Post here if the 1.63 firmware broke your supercard. Let's try to get as much info from people and hopefully someone can come up with a fix for this. I figured i'd start this thread because myself, as well as others from other forums are having problems with the new 1.63 firmware. Here's what I did: I put the upgrade.scu file into the root of my minisd and turned on the ds. It comes up saying: Old ver 1.62 Now ver 1.63 I press start to upgrade. It gets to 32% and says: write flash error. Turn off GBA, upgrade again. No matter how many times I try this, I get the same thing. Now my supercard does nothing. The bottom screen shows the supercard logo and the top screen is white. I've tried different miniSD cards, tried formatting them all with different cluster size. I've even downloaded older upgrade.scu files with the same results. My card is a Supercard miniSD. Looking at the back of it I can see there's a Hynix 519AA chip and a CB O441 chip. Maybe the people who are having problems have similar chips (because I know there are different parts depending on when the cards were manufactured) Keep posting so we can get this resolved!
