Mame only recognizes 16 buttons

[gooz74]

Lika a lot of people here I have made a 2 player bartop arcade cabinet and for the controls I have 2 sticks, 6 buttons / player, a coin button and a start button / player and a left and right flipper button.

In total, this is 2 sticks and 18 buttons where for player 2 the start and coin button are button 17 and 18.
When I was configuring Mame I noticed that Mame only recognizes 16 buttons where in jstest, all buttons are working.

My cabinet is running on Retropie 3.3.1 and my buttons are running with “THT THT Arcade console 2p USB Player”.
Can anyone help me to get the not working buttons recognized in Mame?

I thought we had fixed the button limit already with 3.3.1 – however for now maybe you can try advmame or a libretro core if it doesn’t work.
