How to enable speed control in Yuri's Revenge campaign

It’s been ages since I last played Yuri’s Revenge. It brings back fond memories such as playing skirmishes against my father in an internet cafe at my hometown.

Recently I started following tgSacred channel and the edited campaigns look so interesting that I want to try it myself.

After I downloaded and applied the edited campaign (whose walkthrough is published at this playlist), I found that I can’t change the game speed of the campaign. The default speed is just too slow to keep a normal player engaged.

Some Google search brought me to this post. First I tried to add the -speedcontrol option to the shortcut which didn’t work. I suspect it was because I have to start the game through Origin, which meddled with the settings. Then I switched to the hex editor option which I didn’t have much faith in due to how crude the approach is, but it worked!

Being someone who became a programmer in his 20s who missed the early days of programming, I was quite fascinated at how the modification of the binary (or hexidecimal) codes of a Windows game could reveal a hidden option.
