So I've been trying to find a ROM for HG/SS but I can't seem to find a good one. Any recommendations?

Like the title says, I've been trying to find a ROM for HG/SS. I tried downloading one about an hour ago but then my computer crashed and took forever to restart. So I deleted that file and my computer is running fine again. Can anyone help with finding a decent ROM for either of these games? It would be greatly appreciated!
