Emulators on 3DS

Since the 3DS homebrew exploit, provided you can do this exploit, you can install a variety of emulators taking advantage of the hardware.

Multi-System

Retroarch

There are preliminary 3DS ports of the Gambatte, gPSP, and Genesis Plus GX cores, though Audio needs to be disabled everywhere on risk of crashing.

Consoles

NES

• 3DNES

SNES

• blargSNES

Handhelds

Game Boy

• GameYob: GB/GBC emulation.

Game Boy Advance

The 3DS does include natively a firmware for a GBA mode, used for the ambassador releases. But its compatibility is a hit and a miss, missing features, and its software mode actually runs very slow.

Some homebrew apps do real GBA emulation on the 3DS:

• 3DSGBA
• CitrAGB

Others

CHIP-8

• CHIP-3DS

VC Injection

Some have tried injecting alternate ROMs in the available Virtual Console releases (MD, GG, NES, GBA Ambassador, GBC, Japanese emulated SFC compilations) with varying degrees of success. VC emulators for Sega systems in particular have high compatibility.
