GTA San Andreas Speedrun - Any% (MDvMMw/CE) in

⬇️

MDvMMw/CE stands for "Mission Duplication via Memory Manipulation with Cheat Engine". We use a software called "GTAOnMissionChanger" instead of Cheat Engine, just because it's much more convenient and does exactly the same thing.

The main point of this category is to swap the variable "On Mission" value between 1 (on a mission) and 0 (not on a mission). This value is displayed on screen all the time during the run just for information.

When you start a mission (On Mission = 1) and swap this value back to 0, the game allows you to start it again, and by doing that, you complete 2 missions in 1. This is what we call a "dupe".

Some missions can be started more than twice if possible, skipping even more content.
E.g.: When you start Tagging Up Turf 3 times, after finishing it, the game considers you completed 3 missions from Sweet's chain instead of only TuT. Therefore, Tagging Up Turf + Cleaning the Hood + Drive Thru are completed.

More information about mission chains here: https://kb.speeddemosarchive.com/Gran...

However, not every mission can be "duped", some of them crashes the game (Catalina ones) or just causes a "softlock" (e.g: if you skip The Green Sabre, Badlands is never unlocked).

If you wanna learn this category, I highly recommend this tutorial made by English Ben. There are some small optimizations here and there nowadays, but his tutorial stands very much relevant for a beginner to pick up.
