So I've recently installed Arm9Hax on my O3DS and I'm currently running AuReiNAND with 10.7.0-32E firmware, but I have one problem - I can't get my DS games to work. I've first noticed the problem when I tried to run Pokemon White 2 from my old, original R4 (using Apache Thunder's R4 TWL Launcher), immediately after loading my savegame the game crashed with "Communication error. Please turn off the power." message. Same thing happened while trying to load other Pokemon games with that R4, though they all work perfectly fine with the same R4 on my DS Lite. So I thought that maybe there is something wrong with the launcher itself, or patched TWL_FIRM file that I've installed, but then I found out that even after restoring the original, unpatched TWL_FIRM, I can't load my Pokemon White 2 savefile even on from a retail cartridge! I haven't tried any DS game on my 3DS for a while, so I'm not sure exactly might be causing it, but here are the symptoms:
- After going to Settings->Internet Settings->Nintendo DS Connections->Nintendo Wi-Fi Connection Settings->*empty connection profile*->Search for an Access Point, it freezes up, doesn't react to any button except Home. If I try to set up the connection manually and then test it, I get "Error Code:6 Nintendo WFC Configuration Transfer" error.
- After starting up any Pokemon Platinum/Heart Gold, it crashes on the menu screen with "Communication error" (before I even press "Continue game"). Tested with original R4 for DS and Apache Thunder's R4 TWL Launcher, aswell as newer, R4-SDHC, which supports 10.7 3DS out of the box with the latest kernel, and was loading them without a problem last time I used it.
- Trying to load the Pokemon White 2 from retail cartridge results in a communications error if I select "Yes" on "Launch C-Gear communications?" prompt, if I select "No", the game loads normally, but I have no access to internet features of the game. Exact same thing happens when trying to load Pokemon Black/White/Black 2/White 2 from either of my R4 flashcarts. They all work fine on my DS Lite though.
- Restoring unpatched TWL_FIRM has no effect, so I suspect it isn't related to this problem.
- Other DS games, that don't use Nintendo WFC (like Trackmania DS or Super Mario World), work without a problem.
