Emus for 3DS (VirtuaNES core) 0.91


Emus for 3DS (VirtuaNES core)


Emus for 3DS currently contains a single core VirtuaNES for 3DS, a high compatibility NES emulator for your old 3DS or 2DS. It's not as accurate as FCEUX or Nestopia, but it runs at full 60 FPS for almost all games, and supports tonnes of mappers: MMC1,3,5,6; VRC1,2,3,4,6,7; and tonnes of other mappers. As a result, the library of games it supports are huge.


This 3DS version also fixes a few bugs from VirtuaNES's MMC5 mappers and even plays Rockman 4 Minus Infinity and Zelda Legend of Link hacks.


It also runs on your New 3DS as well!


Homebrew Launcher:

  1. Copy virtuanes_3ds.3dsx, virtuanes_3ds.smdh and virtuanes_3ds_top.png into the /3ds/virtuanes_3ds folder on your SD card.
  2. Place your ROMs inside any folder.
  3. Go to your Homebrew Launcher (either via Cubic Ninja, Soundhax or other entry points) and launch the virtuanes_3ds emulator.


CIA Version:

  1. Use your favorite CIA installer to install virtuanes_3ds.cia into your CFW. You can also use FBI to download from TitleDB.
  2. Place your ROMs inside any folder.
  3. Copy virtuanes_3ds_top.png to ROOT of your SD card.
  4. Exit your CIA installer and go to your CFW's home screen to launch the app.



  1. To load .FDS games, make sure that you get the FDS BIOS.
  2. Rename the BIOS to disksys.rom and place it in /3ds/virtuanes_3ds/bios/disksys.rom

  2. Use Up/Down to choose option, and A to confirm. (Hold down X while pressing Up/Down to Page Up/Page Down)
