blargSNES is a Super NES emulator for the 3DS. With a homebrew-enabled 3DS, you can enjoy SNES games on the go.

Initallty made by StapleButter (aka Arisotura), and was updated by Shadowtrance for N3DS with sound supports.

Features

• PPU modes 0, 1, 2, 3, 4, 7, 8x8 and 16x16 tiles, sprites, windows.
• Hardware-accelerated renderer (about on par with the software renderer).
• Sound.
• Satisfying portion of the SNES hardware emulated.
• Support for headered (.smc) and headerless (.sfc) ROMs, LoROM and HiROM.
• SRAM with auto-saving.
• Joypad for player 1 (Circle Pad also works).
• Custom borders.
• Screen scaling.

Installation

The new build for N3DS is available in CIA, 3DS, and 3DSX formats (modified by Shadowtrance).

• CIA - Install the .cia with the CIA manager of your choice.
• 3DSX - Copy the blargSnes folder into the 3ds folder on your SD card.
• 3DS - Copy .3ds to your SD card.

To add ROMs, create a folder named snes on your SD card and put your SNES ROMs in there.

In the same folder, you can also place savegames. They must have the same name as their corresponding ROM, and have a .srm extension.

User guide

Start blargSnes and you will see a ROM selection menu.

See BlargSnes Compatibility List.

Configuration

Hardware renderer enables the hardware-accelerated renderer. It is faster than the software renderer but also less accurate in some cases.

Scaling provides some scaling modes for the video output.

Custom borders

To change the border picture on the top screen, place a 400x240px 24bit bitmaps picture named blargSnesBorder.bmp on the root of your 3DS SD card.

You can find some blargSNES custom borders and layout example from the official website.

Custom border submission thread at GBAtemp.

v1.3

• Usage of geometry shaders and other speedups to rendering.

v1.2

• Brand new hardware-accelerated renderer.
• Sound via CSND (not available to Gateway or Ninjhax on New 3DS).
• Scaling support.
• Exit button (mainly for use with the Homebrew Launcher).
• Emulation fixes (namely, huge 'next EXP' in Earthbound is fixed).
• Support for the 256x239 mode.
• Proper PAL support (actually uses PAL timings).
• Tries to prevent GPU freezes.

• Replaced forced 1/2 frameskip with automatic frameskipper (isn't perfect, though)
• More stable display (although tearing still occurs when frameskipping), VSync.
• More surprises.

v1.0
