Had problem remembering the control scheme, so I made some funny mistakes like money shift & accidentally pulled my handbrake on the main straight in Race 1... lol
But anyway! This is the full race of GT World Cup in the OG Gran Turismo (NTSC-J version) including qualify sessions!

DuckStation configs are mostly default, I only tweaked Z-Buffer emulation so the tachometer needle doesn't freak out. (Yes it's a 3D mesh on the HUD.)
This video is a raw output from OBS Studio, nothing edited.
