Crackling crust, pillowy middle. The kind of bagel that earns a second cup of coffee.
Summary
A detailed technical post-mortem of creating a mod for Deus Ex (2000) that fixes broken lipsyncing and blinking animations that had been bugged since the game's original release. The author explains the technical detective work involved in identifying the root cause (a missing conditional check in the game's native code), reverse-engineering the game's animation system, and implementing a fix using DLL injection and assembly-level patching. The post covers the game's original lip-sync system, the bug's history, and the modding process.

· 3 pulledI guess I was playing DX1 and thinking, geez, was this lipsync always this bad? In a weird way? It's insta-snapping mouth shapes, but they're not always the same mouth shapes. Is this broken?
Everything I wrote about it is on Twitter, and it oughta be somewhere else, so here's a post about it.
The mod itself can be downloaded here.
