Seta GX is an experimental Sega Saturn emulator by fadedled (also known as Evoca) based on Yabause Wii, but includes improvements taken from devmiyax's Yaba Sanshiro, such as CHD support and SCU emulation.

Features

Supports CUE and CHD formats (the latter with a slight performance penalty, about 5% slower). It also supports bin+cue and bin+img combinations (especially for beta or prototype games).
Supports GameCube Controller, Wiimote and Classic Controller.
Support for SD and USB devices with FAT32 filesystem.
Significant improvements over Yabause Wii, thanks to hardware acceleration via Hollywood GPU tricks.
Some games hit 60-99% of native speed (e.g. Clockwork Knight 1 and 2, Powerslave with 70-90% FPS), while others, such as prototypes, can drop to 20-50 FPS with missing textures or graphical glitches.

Installation

Download the latest version.

Extract the archive and copy the apps/SetaGX folder into the apps folder to your USB/SD card root.

Create folders vgames/Saturn for games and saves/Saturn for saves.

You must also provide your own copy a Sega Saturn BIOS file (bios.bin) and place it in apps/SetaGX/.

User guide

Using a Homebrew Channel on a modded Wii to launch Silk GX. Navigate the menu with a GameCube Controller (or Wiimote/Classic Controller from v0.3.1).

To return to the menu press Start + Z on GameCube Controller and Home on Wii controllers, this will close the game so save before doing this.

In the menu you can select a game and press A/2 to start it (if you start a game while holding R a FPS counter will show), pressing B/1 will return to the Homebrew Channel.

+Download the latest version.
-* Optimized opcode decoding for the Saturn SH2 CPU.
+Extract the archive and copy the <code>apps/SetaGX</code> folder into the apps folder to your USB/SD card root.
-* Integration of Musashi m68k plugin to improve Motorola 68000 processor emulation.
-* Removed audio plugin to reduce complexity.
-* Fixed memory leaks and simplified device loading.
-== Usage ==
+Create folders <code>vgames/Saturn</code> for games and <code>saves/Saturn</code> for saves.
-=== Installation ===
-* Download the latest version.
+You must also provide your own copy a Sega Saturn BIOS file (<code>bios.bin</code>) and place it in <code>apps/SetaGX/</code>.
