? If not, can they be updated to do so?

Super System = yes (that's CD card right? I get TG-16 stuff confused sometimes)
Arcade = no

I believe the Arcade card required extra memory or something which is not supported.

As far as I know, the Super System Cards and Arcade Cards are just ram expansions. Yes, the CD card. I've been interested in this but couldn't find info if it acted as a Super System Card 3.0 or higher.

Maybe I am wrong about the Super System card then. Its not really clear when I Google it either. I even asked the developer and he said "I honestly don't know."

So, let me explain. A Super System Card allows a regular Turbografx-CD to play TurboDuo games. It's just a ram and bio update. I should mention that the Turbografx CD and Duo games are region free. The Arcade Card was the last iteration of the Super System Card, which again added more Ram and another updated bios. Domestic Super System Cards are rare as they could only be ordered by mail. Often, in order to use the Japanese cards on american systems, one has to have their system modded or use a very expensive TG-16 to PC-Engine Converters. If your everdrives simply had the bio and allowed the system access to the ram, it would be cheaper then all the alternatives.

Can I ask a related question? Maybe this has already been asked..

Those orange cases you use, are they made special for you or can I buy them somewhere?
