What is Emulator?

"Snes9x is a portable, freeware Super Nintendo Entertainment System (SNES) emulator. It basically allows you to play most games designed for the SNES and Super Famicom Nintendo game systems on your PC or Workstation; which includes some real gems that were only ever released in Japan.

Snes9x is the result of well over three years worth of part-time hacking, coding, recoding, debugging, divorce, etc. (just kidding about the divorce bit). Snes9x is coded in C++, with three assembler CPU emulation cores on the i386 Linux and Windows ports.

Currently there are many ports of Snes9x available" (SOURCE:http://www.Snes9x.com/)

How do I set it up?

This is a standalone emulator with a GUI just download and execute. The key to screen rotation is matching display resolution with the output of the emulator. The default for this emulator a menu is visible at startup. In a normal situation the escape key would hide this menu but most Mame™ machines employ the escape key to end the current emulation. This can be overcome with the use of a wrapper. With the use of a Wrapper Snes9x is a very stable seamless emulator for arcade machines.

NOTE: In version 1.51 a cfg setting was added to auto-hide the menu on start up a wrapper is still necessary in order to route the esc key to end the emulator.

Command Line Parameters

Snes9x can be executed via the command line as follows:

Brief:

"C:\Snes9x Folder\Snes9x.exe" "D:\Some Folder\Your Roms\Romfile.smc" <<With quotations

If you have the Snes9x pointed to a specific ROM directory <<Default "./roms":

"C:\Snes9x Folder\Snes9x.exe" "Romfile.smc"

Snes9x supports compressed ROMs in zip, gzip and JMA format as follows:

"C:\Snes9x Folder\Snes9x.exe" "D:\Some Folder\Your Roms\Romfile.zip"
                   OR
"C:\Snes9x Folder\Snes9x.exe" "Romfile.zip"

ROM image needs to be in Super MagiCom (*.smc), Super FamiCom (*.sfc),

Display Orientation

The key to the rotation of Snes9x emulation is screen resolution.

Normal horizontal desktop resolution:

“800 x 600” or “Larger Value x Smaller Value”

Vertical Desktop resolution:

“600 x 800” or “Smaller Value x Larger Value”

Snes9x Does not have a setting to rotate the display so you must specify a vertical resolution in the video settings of the emulator. This resolution must match the resolution of your desktop and your desktop must be rotated. You can specify Snes9x to stretch to fit the given resolution, the distortion is unnoticeable. The vertical display modes can be set manually via the .cfg if you are using snes9x v1.51,. Else the display modes do not appear in the video setting of Snes9x until your desktop display is at a vertical resolution.

NOTE: Many emulators do not support rotated display to overcome this specify a vertical resolution in the video settings of said emulator.
