Ok, I have my GBA emulator downloaded and all, but when I go to download this, It says To find it, save it, or cancel. So I pressed find it, and it said that file didn't exist.

And also once I get a ROM saved to my computer, how do I use it on the emulator? Thanks.

1) Save the Pokemon ROM to your computer in a location your remember.
2) Once its downloaded you need to download 7-zip or 7-zip portable
3) Install that and use it to unzip the downloaded Pokemon ROM from the location you were supposed to remember
4) Open your emulator and go to file --> Open (or something like that)
5) Then you need to find/browse to the place where you unzipped the rom to and open it
6) BAM - Game should load up

Let us know if you have anymore trouble

I downloaded 7-zip and tried to extract the files, but it still says the file isn't there. And when I tried to play it on the emulator, it said it needed to be unzipped.

try redownloading the rom or use a different emulator

You will need to UNZIP the rom from the 7z file. You can download 7zip to do this.
