The mouSTer project – 20.11.2021 UPDATE


Another, long-awaited update on the mouSTer project 🙂

We are sorry that we’ve kept you without updates for so long time but this project eats up a lot of time and requires a lot of work.


Availability is not a problem nowadays. We have a stable manufacturing process and there should not be any hiccups in it. We are planning to make another batch soon.

Firmware updates

This is a major firmware update since the last one. It took tons of work and months too…

Willy/Lamers did a tremendous job with this one …

The whole code went through serious refactoring and we’ve finally added a long-awaited Amiga CD32 support along with other cool stuff like XBOX wireless dongle support.

The major problem was with CD32/A1200 RMB support/fix. We’ve received some feedback from current users that sometimes RMB doesn’t work on some Amiga 1200 machines – it worked on most of them though … or we didn’t get any decent feedback…

Since Willy was never into Amiga machines, he had to go through a bit dull learning process of learning its interiors to make it all work. Another KUDOS to him for doing this!

Unfortunately, It turned out again that if you want to make it a nice and working product … you have to go through the whole process yourself … and it takes AGES! so guys, please be patient as we also have real-life problems to sort out 🙂

PAULAs fault?

Researching this problem took ages and we’ve concluded that there are either minor differences in PAULA chips (responsible for mouse buttons) or PAULAs are broken in some machines due to time/wrong usage/accidents. There is also a possibility that some revisions of motherboards use different PAULA chips that are not so easy to work with. Another well-known problem is the infamous capacitor leaks very often found in A600s and A1200s that may cause issues.

If you guys know more about this, please let us know.

Below is a pic of Willy working place along with a bit of a “boosting aid” 😉

Anyway, we are hoping that through this update, the issue is fixed forever and if you have any info on it, it will help us a lot in making the mouSTer greater. Please drop us an email or simply comment here or on our Twitter or Facebook pages.

Willy also added a new cool feature that (hopefully) will sort out our problems with reporting all not working devices.

It is now super easy. If your USB device is not working (not supported), you just need to change a setting in an INI file “debug=true” and after plugging that non-working device you have to plug a USB flash drive where all needed info will be dumped and can be sent to us later on. This is still in an EXPERIMENTAL mode but we are hoping that it will speed up the whole support process.

3.16.2600 ->

  • Simple reporting after INI file processing was added. The new file “MOUSTER.MSG” is created with a short status.
  • Added FULL support for Amiga CD32 joypad. (default settings are for Sony DS4).
  • Added support for wireless XBOX 360 controller dongle.
  • Added Debug function, to improve feedback for unsupported devices.
  • Improved overall mouSTer stability (entering SOS mode)
  • Improved mouse latency. Worst case scenario – 20ms delay

There is also a GitHub page available now – work-in-progress – ->

Please, report all problems through the GitHub page from now on, as it simplifies the whole development process ->


For a brief moment, there was the wrong firmware uploaded to

If you’ve downloaded it and something is not working, please re-download it!!!

Future work

We are planning to work on an adapter to the mouSTer that will allow using it with retro PC or older Apple Macintosh machines. An adapter to an adapter (lol:) is needed in this case because RS232 does not supply enough juice to power up the mouSTer and is a kinda different beast to tame.

Anyway, in short, we would like the mouSTer to support Retro PCs (with RS232) and Apple Macs in the future.


This time we are proud to show you the link to a review by known in our small retro community STAR.

  1. I’ve been trying to use this with the ZX Next but I’m not getting any flashing LEDs; instead I get a solid light until I plug a USB key or Joypad in, then the light goes out and I just get a repeating ‘left’ signal to the joypad port. Won’t read firmware or ini files from USB. I hope it’s not dead.

  2. Hello,
    I received today my 2 mouSTer for the C64. I was planing to use one for Joystick and one for Mouse.
    1st I updated the Firmware and then tested one with the “Speedlink Competition Pro Joystick” but it didn’t work.
    Then I edited the ini File and set it to Mode 02 (for Joystick) but that didn’t help either.
    I tried the 2nd mouSTer but same thing. (the led is flashing 2 times fast then a pause.)
    I tried 2 Wirless Joysticks but also nothing (with the Wirless Dongle connected the mouSTer LED will constantly be on, not flashing but always on.)

    Then I edited the ini File of the 2nd mouSTer and changed it to Mouse mode and tested it on GEOS with a USB Mouse. The Mouse is working fine (just can’t move it very fast, but it work without a problem)

    Any Idea how to get the Joystick to work? With the Speedlink Competition Pro Joystick the mouSTEr led indicates that it has recognized the Joystick but nothing is work.

    The mouSTer with mouse mode is connected to Joystick Port 1 so that mouse will work in GEOS.
    The mouSTer with Joystick mode is connected to Joystick Port 2.

    I tried the otherway around but neither the mosue nor the Joystick works.

    1. Well, there is no easy way to do it and there is no software that supports it, at least we are not aware of it.

  3. Finally I can work with my Amiga 1200 and hide mechanical mice deep in the drawer – thanks to the right button issue addressed! Now: is there a chance to get mouse scroll working on the Amiga?
