Picked up another MV1B, thought it was working fine however noticed some games didn't have audio, but some did and then with some experimentation found some games had slightly broken audio. For example, Xeno Crisis seemed to have all sounds, whereas not a peep out of Metal Slug and Garou was...

My MV1B has developed a Backup RAM unwriteable fault, it seemed to start after I cleared the Backup RAM and now it triggers on every boot. Popped the diag BIOS in and I get this: I assumed RAM4 is the upper chip and as I had a spare replacement TC55257DFL-85L chip from when I fixed the...

I have four Neo Geo Fusion converters available, after I made one for myself. The PCBs were fabbed with ENIG finish, Gold fingers, bevelled edge, etc. so they're the best quality and each one has been tested in my AES and confirmed to work with a handful of MVS cartridges. £50 each, plus...

For consideration is my Neo Geo 25" cabinet (MVS-U4) with blue stools. The cabinet is in really nice condition, but I currently have an Arcooda 21 inch LED in it. I bought this machine less than a year ago and the chassis seems to have been damaged during transport, so I put in an LED with the...

I‘m looking for a Darksoft NEO GEO Multi-MVS cartridge. I would prefere to get it from somewhere in Europe.

Got a cage that someone have tried to paint white. I'm looking for the cage stickers for this system. I was surprised I couldn't find it. A scan of the cage would be a dream to work with :) I have circled the stickers I'm looking for. Picture is not showing my board. Please help :)

我非常确定它们都是正品，我可以拍摄PCB板的特写照片。

I have an mv1c that used to drain a full battery In about 30 minutes. I installed a ml2032 and universe bios to no effect. Removing capacitors c3, pc2 and pc4 from the board slowed the drain to about 24 hours. This is not a major issue and I understand that this can happen to the mv1b and mv1c...

I just got my hands on a Big Red cabinet and want to start playing it ASAP. The only problem is that the four slot needs some work such a recapping, leaked capacitor cleanup and a serious deep cleaning. The downside is I got a bunch of projects that take precedence over this. Luckily for me...

My MV1B has one of the NEO-BUF bypass "patches" on the slot PCB, (the one on the main PCB is still present). According to https://wiki.neogeodev.org/index.php?title=NEO-BUF bypassing one/both of these, (it doesn't state which and sort of implies there's only one, when there's actually two), can...

I recently built some of @ack's excellent Neo Geo diagnostic PCBs just as a useful thing to keep handy. Testing them out on my MV1B I wasn't expecting to have any issues. However the first time I tried them with the latest v0.19a02 diagnostic BIOS, I got a VRAM 32K error on power up which I...

Having a clear out and found some extra units of things I assembled: SOLD Neo Geo AES Memory Card (£30): This is Furrtek's design using FRAM so no need for a battery. Two selectable banks. One unit remaining, not sure if they can be made now as the PCMCIA connectors seem to be EOL everywhere...

Hey folks! I'm hoping one or more of you out there might be familiar with the NeoBiosMasta mod; or, more broadly, unibios installation on an MV-1C board. I'm attempting to give it a go here, and I'm afraid I've run into a bit of a wall. I'll start at the beginning: I utilized a heat gun to...

Hi there, I got a Shock Troopers 2 with P1 mask rom dead, its blown in the middle of eprom. I don't had one 27c160 to change it so I tried with an 27c322. The process was this: P1 have 1MB 27c322 is a 4MB eprom so I got the rom and copied p1, doubled it to 2MB and doubled to 4MB, when I teste...

I have been putting of this project and prolonging it for quite some time, trying to find an excuse to stay away. But I have decided that it is time. When I first started working on the cab, I had power issues (not enough power to run the main motherboard). The screen would turn on, but it...
