SMSPlus emulates Sega's Master System and Game Gear systems. It was originally created by Charles MacDonald and ported to the Nintendo GameCube by The "Genesis Plus" Team.

SMSPlus has been converted from a PC based platform to run on the GameCube's proprietary PPC Gekko processor and features customized code to give you the best gaming experience possible. This port is based on SMSPlus 1.3 sourcecode but it's also featuring a lot of modifications & additions to improve games compatibility, emulation accuracy and various peripheral supports.

Features

• Accurate & full speed Sega Master System/Game Gear emulation:
  • NTSC (60Hz) & PAL (50Hz) timings support.
  • FM unit emulation (Japanese Master System).
  • Savestate support.
  • SMS BIOS support.
  • full Overscan area emulation (horizontal & vertical colored borders).
  • Blargg's NTSC filter support.
• Support for various input peripherals:
  • Sega 2-buttons Pad
  • Sega Light Phaser
  • Sega Paddle
  • 3D glasses faking
• GameCube/Wii extra features:
  • Stereo Sound (@48 kHz).
  • 1~2 Players support.
  • internal Game Database for automatic configuration.
  • SRAM and SaveState files (on Memory Card & SD Card).
  • automatic SRAM/Savestate loading & saving.
  • support for zipped (.zip) ROM files.
  • load ROM files from SDCard or DVD.
  • original video modes (240p/288p) support.
  • interlaced (576i/480i) & progressive (480p) video modes support.
  • Wiimote, Nunchuk & Classic Controller support.

Installation

Copy the apps directory to the root of your SD card to use SMSPlus with HBC or use the smsplus_wii.dol to load it with another loader.

Create the directory /smsplus/roms at the root of your SD Card and copy your ROM files (.zip, sms, .gg) there.

The ROMs can be placed on DVD-/+R (4.7GB max size) but you need to install the DVDx on your Wii. More info on that at HackMii. The DVD should use ISO 9660 file format.

Insert your SD Card into the Wii and run SMSPlus using your chosen method.

User guide

Main menu

• Load New Game - Load a ROM.
• Play Game - Begin playing the game.
• Hard reset - This should be like switching OFF/ON the POWER button on a real Master System. This will completely reinitialize the genesis virtual machine.
• Return to loader - This allow you to return to the loader used to launch the program, if any (Homebrew Channel, TP Loader, SDLOAD, PSOLOAD).
• System reboot - This will reboot your console (Gamecube Mode) or return to the Wii System Menu.

Load new game

Load Recent let you browse a ROM history list with the ten last opened ROM files. This is only available for ROM files previously loaded from SDCARD.

• Load from SD let you browse the SDCARD.
• Load from USB let you browse the USB Storage device (Wii only).
• Load from DVD let you browse the DVD.
• Stop DVD Motor will stop the DVD motor and the disc from spinning during playtime

Once you have selected an option, a file selection menu should appear. In this new selection menu, the following controls can be used:

• GameCube Controller.
• Wiimote (Horizontal).
• WIimote (Vertical) & Nunchuk.
• Classic Controller.

Savestate manager

Let you load/save SaveState data from/to the selected device: SaveState files is a feature that does not exist on real hardware and will let you save and restore your progress in ANY games, even those which don’t have internal saving feature. The SaveState data can be seen as a snapshot (or "freeze" state) of the current emulation state. Once restored, you will be able to continue your game at the exact point where you leaved it.

You can choose the device type. Be sure to set this according to your system configuration before saving/loading files.

Notes:

• You can configure the emulator so that it will automatically save SAVESTATE for the current game as soon as you load another game or quit the application. On the same way, SAVESTATE can automatically be restored after you load a game, if the files exist. This feature can be enabled/disabled via the System Options menu.
• When using NGC Memory Card in SLOTA, some mounting errors may occur. In this case, remove and insert the Memory Card again before trying to save/load anything or use SLOTB. Be sure to have also enough space on the Card before trying to save something (Freeze State and SRAM files are usually compressed).
• When using FAT device, the directory /smsplus/saves is automatically created. The default device is detected during initialization.

Display options

Aspect let you choose the Display Aspect Ratio:

• ORIGINAL - Automatically set the correct aspect ratio exactly as if you connected a real Master System on your TV. In this mode, the full resolution (720 x 480 or 720x574 pixels) is used to include horizontal and vertical borders around the active display area.
• STRETCH - Adjust horizontal and vertical scale values so that the active display fits your TV screen. When using this mode, borders are not emulated.

Render let you choose the Display Rendering mode:

• ORIGINAL - Use the original Master System rendering mode: this mode outputs a progressive 240 lines (288 lines for PAL) display.
• INTERLACED - Vertically scales (using hardware filtering features) the original display to a 480 lines (574 lines for PAL) interlaced display. In this mode, because of the higher resolution, games generally look better than on the real hardware but some artefacts might appear during intensive and fast action.
• PROGRESSIVE - Switch into Progressive Video Mode (480p), only use this with component cable and a compatible TV.

TV Mode let you choose the TV Mode to use:

• 50/60Hz - in this mode, the Gamecube automatically switch between the appropriates 50hz and 60Hz TV modes depending on the Master System current region mode. This makes PAL & NTSC games looking exactly like they did on a real console..
• 60Hz - in this mode, the Gamecube always use a 60Hz (NTSC or PAL60) TV mode, use this if your TV does not support 50Hz.
• 50Hz - in this mode, the Gamecube always use a 50Hz (PAL) TV mode, use this if your TV does not support 60Hz.

Bilinear Filter - Enable/disable hardware bilinear filtering. Emulation speed is not affected by this setting, however, when filtering is OFF, some graphic flickering might appear during screen scrolling.

NTSC Filter - Enable/disable Blargg’s NTSC filters. These are software filters that emulates the native artefacts produced by the NTSC Video Signal (color blending,…). Several predefined modes are available (COMPOSITE, S-VIDEO & RGB) which simulates the associated video signal.

Borders - Enable/disable the border colour emulation: when ON, the background colour is used (like on a real console). When OFF, borders are forced to black. When ASPECT mode is set to STRETCH, this option is automatically set to OFF. On the other way, enabling this option automatically set ASPECT mode to ORIGINAL.

Center X/Center Y - Adjust the screen position while keeping the display aspect ratio.

Scale X/Scale Y - Adjust the display aspect ratio. This option is only accessible when using STRETCH aspect mode.

System options

FM Type - Disable FM emulation (OFF) or choose between two FM emulators (YM2413,EMU2413). Please not that only some Japanese games feature FM music so enabling this will force the system into japanese mode.

Country - Force the region of the game. Let this to AUTO if you want the program to pick automatically the best setting for each game. Some games may be region protected.

Console - Force the type of console to be emulated (Master System 1, 2 or Japanese (MARK III), Gamegear...), Let this to AUTO if you want the program to pick automatically the best setting for each game.

Sprite Limit - Enable/disable emulation of original hardware limitation that can produce sprite flickering in some games. Disabling this option will reduce Sprite Flickering and improve display rendering.

Use BIOS - Enable/disable SMS BIOS support. If you want to use this feature (this is not required to play games), the BIOS rom (not provided) must be renamed as "BIOS.sms" and placed in the /smsplus/ directory, on the default FAT device.

Extra GG - Enable/disable the hidden display area, normally hidden by the original Game Gear LCD screen edges.

FREEZE Auto - Enable/disable automatic SaveState loading when a new game has been loaded and autosaving when you quit the emulator or load a new game. This option let you specify the location for the SaveState files:

• FAT (SD or USB for Wii, default device is detected upon startup).
• MEMCARD (slot A or slot B).

Controls options
