Emulator Failing

Im using No$GBA 2.6a. I opened up the No$GBA file and searched for my heart gold ROM. When I clicked on the ROM, this is what it said that it either was a corrupted file or it was not compatible with the emulator which is not true. I downloaded the ROM off here. Anything that I shoud do?

Did you extract the game from the RAR file?Here is a Tutorial for WinRAR
