Overview

• LenOwO user minki ran Doom on an old PDA powered by a DIY 18650 UPS connected to a router’s USB port for a constant 5V supply.
• The game failed only hours past the two-and-a-half-year mark when the demo-tracking variable exceeded its integer bounds, aligning with minki’s prior estimate.
• PC Gamer reported the result on September 17 following minki’s September 16 post, with PCWorld subsequently covering the test.
• The outcome underscores how long-running counters in legacy engines can overflow and cause deterministic crashes far outside normal playtime.
• Community commentary pointed to similar multi-year timer overflows in Crash Bandicoot 3, Final Fantasy IX, and Paper Mario.
