I've been seeking to fix my problems with wifi homebrew for the last 2 days or so, and have fortunately found an awesome fix! It is a patcher which fixes non-working wifi homebrew. i cannot vouch for its complete safety or compatibility but it has worked great for the 3 apps i have thrown at it just now (DSliveweather, IRCDS offhand, will post more test results soon) The patcher is made by nin187 and based of Rudolf's findings. Rudolf's blog here: (only in Japanese) http://blog.so-net.ne.jp/Rudolph/ Where i originally discovered it, and a translation: http://www.1emulation.com/forums/index.php...ndpost&p=228195 The patcher is linked in the comments of Rudolph's blog. Here is a direct link (long 0_0) for those who want it: http://ftp7.ohpy.com/opftp/index.php?contr...0HDbTgkp65PpA== i don't know how complete it is since nin187 makes a post below which is uninterpretable via auto translation which has a new link (Albeit broken). Since i don't know how many others have tried it and i have not done extensive testing try at your own risk! Also don't expect this to fix bad settings with routers or DS wifi firmware settings, this only fix the homebrew that wont work even if those settings are right (even though they might work with other people). of course make sure those are right first. Edit: heres an ongoing list of my homebrew that I have tested from my ez4. none of these worked prior to my patching (except IRCDS which was irregular) DSLiveWeather: works IRCDS: works Wifi Lib Test: works Wifi Ez4 Loader: works (havent figured out how to use yet) DSamp: works DiagnoSe: works SylphAmp: works Beup Live fixed version: works Unsure whether it works... (dunno whether anyone plays these games wifi anymore..?) Wifi Voice Chat Client Tetattds (i can't tell if i'm playing AI or another person) ExplosiveGas EDIT Oh, i just realised something POTENTIALLY DANGEROUS reading the translation; it's hard for me to understand the context of this and i have no clue as to whether the patcher ignores this patch or etc 0_0 Please read the translation link i provided to make your own judgements.
