Nothing interesting.
Haven't played TTR in like half a year but had this laying around.
It's byte patching their anti speed hack time scaling.
Speed hacking can be used to race faster, faster animations (but you can't go too fast for animations), run faster, fish faster etc.
If you want to find it yourself open up TTREngine64.exe on IDA and look for use cases of string "Force-adjusting time_scale to catch up to" as seen in the first couple seconds of this video. One of the smaller code blocks below it is what scales the time and should be patched.
Don't really use windows much so I don't really game much so I don't really write hacks much anymore.
