Rom Help

OK, whenever I try and play the Pokemon Platinum Rom it wont work. I mean, that when I open my emulator and try to open the game, the game is not there, but it is in the folder before I try to play it. Idk what I'm doing wrong? This isn't my first Rom so I understand what to do. I am a little confused on whats wrong though. If anyone could give me some advice that would be great.ThanksFYI: I have both VBA and No$GBA V2.5

You need no$gba 2.6aDid you extract the .nds file from the rar arcive ?Have a look hearhttps://www.romulation.org/forum/index.php?topic=31241.msg546113#msg546113

I downloaded the no$gba v2.6a, and it still does not work. Any ideas where I can find a zipped file of the Rom?
