I haven't tested mine with DSLinux, but it works with SNEemulDS and Moonshell, so I see no reason DSLinux would not be supported. It is 32MB (compared to 16MB for the EZ43in1), however, I've heard one report (unverified) that some homebrew app detected it as 28MB or something like that. The actual ram chip inside it is definitely 32MB though, so I don't really understand that report.

Anyway, try this site:

They're in Ontario, and charge US$14 without shipping.

 

Ugh, triplepost!

My internet connection is lousy, and I didn't think my reply went through. :/

 

The Ewin is also cheaper, looks better (doesn't stick out), and has faster load times. I'd recommend it over the 3-in-1 to anyone who doesn't want to dump roms (or has another card to dump roms with).

Part of that is selfish though. I hope more people will buy one so there will be more interest in making a third-party loader for it.

 

yes, got mine from psxboy too.

I like it better then the 3-in-1 card, faster loading times and exactly the same size as the dustcover.

Also some good hardware inside. Samsung memory and same chip as used in the m3 and g6 adapters.

too bad there's no rumble, but who uses that anyway?

 

I'm probably late on this but I got mine from http://www.sky2k.com/

They're located in Canada and give good service.

Edit: Scratch that, sky2k is weird. They didn't send my EEP in the box and it came with a different decal. Plus, it came from Hong Kong which leads me to beleive that they are fibbing about being located in Canada.
