Is an N8 needed?

If you’ve purchased an Everdrive-64 X7 which has NES emulation, do you even need to get the N8? Are there capabilities for NES games that the N8 has but the 64 X7 doesn’t?

UPDATE: I just got the 64 X7 today. All games seem to play great, including the NES and even Hydr8gen’s sodium64 emulator for SNES plays well. Only bug so far was the system freezing when I played Super Mario Land on GameBoy emu once I got to the end of the second level.

That said I do recognize the cheats are meant for GameShark codes, so I’ll look into the other EDs for NES & SNES.
