I’ve modded an A1up but now I’m modding my Run n Gun/TMNT cab.  I started tonight gutting the cab.  I’m outside Raleigh, NC and bought this cab in college.  It’s been through 3 apartments and 2 houses and it’s time for an upgrade.  I removed the working CRT, the marquee and all controls in the CP.  my plan is to drop a Pi4 in it, add a few buttons, add a led to the marquee, add coin buttons to the coin doors, and add new joysticks with upgraded springs.  Few questions, which buttons does everyone like using for a 4 player build and what would be some sweet themes to rewrap this cabinet?  Thanks for being understanding with the dumb questions.
