Hi, I've got a bit of an issue with my MV1-B.
The red warning sign appears after loading the rom from the neosd. It get stuck there and I can't do much but to do a reboot.
I am still able to enter the unibios menu or neosd menu.
I get a solid brown screen when an original MVS game is inserted.

What happened? I decided to do the stereo mod and make use of the 8-pin connector to route the audio. (initially meant for the track ball).
I did cut all traces under the 8-pin connector but pin 8 which is ground.

Obviously I triggered something nasty.

MV1-B
Unibios 4.0
NBM + VMC

Any help would be appreciated.

Go into testmode and then the hardware test and clear the backupRAM.

Thanks Raz, the issue was located somewhere else with the 8-pin connector.
Pin 7 connects to 2 points thru traces that I severed hence disabling the continuity. I linked back both point leaving pin 7 alone.
Everything works fine now :)
