    CPS2 Digital AV interface is adding support for MV1C boards

    Another notable addition is that I adapted the brackets to work inside an Omega console. I created a mount for a keystone jack and rocker for the two UI buttons on the rear of the case.

    CPS2 Digital AV interface is adding support for MV1C boards

    Sorry for the late response, I didn't realize I was browsing NG without being signed in for a while. I can send you a QSB kit with a replacement rear panel for the OMVS for $50+shipping, or can do the install on my end for $125+shipping within the USA.

    A new consolized MVS has dropped, the "Open MVS" AKA "OMVS"

    Nothing wrong with options, just check your JNX audio channels, the two people in the TO discord realized that the left and right channels were swapped. Easy test is Alpha Mission 2, the stereo affect pans the shot sound effect left and right based on the ships position.

    MV1C background layer issue?

    Hey all, any idea what could possibly be wrong with this board? http://imgur.com/a/iqRTo4a The issue is really weird, as it one only seems to appear briefly after the high score screen loads on my KoF 97 cart. Cart works fine on my other boards, NeoDiag claims there are no hardware issues on...

    MV2-01 ZMC2 repair - no C-Rom sprites?

    I got a 2-slot board with heavy corrosion damage around the battery circuit: https://www.mvs-scans.com/images/5/5d/Mv2-01_set1_top.jpg At this point, I probed all the C-lines on the ZMC2 chip, restored all the connections between the C0 and the LSPC-A0, but I'm getting gameplay with sound and...

    Garbled music tracks in gameplay and jukebox?

    I have a problematic Twinkle Star Sprites boot that I've been trying to repair, everything in the cart works fine in gameplay, but the background music is constantly crackling and scratching. This is the only cart that I've experienced the problem with the music track, so I pulled both the M1...

    Watchdog when cart slots plugged in?

    Hi all, received a pretty clean 4-slot, but noticed that it was watchdogging on boot. I took the board apart, and saw that I get crosshatch when I boot it with the stock BIOS with the daughter board off, and get the service menu if I boot it using UniBios with the daughterboard off. I ran Neo...

    Bust A Move Again cart with corrupt pictures

    Hi all, I recently purchased a Bust A Move Again cart, cart has a Holo label and all the ICs on the board match mvs-scans. I booted up the carts and saw that the background layers and title logo have corrupted graphics. The sprites on the other hand look fine: https://imgur.com/a/c3WXG6N I...

    MV1 board won't power on

    Hi all, I sent a working MV1 board to a bud internationally, and he didn't test it originally after arrival. He removed the onboard battery, cleaned off dusty components with some IPA, let it dry, but upon attempting to power it in a confirmed working JAMMA cab/harness, the board does nothing...

    POLL: How do you store your MVS carts?

    I started using MVS cart protectors and lining the insides with shockbox art. Looks nice on the shelf, and doesnt take up too much space:

    Differences in PROG and CHA board types?

    Hi all, had a fun holiday season and decided to tear down all the spare/bootleg carts I've collected in the last few months, and ended up with the following: 1x PROG42G-1 1x PROGTOP 3x PROGBK1 1x CHA42G-1 4x CHA256 I decided that I'm going to try my hand at making a Ghostlop, Ironclad and...

    Neo Print 98 cart?

    Hi all, so I was planning on redo'ing a crappy label on one of my games, but upon peeling off the plain paper label that someone taped on, I realized that there was still an official seal and label underneath. I peeled it off as carefully as I could, and I could not seem to find a matching...

    Cart repair: Bad P1 ROM replacement?

    Hi all, recently picked up a Blazing Star cart with clean looking PCB that was claimed as 'for-parts' and after several hours of cleaning and testing with a known working Blazing Star cart, I determined that the P1 rom on the board is dead. The IC looks completely new, no signed of damage...

    Preferred 4-slot board variations?

    Hi all, completed my first significant repair for a MV4 board with corroded traces (batt acid) and dead ram, and I'm trying to decide if I should keep my MV4T or the newly repaired MV4? The MV4T works well enough with the exception that the sound on slots 1 and 2 are scratchy if the carts are...

    MVS>AES converter shells (Phantom-1, Fusion)

    Hi all, I modeled a shell for the Furrtek Fusion and the !Arcade! Phantom-1 if anyone is interested. The fusion one is dead simple, and maybe I'll revise it later, but I'm still hammering out the internals of my Phantom-1 case if anyone is interested in that (had to dremel and shave some...

    4-slot, messed up video (sync issue?)

    Just a MV4 board, no obvious signs of damaged traces or corrosion other than rust on the voltage regulator screw heads. No rust on the IC pins from what I saw at a glance. Already sprayed it down with contact cleaner and dusted it:

    4-slot, messed up video (sync issue?)

    Hi all, picked up another four slot for repairs, and this is the first board that I encountered where the video is completely distorted. The board appears to function for all four slots, but the video appears to have a sync issue. Colors work correctly from what I can make out, but the video...

    MVS -> AES converter? Phantom vs Fusion? (vs Daedalus)?

    Well, decided to test scaling on the converter with Last Blade, since it is easy to manipulate the scaling in Vs or Training mode. The Fusion doesn't handle it well :/ Fighters together (scaled in): Fighters apart (scaled out): Yuck. :(
