Under the microscope: Small Soldiers (PlayStation)

Rings of Saturn • 14 implied HN points • 11 Feb 26
đź•ą Technology Software
  1. The game packs eight button presses into a 32‑bit value (X=0, Square=1, Circle=2, Triangle=3) and extracts fields for starting level, difficulty, three ammo bits, and a checksum; the password is valid if the checksum equals the sum of the other fields and the values are within allowed ranges.
  2. Because the checksum is just the sum of level + difficulty + ammo, you can generate every valid level password programmatically; the three ammo bits map to the Rebound, Star Bolt, and Big Blast weapons, so a small script produces a complete set of passwords beyond the common Normal‑difficulty lists.
  3. There are static special passwords that trigger cheats (movie, invulnerability, all weapons) and two undocumented codes — one plays the staff credits, and the other, if entered twice, opens a cheat screen to pick starting level and toggle invulnerability/weapons; the full generation script is on GitHub.
