Nintendo - SNES / Famicom (bsnes Balanced)Link

BackgroundLink

bsnes is a Super Nintendo emulator that began development on 2004-10-14. It focuses on accuracy and clean code above all else. It never uses speed or compatibilty hacks. As a result, the minimum system requirements are greater than with other emulators. bsnes comes in three different profiles (accuracy, balanced and performance) which contain minor differences in the PPU (graphics) emulation.

This core has been compiled with the Balanced profile.

Highly accurate SNES emulation. Whether to use the Accuracy, or Balanced or Performance core depends on how much accuracy you want to give up for game performance.

Please check the compatibility section for more information.

Super GameBoyLink

Warning

Super GameBoy support in this core is Windows only, and has buggy save state support and visual glitches. Use the higan Accuracy core or the nSide Balanced core for simplified, functional, and easily accessible Super Gameboy support.

For Super GameBoy support, you need sgb.boot.rom (in RetroArch's System directory), a GameBoy ROM and a Super GameBoy ROM.

Please note that the Game Boy and Super GameBoy ROMs have to be unzipped.

Super GameBoy is supported via the Subsystem API.

There are two ways to access the Subsystem API.

One way is to access the Subsystem API through RetroArch's GUI like this.

First, we load our GameBoy ROM through 'Load Super GameBoy' in RetroArch's Main Menu.

Next, we load our Super GameBoy ROM through 'Load Super GameBoy' in RetroArch's Menu Menu.

Then, we start the content by selecting 'Start GameBoy' In RetroArch's Menu Menu.

The other way is to launch RetroArch with commandline like this.

1
retroarch -L {path to bsnes core} {path to Super GameBoy ROM} --subsystem sgb {path to GameBoy rom}

MSU-1Link

Attention

MSU-1 support in this core is complex. Use the Snes9x core for simplified and easily accessible MSU-1 support.

MSU-1 support can be used by loading a correct .bml file.

There's documentation for loading MSU-1 games in standalone higan here.
