@evansauve I would check out @ExarKunIv awesome archive of extra games for retropie. He has a script already setup to install this game without having to do everything manually.

https://github.com/Exarkuniv/RetroPie-Extra

Follow the instructions on there and then you should be able to install openrct2 right through the retropie menu

I played this on that eltech desktop thing when they had me do a demo trial last year, it actually worked great under that thing. Probably the only thing I tested that did run well.
