So, I got my Cocktail Table built in the standard 2 player head to head style with 8 buttons on either side for game play, 1 player, 2 player, escape, and coin buttons on one side. I bought the joystick/button kit from TimeHarvest and it came with this THT Arcade Console 2P USB controller. Everything almost works. It won’t register button 7 and 8 on the 2 player side or the coin and escape buttons. I think if it was working, they would register as button 16, 17, 18, and 19 in MAME. I thought I might have a ground wire issue so I plugged it into my windows laptop and they work fine. MAME on RetroPie won’t register them at all. Any suggestions? Been searching the internet for hours to no avail. Doesn’t look like a lot of people are using these things. I attached the boards layout. Thanks for any help!
So, I figured out finally that THT Arcade console 2P USB Player is the same thing as Xin-Mo Dual Arcade. Once I started searching for Xin-Mo information I finally found lots of people having issues. I went ahead and installed an image of Raspicade since they claimed it is supported and it works fantastically. This is a USB interface for up to two arcade joysticks and 22 buttons. I guess I am really pretty confused as to why this doesn’t work right with RetroPie. I will await patiently for replies.
Here is what my extremely unconventional way to get it to work was. You see, apparently, the MAME emulator itself is the issue as it will only assign a maximum of 16 inputs per joystick. There is a guy out there with another project called retrocade that recompiled the mame4pi somehow to get it to work. I say somehow because I couldn’t for the life of me figure it out. Since I personally like RetroPie better, I did the following.
1 Get yourself 2 SD Cards
2 put image of RetroPie on 1
3 put image of Raspicade on another
4 boot pi with raspicade image
5 Now, you can configure raspicade to work, but that isn’t our goal. So exit the front end to a console prompt and then terminal into raspicade from your pc and copy the entire mame4all-pi directory
6 Now boot the Pi with RetroPie
7 Again quit emulation station to a console prompt
8 Go to your pc and replace raspicades mame4all-pi with the one you copied before the location is /opt/retropie/emulators/mame4all-pi/
9 Now you need to edit the directory section of /opt/retropie/emulators/mame4all-pi/mame.cfg to look like this. Make sure you have permission to save.
