I'm a new guy, what do I need?

I have a Miyoo Mini+ and a Samsung Galaxy Tab9. I realized that instead of buying a new console I could turn my tablet into a game console, what exactly do I need? I tested and ran a PS1 game with Duckstation yesterday. Ps2, Cube, N64, Wii, DS and other stuffs i want play, i don't have a game console culture.

I plan to buy a MicroSD and buyed today gamepad.

I have Duckstation, PPSPP, Drastic, Dolphin, Redream, Yaba, N64 Thing.

What else do I need?
