It's not as widely known, or as easily available from rom sites, but the version 0 of the game has a few exploits many of the top runners are able to utilize in the run. Most notably - the FPS section dinos have smaller collision boxes that let us just pass them by in areas that the Rev 1/A does not, for example the dilophosaurs in the raptor pen B1 at the door after the elevator, the one next to the NVG battery and the one just before the floor meat can all just be passed by running along the wall/door next to them. In Revision 1, these specific dinos are impossible to pass by between them and the walls.
In terms of hardware, the version 0 cartridge can be identified by the Made in Japan on the back of the cart/box, revision 1/A has a Made in Mexico/Assembled in Mexico instead.
I am unable to confirm that at this time. When I had it, I only was testing for the NES version but refunded it because I could not adjust the controller layout. I would assume that it would be version 1, and the above examples would be a very easy way to check or by jumping out from the top of the ship to an invisible platform that's only in version 0 
The classic collection is a Rev 0 rom It was modded to remove actor portraits and remove the Kenner Toy Company Logo from the game and recolor health packs with a green cross instead of the red cross everything else is the Rev 0 rom file
When you are on PC you can use the rom file even in a normal Emulator instead of the emulator of the classic collection
