More news on the horrid release, heres what Drunken Coders Posted:
A day or so ago, Darkfader released a certain malicious bit of homebrew under the name r0mloader. This software claimed to allow a person to run commercial roms off of their GBAMP or supper card. What it actually does is corrupt the firmware on your DS as well as on your supper card or GBAMP effectively turning your DS into a brick.
It is suspected that this was done as an act of anti-piracy but it has caused many beginning amateur programmers to shy away from the system. Although I tend to fall heavily on the anti-piracy side of things myself, I do not feel it is the homebrew communities place to take such actions.
Fortunately the first thing most people do when the set up their DS for homebrew is apply Firefly's firmware patch. Unlike Nintendo’s firmware, Firefly's patch has recovery code built in which allows you to restore your firmware if you have a gba flash cart.
If you do not have the firmware patch applied be careful of what you run. If it is already too late it is still possible to recover although it requires a bit of effort.
I am not sure how wide spread this is, feel free to email me if you were affected and I will work on getting a recovery guide posted.
