The Pi-MMS expansion cartridge is an easy way to add a Raspberry Pi to your MiSTer Multisystem, allowing you to enhance your retro game play on a number of MiSTer cores. This expansion is fully compatible/comparable with the MT32Pi for MiSTer.
This expansion cartridge slots into the MiSTer Multisystem with no additional power supplies or cables required.
Compatible with Multisystem1 and Multisystem2 Analogue - Not compatible with Multisystem2 Digital
A red version of the Pi-MMS cartridge is also available here
What you will receive:
- Pi-MMS PCB with OLED display
- 3D printed cartridge case in Charcoal Black
- All screws & buttons needed to operate the system
The PI-MMS expansion cartridge is assembled and ready to use (you need to provide and fit the Raspberry Pi Zero 2 / Zero 2W).
We recommend the Raspberry Pi Zero 2 without headers (not included) to use with the Pi-MMS. The board is compatible with other Pi products but the case is designed around the Pi Zero range. You will need to solder your Pi Zero to the Pi-MMS PCB to use the Pi-MMS.
The Pi’s Mini HDMI and USB ports are accessible on this cartridge, as is the SD card slot.

PI-MMS on MMS2
Got round to soldering this together today. Now plugged in and working lovely on the ao486 core. Gave me a big smile hearing Elite2 with lovely MT32 sound. I used a pi zero 2 w, I'm no expert at soldering, but this wasn't ok with a half decent iron (I used my £40 T12 Chinese iron with soldering station). Really nice to have MT32 sounds working in DOS and Windows 3.1 on the MMS2. Also have a Roland soundfont on the device, so can swap to that with a press of a button for games with general midi, like doom, and that sound pretty sweet too ? think I might try a bit of retro music production, with my lap desk, from the comfort of my armchair with the MMS2. Nice little project, especially if you like the 486 core ?

A must for any multi system
Great product and quality as always with heber. It’s well worth a purchase. I did encounter a trap for young players. When plugging in the mms pi cartridge it locked up my usb devices specifically my combined WiFi and Bluetooth dongle. I think this must triggered the poly fuses power protection. Anyway I’m happy to report that the multi system and mms pi work great when the combined WiFi and BT dongle is removed. It’s annoying not being able to use a Bluetooth controller but luckily my controller 2.4ghz dongle works just fine when the mms-pi is connected. I’ve also relocated my dongle to the back out side usb port so I can unplug it when I want to use my mms pi. Previously I had the dongle it connected to the internal usb port. I was thinking of sourcing separate WiFi and Bluetooth dongles to see if that helped. Here are some tips assembling your mms-pi You’ll want to be careful soldering the pi zero to mms pi board. Being careful not to damage the oled screen. I found putting a thin cardboard buffer and a heat proof mat cut to fit over the screen very helpful. Soldering wise the pin pitch is about 2.5mm. So not the worst but still care is need. Soldering isn’t difficult but doss require practice. If you aren’t very competent or out of practice it always makes sense to get some practice first. Just follow good practice of tinning the tip first. Then heat the pin you want to solder, introduce the solder, let it flow and then remove the iron after a few seconds to allow the solder to flow properly. Inspect the joint before moving on to the next. One good tip is use a good quality flux as well. Even if your solder has flux in it. I was always taught flux is an essential to making a good joint. One other thing to mention is a solder sucker is an essential just in case you accidentally bridge a joint. Then when your finished make sure you inspect your work before powering up. Time and patience is the key so don’t rush and you’ll be fine. Now all you need to do is prepare an SD card. Luckily the mt32-pj project now has a installer script you can use to provision an SD card. All you need to do is copy the script to your multi system. You’ll need an SD card reader to connect your sd card to your multi system as well. Other than that you’ll need to find the appropriate mt32 roms and optional sound fonts and you’ll have a working mt32-pi. Over all it’s a great addition to your multi system. Can’t wait to see what Richard and heber come up with next.
