Yep. I didn't have an R4. I bought 2 R4 previously on Ebay and couldn't get them to work. But I had an SD Media launcher that I bought to back up my Japanese Colosseum save when I beat it. My friend was also able to backup his saves so we used to send eachother rare Pokemon by trading Pokemon to Colosseum and sending eachother the save. He got the Fire Red cart on Ebay and sent me clones of his Pokemon.
I had no idea my Celebi was so rare.
