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!

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.
