OK, so I own a cart of Chinatown Wars and I have the game backed up on my R4. My brother recently got a new DSlite from somewhere and so I let him use my cart and I used my R4. So we try multiplayer and... game disconnects us rather quickly on every mode except LC Survivor, which it lets us go for 2 seconds, or 2 minutes. I dont know how that works out. This sounds like a recipie for a patched cart, but A.) The ROM will not run on my (original) R4 without using YSmenu and B.) Wifi works perfectly for me. I even tried some of the flash games on the website and received my Patriot. So, what's the problem here? And no, my rom is not patched.
Oh, a few more things to add. Trading and chatting work perfectly between my brother and I.
