I just received the DS-Linker from Kick Trading and I have to say it's pretty good. This is the first time I bought something like this for the DS and I recommend it. Right out of the box it looked alright, I thought I was going to get a usb cord along with it but I didn't which was ok since I have like 3 of them lying around. I've heard of the DS-Linked having horribly slow uploading time, but I uploaded almos 850MB in less than 32 Minutes. One person claimed it took him 30 minutes to upload 3 games or something, which was weird. The loader had a little problem where I had to jiggle the usb male part into it because the inside of the socket was bent upwards a little, but not really a problem. The Menu is not too pretty, with 3D cubes spinning around with pictures of the game, It's alright, but annoying. I haven't tried any homebrew apps except DS organize, which didn't work. It was on the third page and i tried to view it but it froze so I deleted it. Games work great, as if I were playing the real thing. One time though, the game was loading to another screen and it froze, i restarted and it didnt recognize the cartrage, I took it out and put it in again and it worked. A lot of people don't trust the DS Linker but so far, I think it's pretty good. I have yet to try multiplayer features, but overall, if all you want to do is play games on this, then it's great.
