Thank you very much for this tool Pokedoc! I had been hearing rumors about people trading pokemon that would corrupt your save files, and didn't want to chance the GTS again without a way to back up the files.
EDIT:
Just noticed you have GBA backup support, so I tested it:
GBA read and write support confirmed working with Ruby and Fire Red.
