I'm currently trying to set up RetroArch with LaunchBox. The SNES/Genesis roms went well for the most part, but now I've got about 10-12 gamecube roms in my launchbox library and it's saying i'm missing the core files to the dolphin emulator. i've got the actual dolphin emulator installed on it's own, and i've tried to download the cores. the only difference is that it pops up in retroarch but not the 'cores' file in my file explorer (see pics for reference). any idea what the deal is? edit: yes i've 'downloaded' the gamecube/N64 cores, but they just won't show up in my file explorer. they only sit there (first image) likeso and when i click on them, nothing happens.
