I have a DSTWO (1.17) both a DS Lite and 3DS (4.3.0-10) from the US and I have no problems at all with either system. I also just purchased a Japanese DSi LL (1.4.4J) and I cannot seem to get the DSTWO working. I get the "Alex" logo but when I launch the game I get this error message. I have tried doing the firmware/EOS update from http://jp.supercard.sc with no luck. Any ideas?
