Emulators on 3DS

From Emulation General Wiki
Jump to navigation Jump to search

Because of the homebrewing scene the 3DS has had, you can install a variety of emulators. Currently, the New 3DS is capable of running much faster than the older models, making it a much more ideal platform for emulation, but despite this there are still some emulators that have issues regardless.

Multi-System[edit]

RetroArch[edit]

There are preliminary 3DS ports of the following cores:

  • 2048
  • CATSFC
  • CATSFC Plus (has more accurate audio, slower)
  • FinalBurn Alpha CPS1
  • FinalBurn Alpha CPS2
  • FinalBurn Alpha CPS3 (most games are too slow to run even on New 3DS, though JoJo runs almost full speed)
  • FinalBurn Alpha Neo Geo (A few games are unable to be loaded due to memory constraints)
  • FCEUmm
  • Gambatte
  • Genesis Plus GX
  • gpSP (dynarec only works by installing the CIA)
  • Mednafen NGP
  • Mednafen PCE Fast
  • Mednafen VB
  • Mednafen WonderSwan
  • mGBA (acceptable with Pokemon Ruby/Sapphire, but some games are slow to use, even on New 3DS, at present)
  • Nestopia
  • NXEngine
  • PCSX-ReARMed - the latest nightly build has made some improvements, making it possible to have 60 fps emulation on some games (mainly 2D based games, but is possible for 3D games if you tweak some of the settings) and even added support for .CHD compression formats. These improvements are mainly for the New 3DS as the original model is not powerful enough.
  • PicoDrive (32X emulation does not work in the .3dsx format, at least.)
  • PocketSNES (less compatible than CATSFC, but can actually run many special chip games at full speed)
  • QuickNES
  • Snes9x-Next (too slow to use even on New 3DS at present)


Using current exploits, the New 3DS is capable of running most of these cores at or nearly at full speed on most games. The only cores the older 3DS can reliably run at full speed are 2048, Gambatte, QuickNES, NXEngine, and some older Sega games using PicoDrive. Opposed to normal use of RetroArch, these are all self-contained emulators, albeit sharing the same automatic configuration. Screenshot-taking is broken. Upon exiting RetroArch 3DS, press the Start button.

Unofficial Builds[edit]

There are unofficial ports which add new cores with emulators that do not have a retroarch by default

Consoles[edit]

NES[edit]

SNES[edit]

  • Snes9x for 3DS - runs a good majority of games well, even on old 3DS/2DS's. It's recommended to use a New 3DS if you want to run games that uses the SuperFX or SA-1 chip properly.
  • blargSNES - It works well, but lacks compatibility for games with certain chips (i.e. the SuperFX chip).

Genesis[edit]

Handhelds[edit]

Game Boy[edit]

  • GameYob: forked from a popular emulator used on the DS. Emulates the Game Boy and Game Boy Color.

Game Boy Advance[edit]

The 3DS does include native firmware for a GBA mode which was mainly used to run ambassador releases instead of having to develop an emulator for them. So far, the only way to access this firmware is by injecting a GBA ROM as a VC application. This can be achieved through various programs such as this one. Compatibility is high with the exception of cartridges with special hardware. The only downside is it can't provide features that are normally available on other emulators, such as savestates, screen filtering, or sleep mode, since technically it's running a "virtual" GBA. Also, each ROM must inject and install individually including the save files. If you're using an old 3DS/2DS, this is the best option to play GBA games.

On the other hand, there are also some homebrew GBA emulators available for 3DS:

Neo Geo Pocket[edit]

NeoPop

Nintendo DS[edit]

DeSmuME - an experimental port of DeSmuME that has since been abandoned, it wasn't very compatible.

TWiLight Menu++ - Not technically an "emulator", rather it's a frontend for a seperate program, nds-bootstrap, which allows for an NDS ROM to be loaded from an SD card. It utilizes the virtual DSi (aka the TWL_FIRM) that the 3DS has for backwards-compatibility, meaning this program can also be installed on the original DSi provided it has CFW installed. Compatibility is high with only a few games having small loading lags, (i.e. GTA: Chinatown wars), or triggering anti-piracy protections (the latest version now includes AP patches for some games and will patch them on the fly). It also comes pre-bundled with a variety of emulators used on the DS and a work-in-progress GBA hypervisor, GBARunner2, that works to some degree.

DSiWare[edit]

Because the firmware that the 3DS uses for backwards-compatibility is actually the same as the DSi, it's possible to inject DSiWare as an installable .cia file. There's two ways to do this:

  • DSiWare Conversion Script - This script can be used to convert .bin files from your DSi's SD card to .nds which can then be used to convert into .cia.
  • GodMode9 - Version 1.8.0 added in a script that can convert .nds to .cia, 3ds.hacks.guide has more information on how to update to the latest version if needed.

These scripts will ONLY work for DSiWare, NOT NDS GAMES.

Others[edit]

CHIP-8[edit]

VC Injection[edit]

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.
There's an easy tool that will convert and inject any supported ROM file as it's associated VC application called New Super Ultimate Injector. It's an all in one tool and can even remotely install the injection provided your 3DS is connected to the same network. It's currently in beta, but it's still really useful.
