All nopass devices are the same and are a copy of the original Datel media launcher card..
As azndragonguy115 said Datel was one of the last no pass devices to the market and they had the worse model once they did release. Their first model had no sleep mode and had problems working with some flashcarts. Now they have fixed the issue and the MMP is just like any other no pass.

No. Max Media Launcher was actually the first NoPass device on the market, and the cheapest (if bought on the "western" side of the World, of course).
It was then followed by SuperKey and, few days later, by PassCard3. Maybe they all copied Datel, maybe not. By the way, they were produced by the same fab, so they were exactly the same thing, but with a different label.
The "problem working with some flashcarts", was a cancer of every Device, still going on (DS-X vs M3).
There wasn't "sleep mode", just because they didn't short PIN 1 & 8 (or it was 9?) on the cartdridge, but was pretty simple to make it by yourself, even without opening the card.
PassCard3 & SuperKey did not have this problem because M3/G6 Team already knew that (it was a feature of the latest PassCard2, that not anybody knows).
Sorry for my ugly English...
Bye.
