NO$GBA +POKEMON DIAMOND-HELP PLZ

Hey
I was just wondering about Pokemon Diamond because I downloaded the rom as well as the NO$GBA emulator, but when I extract and try to pull the rom onto the emulator, the screen pops up with a message "The data could not be read. Please turn off the power, then remove and reinsert the DS game card." Is it me or am I being clueless, reinserting a game card is not possible because this is not the ds console...so what can I do? Just wondering if anyone has this problem if they have played this game. Any help is appreciated. Thanks.

Yes, so many others have had this problem that we decided to cover it in the Common Issues thread, you should read that before you ask a question.

Just go into Its settings & change nds memory from none/auto to FLASH256 Kbytes . It'll play like brilliant

ahhhh i finally learnt that u have to save through the normal ds menu to save but now when i try load my saved game i just get a big black screen. pleasssssseee somebody tell me how to fix this :'(
