Lol I want to buy the game fair and square. I just wanted to know if it can be downloaded like the remake on steam.

I know this might sound ridiculous but I just recently started learning how to Speedrun RE3. It's one of my favorite games of all time, I've been practicing it on emulator and I'm trying to purchase a PC port but I can't seem to find a legit source for it. I'd like a downloadeble version vs a physical copy if possible.Any help would be greatly appreciated thanks.
