FINALLY, I GOT IT TO WORK. The card reader was bad and it works in my friends laptop (he has built in slots for them). So I have been able to run DS games using the settings from here: http://www.m3wiki.com/index.php/M3 So far I only tried to run Yggdra Union (GBA) and it won't run. I wrote it three times (always with save option), but the M3 guide here said to use "Software + Hardware" for the patch. The only three options I have are (gamemanager and firmware at v32) "Soft Patch" "Hardware 1" "Hardware 2" I tried to run the game using all of these options separately. I turned on my DS, pressed start to run in GBA mode, and tried to run the game. Every time the game would get a screen that says "loading 0000kb" and nothing more would happen after that. Maybe its a bad rom?! It seems there isn't much for GBA settings on M3 Wiki, so I assume they are all the same. What is wrong here? Thanks, all help is appreciated I'M SO HAPPY IT IS FINALLY WORKING!
