There's a "Work In Progress" version of Porsche Challenge for PlayStation on the Euro Demo 14 disc. It's a "rolling demo," i.e. it's not playable. But if you flip the right bit, you can take control of the Boxster.

I made a patch that makes the necessary change to the game data. You can download it from GitHub.

There's no technical writeup on Substack for this mod, but you can hear me lead a discussion about prototype builds on demo discs on a recent episode of the Hidden Palace Podcast.

There are cheat codes for Dynasty Warriors on PlayStation, but some of them require you to complete the game before you can enter them. Is there a way to cheat more effectively?

Yes – the game has an "unlock almost everything" code that's remained secret for 29 years. I found it hiding in the game data.

Details on the code and how it works are in the Substack article.

Luxoflux developed three games before being acquired by Activision in 2002:

• Vigilante 8 for PlayStation and Nintendo 64

• Vigilante 8: Second Offense for PlayStation, Nintendo 64, and Dreamcast

• Star Wars Demolition for PlayStation and Dreamcast

I reverse engineered the cheat systems for these games and found new codes for all three! Details are in the Substack post.
