I just got done finishing an MV-2F with lines in the graphics, so while it is still fresh I can post some stuff here for you to start checking, you can see my repair log here. https://www.neo-geo.com/forums/index.php?threads/help-for-mv-2f-with-bram-issue.272773/ I'm definitely no expert, but...

Just a heads up that I'm getting a Request Access notice for the video now. As for why it works but not in the shell, after confirming you have it in the boards assembled in the shell the right way (and remember the cart guide is not reversible), then I guess the first thing I would try would...

Works so well it plays as Metal Slug 3? Now I'm confused.

There are a few spots on the backside of the P-roms that I would be checking continuity on both ends of these spots. I can't tell exactly what's going on but looks like possible damage.

While not a great sign for how the cart was treated otherwise, the board makes connection with the contacts further up not down at that edge where the damage is. If this was the only damage I wouldn't really expect the game to not work before testing. Clean the contacts, try it and see what...

This guy saw a similar problem that was traced to a bad diode at D4. https://neo-geo.com/forums/index.php?threads/mv1c-problem-with-battery.260972/page-2#post-4243597

Bust-A-Move labeled (so US market) carts are in this shell. SamSho and Windjammers also except that they're clear. I'm sure there are others if you go looking. Thrash Rally was the last link cable game at the tail end of 1991, so possibly they just had a had a working mold and kept using it...

What brand is the RAM? Post here by James of JNX says the Sony RAM is usually good. https://www.neo-geo.com/forums/index.php?threads/mv1-a-mv1-fz-battery-mod.250241/#post-3997892 As for how long it lasts, I'm just about to wrap up a test on my MV-1A where it looks like it will have taken 12...

Have you seen this thread? https://neo-geo.com/forums/index.php?threads/mv1c-problem-with-battery.260972/post-4243568 I know most of the recommendations cover what you already did with C3, PC2, and PC4 but maybe there is something else that might help. I recently removed C3 from an MV-1A that...

You will want an MVS to JAMMA adapter such as the JNX Big Red. Your Big Red wiring and the 4 slot are not exactly JAMMA so to avoid any damage to the a JAMMA board, get an adapter. You will not be able to connect any of the following to an MV-1C, the Memory Card/Headphone board, EL panels, or...

Does that include an MV-1 specifically?

Has anyone run a Vortex cart on an MV-1? Or maybe rather, are there any known boards with compatibility issues and a Vortex cart? Seems to work fine on my MV-1A and MV-4 boards.

A couple small updates have been posted on the Backbit forum: On April 1st I've gone through 2 more PCB revisions, the latest which is going out to beta testers shortly. I've been spending a lot of time improving latency and stability. Case sample should arrive within about 2 weeks. If...

Sorry, it isn't for mapping the button layout. The MVS uses a slightly different wiring pinout on the JAMMA edge. The speakers are wired in series rather than in parallel and the adapter is to prevent damage to standard JAMMA audio amps. That's about the extent of what I know though, so...

I ordered a V2 from the latest batch as well as a Versus. Among other things, one goal I have is that I'd like to be able to use my two side by side 4 slot Neo Geo MVS cabs for some 4 player Konami beat em ups. So, trying to learn what I'll need to be setting up and doing when it arrives, in...
