Unimplemented BIOS Call Pokemon Radical Red

I was playing Pokemon Radical Red without a BIOS and randomly got an error saying "This game uses a BIOS call that is not implemented. Please use the official BIOS for best experience." I've got just under 9 hours of play time on the game with no issues until now. I have tried to use the GBA BIOS but wasn't able/don't know how to transfer my save. Save State 1 (my latest save) has this issue but Save State 2 (a lot further behind in progress) works.
