Help with game

[Zaphkiel]

I haven't touched my DS in about 5 months and I just recently heard how good Sonic Dark Brotherhood was. So I got it and my DS won't play it.

My guess is that I need to update the cfw or something so would you kindly? Thanks! :D

The only "custom firmware" for the DS (at least the only notable one still in use today) is FlashMe. Updating that won't do a thing, as the firmware does little in terms of actually running your games.

If your Sonic cartridge is not working, return it to your game store and get a replacement.
