Dirt 2 (U)- Help

So I tried putting dirt 2 on my DsTTi and it gives me the error code saying save file not found. I first tried to reformat my card but that didn't help. I upgraded to 1.17 as well as trying to do arm7, but nothing has helped. Should I just give up?

You need to have the filename of the ROM have more than 8 characters, and/or no spaces. It's a firmware bug.

thank you. It worked.Mods please close?
