Thrillville: Off the Rails

Open Cheat Engine, go to File > Open Process and double click Thrillville.
Change Value Type to Float and search for:
5:4 = 1.25
4:3 = 1.3333
16:10 = 1.6
16:9 = 1.7777
Once you've made the first scan change the aspect ratio in the options, and this time do Next Scan with the aspect ratio you selected.
If the first address is green add the second one, if not, add the first one in the results. Change it's value to the desired aspect ratio. (e.g. for 21:9 I would enter 2.38) http://www.wsgf.org/article/common-hex-values

Not all menu elements scale properly, but it's only cosmetic. (Fades, backgrounds, etc.)
Certain mini ("party") games have issues that can affect gameplay.
In Bandito Chinchilla the left of the screen can be cropped off.
FMVs are pillarboxed.

TH2Go is not natively supported. The game identifies it as 16:9, and stretches a 16:9 ratio across the TH2Go resolution.

Ultrawide hack should work for other aspect ratios as well.

Cursor is tiny.
