Can't get it to work on what? What settings are you using? Where did you get it? You need to post more info than "I can't get it to work" Works on Trim and Safe Mode on the M3.
I am using a g6lite, U-disk v4.4, Supercard, Trim Rom, Dofat(default), soft reset. I also can't get Advanced Wars to work under the same config. Also udish won't even write the rom unless it's unzipped, if zipped it does nothing. Thanx for the quick reply
In the U-Disk Manager use the Safe Mode to write the ROM, make sure it's unzipped first. As for Advanced Wars, try using Normal Load and No Soft-Reset.
