Hey, a fellow gunter!
You could check this out: https://play.google.com/store/apps/details?id=com.explusalpha.A2600Emu&hl=en
And then get some roms of hits like pitfall , joust, missile command and you are ready to go.
Obrigado for your post, for reference here are the links to the emulator apps you show:
I've been researching to see which ones to get to put in my Nexus 9, I'll try all of the ones you used. If anyone recommends any other let me know.
Edit: Added NES.emu, comment on ads on the "John" emulators.
