Basically for now you must hold off trying any new homebrew unless you can guarentee 100% that the person supplying it is safe:

DarkFader, the person who cracked the Nintendo DS, was behind the creation of the NeoFlash, the MAN who ran the Nintendo DS ROM release group GST (Golden Sun Team) has released a small program that will erase your Nintendo DS firmware, GBAMP firmware and/or your SuperCard Firmware and the release appears to be supported and endorsed by the DSDEV (#dsdev on EFNET IRC) community of dev's (who most recieve free NeoFlash devkits). This Bricker does not destroy NeoFlash carts? Could there possibly be any correlation?
The code used in the original bricking application has been ripped and now is being added to other homebrew and roms so if you run one without checking it first you'll end up with a dead Nintendo DS, GBAMP and/or SuperCard. This is a very counter-productive move on the Nintendo DS's Development Community as their code to disrupt piracy (which they helped create) is now being used in their own programs! Currently there is no way to test for this bricking code!
Just image going to run NESDS and having your Nintendo DS die! Luckily, if you use the FlashMe Firmware replacement for the Nintendo DS you can recover from this deadly attack by booting up the system any holding "A+B+START+SELECT" then loading the Firmware from a flashcart other then your SuperCard (as it's most likely been destroyed).
