Alrighty, I'd like to help you.
Just follow my instructions:
1) Go to the ShinyGold page; here's a
link.
2) Scroll down until you see "Attached Files."
3) Download ShinyGold_V4(bugfix)_ByZel.zip if you want the normal version, and download ShinyGold_X_V4_ByZel.zip if you want the hard version.
3a) Now, take the zip file and unzip it using any program, and you get a ips file. Leave it there, and move on to the next step.
4) Now, you need a FireRed rom.
5) Once you get one, take the rom and the ips files and put them in one folder.
6) Now, name the rom and the ips the same thing...
7) Now open the rom in VBA (VisualBoyAdvance - If you don't have it, google it)
8) BAM! ShinyGold is on your computer!
Have fun!
