That fixed it :thumbup: . Music working and no more Z80 error. Many thanks

Yes i reflashed the flash.img, then the top file then the menu. All disappeared from the update folder so I assume worked ok. The AES version had a cpld file however and there wasn't one of those in the MVS fw.

I haven't updated my MVS multi in a while, but i've put on the latest fw and menu and now i'm not getting any sound. Also not getting any sound in the menu and if I go to select music it flashes up 'Z80 error'. However i've tested with a regular cart and sound is working fine with that. I...

No but I can try it, thanks @Darksoft

Sorry @Darksoft I only got around to trying it. I've updated the firmware and the top file (both disappeared from the update folder so assume all worked ok). Unfortunately there are still some pixel glitches on my 4-slot that are not present on my 1 or 2 slot.

@Darksoft Yes i'll give it ago :thumbup:

Yes I have done the trace cut in the cart. I have a 'NEO-MVH SLOT4' - the older model with all the 74 series logic on the top board.

What's the current status with multi slot boards? I'm still seeing random pixel issues with my 4 slot that don't show up on a 1 or 2 slot.

@Darksoft yes I updated the Fw and menu together, they both disappeared from the update folder. About menu says: FW rev. 0x0002 FW build 0x0003 Menu build date: Apr 1 2018 Menu build time 20:04:23 Have updated :)

Yes but @Darksoft suggested trying the mod anyway

@Darksoft i've done the power glitch mod (micro-sd slot still attached!) but it's had no effect on the glitches on my 4 -slot unfortunately.

Should be no problem, i'll give it a go and see if it helps.

@Darksoft i've tried it on my 1FZ and there are no issues with this mobo.

@Darksoft I can try on my 1-Slot later. I'll add i've not done the power glitch fix to my PCB, I assume this wasn't necessary for multi-slots

I've updated my cart with the latest Menu and FW and on my 4 slot there are still a few glitches although much improved on before. I tried Turfmasters, Magical Drop 3 and Metal Slug.

Woohoo look forward to this :)

To follow this up I fixed my MV -1FZ (bad BIOS socket!) and there are no pixel glitches with this mobo

They're moving, see... https://youtu.be/xNRSyT1fY2s Unfortunately I only have my 4 slot at the moment (that works anyway!)

Just tried this menu build (Dec 1, 2017) but the pixel glitches are still there unfortunately.

Updated ok and got the system working again, still have the corrupted pixels issue
