will removing the battery reset to default settings?

Yes, removing the battery restores everything to working state again, but it is frustrating that this seems to be the only way to fix this, and that it does not work as the manual says. And yes, I did try with two different boards (both are MV1C though), so I do not think the MVS board is the issue. Both had their rechargeable batteries replaced with CR2032's. It seems to me that instead of "returning to menu", what START + UP does is "reset the cart" so if it's configured to go straight to the games, it does that always.

I'd also like to remind about the strange issue with Garou always demo'ing the same fight, even with working CR2032 in place. Any idea about it?

Did u try pulling the battery and powering on without the cart?

He means try the cart without battery. I think the problem might be in your hack to replace the rechargable battery.

I used Xian Xi's guide to disable the charging circuit and replace the battery http://www.jamma-nation-x.com/jammax/tutorials.html and that seems to work fine, as the cart now saves settings correctly. Anyway, I don't get it...first, you say the cart does not work correctly because my board has no battery. I agree, the cart is designed for it, so I replaced the battery but the cart still does not seem to work correctly, and now you say to try it without a battery...I'm confused.

A bit more detail: when I press START + UP (3 seconds) the whole board seems to reset (I see the green background with changing colors which AFAIK are the BIOS initialization). If so, then it makes sense to me that with the cart configured to go straight into games, the menu is not shown. Is that right?

Couple more questions:
- What about the Garou issue i described above? any ideas?
- I also noticed that setting the cart's "Boot timer" to "NONE" in the menu, actually means "0": The menu appears, then the prisoner comes and displays 0, and then the first game is booted. Is that correct? I though NONE would be kind of "INFINITE" (manual does not explain this).
 
Man, we're doing what we can. No need to be so defensive. I don't remember all issues that every person has.

Now with the information that you said that it remembers settings well, I doubt it's a multi issue. My guess was that it's rather an issue with the hack that you made.

Try erasing the backup ram and deleting the buff file from the microSD.

It's also possible that for some reason it doesnt detect the START button after you called the menu. As soon as you press start+up and notice that the games wants to go to the menu,release the buttons and press start only.

Hopefully one of these would fix it.

The group issue, looks to me like there is no random anymore, like what happens when there is no battery. Let's see what happens when you try the other things I posted.
 
Good morning. I got my Darksoft MultiMvs. When I try playing on an Omega Mvs with NeoBios Masta and Neo Bios 4.0 the system just reboots and then get a green screen. I tried regular MVs carts and they play normal. Any help is appreciated.

Installing the NeoGeo BIOSMasta requires disabling the original BIOS chip - that's what the blue patch wire running across the OG BIOS chip is doing.

In order to use the original SNK BIOS, you'll want to re-attach the BIOSMasta and swap out the UniBIOS EPROM chip that's plugged into the socket on top of the Masta. I can send you a suitable EPROM with the stock BIOS if you need one.

Regarding the green screen you get with the Darksoft MVS cart with the UniBIOS, is the file system set up correctly on the SD card? Post a screenshot of the directory structure please.

The cart was working very good for 2 weeks. I even did the update, and was working well. I have read that it might be the Masta coming loose at some point and that I have to use hot glue to maintain its contact.
 
Ah, if the cart was working fine before then definitely check your BIOSMasta fit and make sure the cart contacts are clean. It’s rare but SD cards can fail too, so maybe try another SD card too if need be.

Hey started working again. Made sure the Masta was inserted firmly and added hot glue to the center and sides of it to make sure it would not move. The Darksoft cart loads perfectly again. Thank you once again. 🙏
 
Just got this - put it in my MVS 4-slot. SDHC card with a straight unzip of the Darksoft Neo Geo 2021-12-14.7z file. The screen shows 'checking games' but it gets stuck there.
I added the latest firmware and menu files in the update and update/menu folders - no difference. Any idea?
Thanks in advance!
 
hi, do you plan to release a new firmware in order to add Samurai Shodown 5 Perfect in the full romset? And is it planned a new menu update too? thank you
