How to use

 

You need a way to run ARM11 userland homebrew on your 3DS. At the time of writing this, the simplest way is to use a Gateway.

 

If using a Gateway, copy blargSnes.3ds to the Gateway's MicroSD. Otherwise, follow the instructions specific to your homebrew loader.

 

You're on your own for getting SNES ROMs.

 

On the 3DS's SD card (not the Gateway MicroSD), create a folder named 'snes' 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.
With that done, start blargSnes, and you see a ROM selection menu. Select your ROM and press A (or B). See what happens.

 

You can pause gameplay by tapping the touchscreen. When paused, resume by pressing A or B.

 

DO NOT RETURN TO THE HOME MENU WITHOUT HAVING PAUSED FIRST.

 

Also avoid playing with the 3D slider or closing/reopening your 3DS while blargSnes is running.
