when I want to use DeSmuME play a game on vnds,it shows me this error('libfat failure'),so I have to 'make sure it(emulator) supports DLDI and that it's activated',but I can't find what's wrong , and after I readed the FAQ , I only got to know what is DLDI,but not what to do.
If DeSmuME doesn't supports it,is there any emulator supports?

I must say sorry for my poor English,but I really like this NDS emulator and I want to solve this problem.

Thank you!
