This may be old news. I recall that even though the game
Take The 'A' Train III / A. III A列車で行こうIII
is listed as a Super CD Rom, It will not play in a US system with a super system card. I was even told this by the seller BITD so I got it for next to nothing since I couldn't play it.
I haven't tried it in my TGCD with a kisado and the PCE super system or arcade card.
Were there other games that had this problem?
What do you mean ? Do you know that some CD games won't work well depending of the system region ?
Which ones? I've heard of system card incompatibilities, of course, but I don't recall hearing of any region troubles.
