installing retroarch on steam

Retroarch gets installed to ~/Library/Application\ Support/Steam/steamapps/common/RetroArch I had to disable the PS5 button support in mac to get it to work inside retroarch Retroarch also picked up my controller as #2 instead of #1, and I had to flip it in settings I had to disable the steam overlay to get the ps5 button working in retroarch guide here telling you how to get the cores, which are not built in doesn't work on OS X though steam has some DLC cores, so I installed the Beetle PSX DLC that got close to working! But then it failed on the firmware, so need to figure out what dir to install it to cp SCP* ~/Library/Application\ Support/Steam/steamapps/common/RetroArch/system got it going
