Here is a massive 4 way comparison of several ports of Resident Evil 1. As always, you must watch this video with annotations to get the platform labels.
Here's the full screen raw videos of each platform

PS1 version is the Director's Cut Dual Shock Edition, running on my PS3 through S-video cables at 480i to stay authentic. Sega Saturn is running on actual hardware, with S-video, at 480i. PC version is running 640x480 and was direct captured with OBS. Only the Nintendo DS version is running on emulator to make direct capture possible, however I have it running at the DS native res of 256x192, and captured it at 480p via OBS.
Generally, top left is PS1, top right is Saturn, bottom left is PC, and bottom right is DS. The soundtrack switches between the versions to show various differences, such as the new Director's Cut Dual Shock edition OST.
As I said, watch this with annotations ON in order to see which version is which, and which soundtrack is playing. Hope you guys enjoy!
