Pokemon gen1recomp might be the best and well supported game for external display
Although I haven't thoroughly tested it, it seems to run well right out of the box without any configuration.
I was looking for a game I could casually pick up that wasn't just arcade-style and had a sense of progression. After a disappointing experience with chess.com support, this really seems promising.
I'm also sure you can improve it 10x with some moddind and tweaking around.
Kinda wish you could use the external camera as A & B buttons 😅.
