Retroarch 9000 Roms | Verified

First, I should clarify that RetroArch itself isn't pre-downloaded with ROMs. Instead, it acts as a platform that connects users to various emulators and cores (which are the actual emulators inside RetroArch). So the "verified" aspect might refer to compatibility between the cores and the ROMs. Maybe users test 9000 ROMs with specific cores to ensure they work.
