EZ4 Lite & WIFI - Solved! Let me start with I was very pleased with the ez4l untill i discovered its dark secret. It seems as though this cart lacks the ability to play on nintendo wifi, for pretty much every game. (unless some one can prove to me otherwise) here is what I have tested. HARDWARE I have a japanese ds lite (white), flashed with flashme v7, I have a M3 mini sd adapter w/2 gig mini sd (sandisk), I also have the EZflash 4 lite w/ 1 gig micro sd (sandisk) All devices are loaded with the latest firmware, as of the writing of this post. ezloader 1.67 ezclient 07/10 (beta 3) ROMS TESTED 0168 - Mario Kart DS (USA)(SCZ)(D47555BE) 0366 - Tetris DS (USA)(WRG)(377536D4) 0367 - Metroid Prime Hunters (USA)(WRG)(7FE4554A) All loaded to the cart with the latest EZ4 client. All the roms work well as far as single player, playability goes. It turns ugly when you try to play online. Every rom will error out with ERROR: 20109, which I have found to mean it thinks your online name is blank. (which its not, this was checked.) And in the case of Tetris, once it gives you this error and you click next the rom will freeze. All of the above roms were tested on the same unit, with the M3 adapter and work flawlessly, single and online. I even went as far as to wipe out all of the NWC settings and start anew... When I did this i discovered another interesting tidbit. When you connect to NWC your DS is assigned a Connection ID its 4 sets of 4 numbers. 0000-0000-0000-0000 when you clear this out, and try to re-establish connection to NWC with the EZ4 lite, you will not be able to make a connection at all. I had to put my M3 back in, in order for it to reassign me a connection ID. (of cource all my friend codes are all now changed.. damnit...) Once I was assigned a new connection ID, I could successfully make a test connection to my wireless device, however allas I still got the same Error: 20109 when connecting with any game. CONCLUSION Knowing what I know now... I would not have purchased the EZ4 lite, appeartly no one is testing online play with this cart in any of the reviews.. Now, Don't get me wrong. I don't have 40 f these things laying around to test them all, so for those who have one, please try and test WFC and see if you can play any of the 6 or so WFC roms out. See if you get the same issue.. If you do get it to work, please post what version of the client software you are using, and what loader version. SOLUTION Turns out that the latest beta 3 of the client software is to blame. I was able to use the 05/24/06 version and repatch the wifi games and they all work now. Tetris will still lock up on you after you complete wifi or if you do not connect on the first try. They still need to fix this. Other than that things look good.
