DoxBox does IMO work well on Android but it's clunky to set up - you likely need some variant of a "hacker keyboard" installed to make initial setups easier for games, and then AFAIK you'll probably need to also install another keyboard of choice that supports the buttons your game needs. All in all it likely is worth it for some games if you're nostalgic enough for them but don't feel like playing them when you're at your PC. I've had more success playing old PlayStation games, personally (on ePSXe these days but I've used RetroArch in the past, which I should probably look at using again).
