https://store.backbit.io/product/backbit-platinum-mvs/ I'm fairly tempted by this one, the inclusion of link ports really appeals and the cost is reasonable compared to picking up a couple duplicate linkable games.

Selling my single board JAMMA Demon Front IGS PGM. Has a bodge wire to address an input trace being damaged (just stopped working one day so I patched around it) and some slight pitting on the JAMMA connector underside. Everything works great, just not doing anything with it at this point (and I...

Over the years I've picked up a few superguns and JAMMA extensions that use similar but not identical PCBs and DB15 cables. Anyone know if these are interchangeable?

So, making another pass at repairing a consolized systems based off a MV1B with a supergun designed by NeoJamma. Last pass resulted in an unresolved short to ground. https://www.arcade-projects.com/threads/mv1b-5v-to-ground-short-and-stereo-mod-wire-running-from-opamp1-to-ic4.28884/ Piked up...

Anyone know the why behind this? Archives are in the way back machine from as recent as April 9th, but the site is no longer accessible.

So picked up a copy of Quiz Meitantei Neo & Geo - Quiz Daisousa Sen part 2. Everything looks original, but having a hard time finding this title on MVS scans etc. NGH-042 isn't even included in many Neo Geo master lists, most seemingly only showing the AES varrient. Anyone know why this is such...

Picked up a board that uses a CPU clip similar to a NeoBIOSMasta to add memory card support to a MV1B. It has a space for a BIOS, which I'd like to populate but I'm not sure which chip should work. Looks like a SOP44 and while I know they sell preflashed chips in that form factor for a 1C I'm...

I know these are poor monitors for actual use due to the latency, but I like the idea of having a small RGB screen for diagnostics. The issue I'm having is that while composite on inputs A and B work fine, S-Video on input A and RGBS on input C just give a "no sync" message. Not sure where to...

Can't find any documentation or service manuals, no idea how these work. But I have a dual slot main board, camera, wiring harness and some carts. How bad can it be? Printer may be an issue, but since it's a serial "remote" emulator for a medical s-video printer I'm thinking I can worry about...

This may be the wrong place for this, but it is MVS adjacent. As if I dont already have too many projects, I've decided to see if I can build a Neo Print system. Thinking of building one into a small hard-case that can be taken to conventions and what not. Tracked down most of the parts...

Looking for a cheap MV1B for a project, should be in my area to save on shipping. Would also take just the plastic housing, as I have enough spare parts to cobble one together but I lack a spare shell. Thanks,

Another broken MV1B on my workbench. This one with a third party NeoBIOS Masta that I think is the problem (lots of hot glue trying to hold it down @Neo-Alec here's an example of what I often see) but it also has a stereo mod with a detached wire. I've seen this before (example) but I have no...

Question for the class. Do the dual slot Neo Print main boards work with regular Neo Print carts or only the expansion carts?

Looking at taking another pass at rebuilding/fixing/tuning my Neo Geo cabinet monitor. Original issue was a blue tint (red driver). After recapping I was unable to tune it to the point where color balance was right. I'm thinking of getting a cheap third party chassis just to confirm that the...

Anyone know of a good guide to parts for making SOP 40/44 UniBIOS chips for MVS MV1B and MV1C boards? I've been just getting them from aliexpress, but thinking I should start making my own.

So I picked up a bootleg/clone MVS motherboard, because I'm weird and I always wanted one. I thought it was a "goldstar" model, but looking at it I can't find a match anywhere. Anyone have any information on this thing?

How are people storing their mini-marquee and other art? Feeling like "in a box" isn't the best option...

Trying to bring an AES back to life, symptom is a black screen regardless of cart etc. Running it through my Medusa, I see it struggling to figure out what the video signal is. Video shows the Medusa. Here is what it looks like with an identical but working AES system. Can't spot any...

I built out a MV1C system using a consolization kit I'd seen bouncing around on Tindie. It's not too bad, but has a couple short comings. The biggest for me is the lack of RGB adjustment potentiometers. On some of my scalers (RetroTink5x) the output image is very washed out. Since this kit...
