Au contraire, mon frere (yeah its not spelled right)
The Turbo+CD is NOT the same as a TurbDuo (or DuoR/DuoRX...whatever)
the Turbo+CD will NOT allow you to play SuperCD's, just Turbo CD's
64K games vs 256? Its been awhile, but i think those are the specs, and you will get a HELL of a lot more fun from your Turbo if you feed it Super CD's
You can get a System 3.0 card or an Arcade Card PRO (make sure its a PRO) to get the full benefits of the Turbo Library. I'm fairly certain Arcade Cards are plentiful on the market, but they need a convertor which are not.
System 3.0 cards WERE released in the US, no converter needed, you just can't play Arcade card CD's (which are all Japanese, but ALL forms of Turbo CD's play on any system with the right operating system card, no region lockouts)
