Hello there, my name is Mike. I would first like to express my appreciation to those involved in maintaining such a useful resousre like the afterdawn forums. Of course I feel like a jerk for contributing nothing, but I don't know who else to ask. Here is the issue: bought a ds lite in japan and some games. bought an m3 and passkey2 combo, used it with mario kart (J) as the passkey lead card. Everything is dandy. Today I mailed mario kart (J) to my GF, and I decided to load the ds with a different cart. I chose Super Mario DS (J) because my other carts dont seem to be compatible (mario DS is listed as compatible however) I went through the process of re-setting the lead card to the correct game.. but now when my NDS boots from the initial info screen... it just goes to blank white. I even upgrade my passkey firware.. I cant seem to get the passkey to work with Tetris (J) or NewSMB (U).. i think because they are too new. I would test the unit to see if it is broken by using it with mario kart again... but it is allready in the mail. I serarched and I was unable to find an answer to my qquestion.. sorry if it is a newb question. I appreciate any insight in to this issue. Thanks, Mike
