I’m kinda lost on the best way to do some retro gaming on OSMC… Dual boot or use an emulator? If an emulator is there one built in to OSMC or is this an add on. There seems to be a bunch of old info just not sure what to follow and where to find the best answer.
No need for dual boot.
You can try the Kodi Build in Gaming Emultators but they are a bit hit and miss. If you want a more broader solution go for retrosmc / retropie
