Ok so this is not necessarily for neuro to play games competently, but if you have a generic interface (neuro does mouse, keyboard, controller inputs) and vision I wonder if you can get some content.
Like for example, neuro would be bad at fighting games in theory right? But like if you queued inputs they could sort of play in a mashing style with a rough general idea of past positions. So they might be bad at a bunch of games out of the box, but the upside is they could play a bunch. Different than neuro sdk, but maybe this could provide variety and maybe there will be a couple games that they end up being able to play.
give lil bro the controller and see what happens, and if it doesn't work out move on to the next game. so you can have games lined up and play them one after another.
