It might even be possible to get them from DS games if you can extract a savefile from an R4, but I'm not sure if you can. If the savefile is directly on the rom, you'd just have to get them from fire red to your R4 gen 4 game, then remove the rom from the R4, put it on the computer, start it on an emulator and extract the save with the emulator.
If it's stored somewhere else I'm sure you can just get the savefile manually.
Then when you have your savefile you use PKhex to extract the pokemon files.
Of course you need to own a physical copy of said gen 4 game otherwise this process would be illegal teehee
