Which Emulators work?

[Enderess]

I know that Retro Pie provides specific emulators that work. I was wondering if you can put other emulators on or change them to work on the system. Thank you.

@Enderess If you know how to get them working on the RPI etc. Requires some development knowledge.

I have some developmental knowledge however limited, thank you for your assistance. I am making a console with two linked Pi Zeros, two analogue sticks, one dpad, a,b,x,y buttons and shoulder buttons. I am hoping it is going to be good as it has superior Processing power to all consoles it will emulate but ram might not be so good.... Thank you again

[Enderess]

But which version of the emulator would be best to start with, MAC, PC, or Android?

@Enderess You need an emulator that is open source - preferably for Linux.

Thanks again.
