Resident Evil 3.5 (Hallucination Version) - Gameplay Video (E3 2003)
Remastered in 4K using ESRGAN [AI Machine Learning]

ESRGAN is an AI Neural Network software that is capable of upscaling and reconstructing low-resolution images, while retaining most of their elements and details intact.
I took the original video file from the Biohazard 4 Secret DVD disk, and used ESRGAN with alsa64's denoising model [JPG (0-20%)] and the Manga109 model to upscale the video 4 times its original resolution.

In order to reduce the aliasing and motion blur, I tried to apply various filters (like Nnedi3, QTGMC and FFT3DFilter, etc). Obviously, the gameplay doesn't look like native 4K, but it does look noticeably sharper (it could even pass for a 720p PS3/X360 title).

Original resolution: 720x480
ESRGAN Upscale: 2880x1920
