Under the microscope: Urban Chaos (Dreamcast)

Rings of Saturn • 58 implied HN points • 29 Nov 25
🕹 Technology Video Games Reverse Engineering Open Source Software Development Game Development Console hardware
  1. The Dreamcast build has hidden "fast cheats" you unlock by holding L+R and entering a specific button sequence (stored backwards as "Y R R A B Y R R A B"). Once enabled, hold L+R+Start and press Up/Down/Left/Right to restore health, spawn guns, spawn ammo, or show the character's position.
  2. There are several other in-game codes: one (A,B,X,Y) shows a silly message, another completes the current stage, and another toggles draw distance which you adjust with the analog stick. A few strings referenced in the source (like LARALARA and BLADDUR) are present in code but don’t work in the final release.
  3. Access to the game's source code (and simple reverse-engineering) is what revealed these cheats and how they operate. The PlayStation version doesn’t appear to include the same in-game cheats, though it does have a separate "all levels" cheat available from the menu and shown in source snapshots.
