Help with buttons on rpi 4 retro pi arcade build

[captin]

Hi all, new to the forum, so please be patient with me, and my noob questions.
I am a building a bartop arcade for my raspberry pi 4 retro pi, i was going to go with the six button layout with player one button and select on the top. is it possible to put buttons on the sides for pinball games, and how or where would i put the coin and exit buttons, is there any links for help to map these or help with the set up. thanks for your replies and help.

By default, select is used as coin input by most arcade emulators, but you can also have a dedicated coin button. Same thing with exit, most emulators accept a button combo to exit a game (see here).

To map the buttons, you'll have to use each emulator's specific input configuration - additional buttons are not supported by the EmulationStation's input mapping dialog. If you specify which arcade emulator(s) are you using (or intend to use), then we may be able to give more specific info on the actual configuration.

@mitu Ok i will look into the games and see what emulator is being used. Iv started building the cabinet, and am gonna go six button layout with one player and coin and two player and coin on the top face, then one button each side for pinball games. I see people have built them with another two buttons on the front side, but i dont know what they are for, so i will leave them for now. Its getting cold in the uk right now, so being in the shed is murder, i just wanna get the thing put together and get it in the house so i can figuer the rest out, without freezing hands and feet. thanks for your help though.
