The system cards

From <xxxxxx@aol.com>

Hello everybody. Yesterday I got my CD unit, and I played Ys Book 1 and 2 
all night! I love that game. Anyways, How can you tell apart the System 
cards? Mine just says TG-CD system card. But on the loading screen, it says 
Version 2.0 on the lower left of the TG-CD logo. Is this card a 2.0 card? and 
now what the hell is the difference between the 1.0 and 2.0 cards ( they can 
both play regular cd and Super CDs right?) 
   
     And now an unrelated question, in Ys book II, i'm in burntown. There's a 
field of Gas blocking my path. What do I need to pass it alive?

   Thanks again everyone
