Gran Turismo 1 Demo GS Codes - Arcade Mode cars Unlocked

Yes, I have a few gameshark codes for my Gran Turismo 1 demo. As far as I know, this one only works on the Playstation Volume 9 Sampler disc. I could be wrong though. In this video, you'll see every car playable in arcade mode as well as a couple of secret cars hidden in the disc.

This should be a fun game to explore. I also do a race on High Speed Ring again since I still can't access the other courses, I'm going to try to find codes on my own this time. I would like to thank Hacczilla once again for providing me with the unlock cars code. Anyway, I do a race with a slower than usual Racing Modded Subaru Impreza WRX Sti. Enjoy the video.

Cheat to do this:
Note, this is for the Interactive Vol. 9 PS1 Sampler Disc. All thanks to the user Hacczilla.
