I have two DSs with supercard DSTwo. I tried both patched and non-patched versions of the games and still gets the same ERROR results. Here's what I did:
-Added both players friends code.
-Go into the Wi-Fi Room (middle NPC) in the POKeMON center.
-Connected Successfully on both Black and White on two DSi
-On Screen: [My Name Standing by... ]
-Go forward to the COMPUTER and press A to access the options on the first DSi and selected Live Caster or Battle.
-Seeking participants...
-Second DSi screen, PLAYER 1 is jumping up and down. I then press A to PLAYER 1.
-Text says: PLAYER 1 wants to chat using the Live Caster. [Apply / Cancel ]
-After selecting the APPLY option, text says: Communicating with PLAYER 1... Thennnnn it's either:
**** First DSi, text says PLAYER 2 joined you! then says PLAYER1 Failed to respond.
or
**** 5 minutes later... COMMUNICATION ERROR, blue screen on the second DSi
Has anyone successfully used LIVE CASTER or Wi-Fi mode using a FLASHCARD?
