Settings → Emulators shows what’s available to you. Emulator updates can change how games launch, so include the emulator’s name and version when you report a problem.

Before using an emulator

• Open the emulator once to finish its own setup.
• BIOS and firmware are read by the emulator, so set them up there.
• Vita3K: Games must already be installed in Vita3K.
• Dolphin multi-disc games: With an M3U list, RetroMao passes the discs in list order.
