What power supply is being used? A lot of CMVS units use not great power bricks that may not be providing enough current - or the regulator isn’t keeping it at close enough to 5v I would assume the multi cart will be more sensitive to bad power than an original cart since it is bringing down...

I’ll check but I think I used all the spares I had How many do you need?

Without a working A and B set there is no way to tell for sure. But given the damage to your B board that would be the starting point

If you have another B board you can use for the multi that would be the way to go. That board needs to be sent to someone who can check it over and repair it The battery damage isn’t bad and I think it will be salvageable. Looking at it briefly - D1 is missing - D5 is corroded and very...

I think it will snap into the plastic ring, you don’t want to use glue because that will modify the weight/balance of the spindle At least if you buy from the Aliexpress seller you get 5 attempts at making it work

I was thinking you could just remove the metal ring that he needs from the PS1 spindle and put it on the Sega CD spindle instead

You can get them for a PS1 and they should still fit. Not sure if you’re affected by the tariffs yet but these still shouldn’t be too bad https://a.aliexpress.com/_mPlaT0R

Revision 1.1 is unfortunately not working having received and built the PCBs - please ignore this build for now, I will also remove it from the Github

New USB revision released - v1.1 - Updated resistor sizes for switch and button header - Added decoupling capacitor to 5V - Added resistors for LEDs to allow for smaller LEDs to be used - Realigned USB ports - Realigned screw holes Updated Gerbers available on Github now, BOM has not yet been...

The latest revision v1.01 boards arrived today and I put one together ready to install in its new home in my 4 slot cab I reworked the code to use only the bottom 4 connections and had some fun with the test LED colours Next step: installing in the cab

I have recently been working on a project and have got to a stage where I can release it https://www.arcade-projects.com/threads/released-open-source-neo-geo-mvs-marquee-driver.33135/ For those of you who have LAI MVS lowboys or MV4-U29 cabs without the backlit mini marquees this is for you I...

This is now released! PCB design files and Gerbers can be downloaded from GitHub - all functions except manual switching have been tested (waiting on boards with the switch to be able to test that functionality and will confirm once done)

Several people have requested the ability to run a panel in a cab where there may only be a single slot board due to failure of the 2/4/6 slot board. I have added 2 options for this Attract Mode Marquees will cycle through automatically on a 1 second delay Manual Mode Marquees can be changed...

The boards for the latest prototype revision arrived today - I am hoping this will be the final test version before production. This is the USB version designed for use with EL panels commonly found on Aliexpress All parts on the board are through hole and very easily available from Digikey and...

Yeah it’s not a bootleg where they use compatible parts to reproduce custom hardware like a traditional bootleg From what I’ve seen the PCBs on the reproductions are very well made and at least on par with original too
