Hi Community. I hope you can help me because I am not able to find a solution for my problem. I bought a R4 SDHC Dual Core Flashcard and tried different roms on it. I was suprised that Pokemon Black worked so well, without EXP or Freezing probs. But now i found something: I got the C-Gear and tried the Wifi Connection on my 3DS. In the C-Gear i see 3 bars when i look at the signal strength. But when I try to connect to a Wifi Battle or to the GTS, the Game shows me an error (51099). I hope you can help me because i would like to try the battle system or the GTS. Greetings Kev EDIT: I think i found my solution, r4 doesn´t support dsi features, and wpa is one. Thread can be closed.
