smsPlus64

A Sega Master System and Game Gear Emulator running on the Nintendo 64. Use it on real hardware with an EverDrive-64. Tested with the EverDrive-64 X7 and SummerCart64 on both an NTSC and PAL Nintendo 64.

Note

This project is more of a fun thing for me to try if it works. It runs way too slow to be really usable and playable. I don't know if the emulator will ever run at full speed. Help is always welcome. Game Gear games run faster than Master System games and are much more playable. Try it yourself to find out.

Built with Libdragon

The emulator code is a port of smsPlus.

How to use on real hardware using an Everdrive 64 X7.

To try the emulator, download smsPlus64.z64 from the releases page en copy it to your flash card.

Games can be played from the flashcard's SD card. Create a folder named smsPlus64 in the root of your flashcard's SD card and copy your .sms or .gg ROMs there. You can organize your games in subfolders. The emulator shows a menu whith a list of games.

How to use on real hardware using N64Flashcartmenu on a flashcart.

For this to work with N64FlashCartMenu, copy smsPlus64.z64 to the menu/emulators folder of your SD-card. More info in the N64FlashcartMenu Getting Started Guide

Note

For the moment, you need to download the N64FlashcartMenu from the rolling pre-release, as the current release does not support this yet. Also, 1MB games will not load using this method. There are only a few games with this size.

Note

According to the Everdrive manual, roms could also be run this way via the Everdrive menu by saving smsPlus64.z64 as ED64/emu/gg.v64 and ED64/emu/sms.v64. This does not work however. As a workaround, you can rename your .sms .gg roms to have the .gen extension and then copy smsPlus64.z64 to ED64/emu/gen.v64

Controls

In menu

• D-pad Up or Down: Next previous game
• D-pad left or right: previous or next page.
• B: Go to previous folder
• A: Open folder or start selected game

In Game

• D-Pad: movement
• Start: Pause game
• B: Button 1
• A: Button 2
• Z + Start: Go back to menu
• Z + A: Toggle framerate
• Z + B: Toggle sound (improves framerate somewhat)

Note

Holding Z after starting the emulator will force to load the built-in menu.

Building from source

1. Install the Libdragon SDK. For more info and instructions, see https://github.com/DragonMinded/libdragon
2. Make sure the environment var N64_INST points to the installed SDK
3. Get the sources and build

git clone https://github.com/fhoedemakers/smsplus64.git
cd smsplus64
chmod +x build*.sh
./build.sh

Then copy smsPlus64.z64 to your flash drive.

Using an Emulator

You can also use an Emulator. Libdragon suggests Ares. This however requires building from source. Since an Everdrive is not used, copy your .gg or .sms files to the filesystem folder of this repoistory, then run build.sh. The roms will be baked into smsPlus64.z64

The files run64.sh, cp64.sh are used to run or copy smsPlus64.z64 to the Everdrive, using an USB cable. (using usb64.exe). Since usb64.exe runs on Windows, you need to build the project using WSL (Windows Subsystem for Linux) in order to use these scripts. If you are using Linux, you have to copy the file manually to the Everdrive.
