Wow, what a great project! It was really for cool projects like this that the port was intended for.
I do plan on porting Cash Cow DX over next, this time with native arm32 and arm64 builds, which should run on RetroPie and Batocera as well as most Linux arm based SOCs.
If that works well enough, I'll do the same for Donut Dodo.
Thanks so much for sharing!
