EmuVR is just retroarch, so yeah you need matching bios and roms. Videos are the only thing that the host can have without anyone else needing as they'll just download that directly
If someone joins without owning the rom then the host gets fucked over and has to restart the game to play it again. So before inviting anyone to join you just make a pack of games to share or use mine https://mega.nz/file/gQQEwBiT#uZW3UlsynGT1bqsa3CywGX4JDMxYTW_TVPG21HZJCUM
