As of this time Resident Evil 0 never had a release outside of Nintendo. It was a GameCube exclusive following the Remake in 2002 before being ported to the Wii. Fun fact: it was originally going to be released for the Nintendo 64, but all the data wouldn't fit on a cartridge so development moved to the GameCube.
I imagine this could change soon depending how well the Remake HD port does in sales.
