How can I install Genesis en TurboGrafx cores?

Hello,
I would install over cores to play Sega and NEC games.
What’s the way to follow ?
Thanks.

Genesis Plus GX doesn’t run well on this device, and picodrive crashes immediately.

If you are deadset on playing some sega, you can install Genesis Plux Gx by going to Retroarch > Load Core > Download Core > genesis_plus_gx_libretro.so
