How to do to extract 7z files before to launch only in Retroarch PSX core and not in the anothers cores like Arcade??

If I activate the option "extract file" in Retroarch emulator for use with PSX core it is also activated for the other cores that need to launch compressed files to work fine, such as FBA or MAME.

Set up a 2nd emulator entry in LB with the option to extract rom unchecked. You don't need a 2nd install of Retroarch, just a 2nd entry in LB and point those arcade games to the 2nd emulator entry.

I had just thought about doing that too and now it works. Thank you
