I finally managed to find the long-lost NES version of BioHazard. Yes, Dot, grovel at my feet as I release it to the public and enjoy that fuzzy feeling of doing something good without reward
Although BH NES was never official Capcom, it was official anyway to some Chinese company. It's not, I repeat not fan-made.
You'll need an NES emulator like Nestopia (Here), and the ROM is very prone to crashing, so remember to use those save states! (F5 in Nestopia.)

(P.S: Just kidding about that grovelling thing, Dot )
