Hello, I've got a MV1FZ with an Z80 error. When I insert the Diagnostic BIOS (v0.19.a02) it says "all tests passed" and when I use an additional diagnostic cart it says "SM1/Z80 prepare slot switch ignored" (see photo). Pressing Start does nothing. The Z80 seems to be already replaced by the...

"homebrw1" is correct. You'll need the newest menu (see 1st post). Deleting the BUFF file from the sd card and clearing the backup RAM will also help. ;)

Thanks for your detailed answer to my question. No I can clearly understand why there is no screen rotation mode, yet. I'm really looking forward to test and play your future ports. :thumbup:

Yes, this was buzzing #1. Buzzing #2 was fixed (at least for me) by changing the fpga file value to 101. :) Thank you very much for your effort bringing the game to Neo Geo! :thumbup: :thumbup::thumbup: ... any chance a button combo or else for screen rotation mode could be implemented?:saint:

GFX are ok, sound is ok ok with fpga set to 101. But I've found another issue: When the free play DIP switch is activated, the credit counter rapidly counts up (like 'autofire' :huh: ) and there is a constant buzzing/humming (also during game play). Without free play activated everything seems...

I've tested it with the MVS multi via "HOMEBW1" slot on a MV-1FZ(S) and there is massive buzzing instead of audio...

To my knowledge there is no MVS port of the game.

:thumbup:

Maybe deleting the BUFF file and/or clearing the Backup RAM will help?

Maybe @pacoarcade can help you out? https://www.arcade-projects.com/threads/picogun-video-buffer.13775/

@Darksoft I've tested it for about 10 minutes and it seems to work. :)

Hi, would it be possible to integrate the new Rally Chase CD to Cartridge Conversion? https://www.neo-geo.com/forums/index.php?threads/rally-chase-cd-to-cartridge-conversion.269509/ :)

Don't know - the project status seems to be from 2018: https://pcbjunkie.net/index.php/2018/04/20/jamma-test-card-and-project-updates/

You can find the gerber files etc. in the 1st post. ;)

sorry, wasn't clear to me :)

It's a known bug of the UNIBIOS 4: "On Multislot hardware sound is missing if no game in SLOT 1 (bug introduced in v4)." see http://unibios.free.fr/knownissues.html

Today I've tested the Miniun Supergun (v2.5 miniDIN9-Version) of a friend of mine with my LCD TV. I've used an unmodified Neo Geo MV1-FZ. With a direct connection between MVS, Supergun and TV (via SCART) I get a picture but with the OSSC interconnected I get no picuture and the OSSC says "no...

No it doesn't but only the 1st one is available :)
