Ok. I did a similar thread over in the GBA arena and you guys were great on getting me hooked up. Now I can create my own backups and don't have to rely on outside sources for those items. Now I would like to do the same for my Nintendo DS game carts as well. I have the following hardware to work with right now. R4DS Slot-1 cart M3 Perfect Lite Slot-2 cart Action Replay DS cart (usable as a NoPass by holding down Select during boot) I have the following software to use at this time. Tricks on using this software or pointers to other software that may work for my task are appreciated. M3/G6 Rom Dumper WRT Dumper Progress: M3/G6 Rom Dumper R4DS + M3 Perfect Lite -- Forget it. It sits for several hours -- asks to reinsert the cart and won't continue. It won't even accept the R4DS to continue. Filesystem gets corrupted because it didn't finish building the file. Action Replay DS + M3 Perfect Lite -- Well it appeared to work. Went surprisingly well. I had inserted in the cart to be read (Children of Mana in this case) and it continued. Then it asked for the original cart. It wouldn't allow me to simply reinsert the same cart. I actually had to reinsert the Action Replay DS unit and then it would finish. I got a file from it and it is the first time the file system didn't get messed up as a result of my attempts. WRT Dumper R4DS + M3 Perfect Lite -- Only get GBA dump option -- can't even dump those complaining of no suitable storage M3 Perfect Lite only -- Only get GBA dump option (obviously) -- same result as when I had an R4DS inserted Action Replay DS + M3 Perfect Lite -- Get menu for NDS or GBA dump but selecting NDS option comes back showing the id for the Action Replay DS and complains of no suitable storage for the dump. So... ummm... I could use a little help here. If there is different hardware that I should get for this task then I am open to suggestions. One thing to note here..... FlashMe is not really an option at all. The last thing I want to do is risk potentially bricking my ds and voiding my warranty.
