Hi Darksoft,
I have a matter with my multi mvs.
During several month, games worked very well but one day music sound of menu + all game became unpleasant.
Of course, I tried to change with other SD card but problem persists and now I have always message "CROSS HATCH TEST" when I want to play it.
I played with slot MV1FZS and I try with MV2F.
Also I tried with ATX + arcade supply.
I tasted each slot with unibios 3.3 + 4.0 and without unibios and the matter is always running.
I tried to change firmware by latest version without success.
I own original MVS and all of them work perfectly.
Now I suppose that matter is coming from SD slot but I do not have the skill to do it by myself.
Is it possible to send you the multi MVS in order to diagnostic it?
Thank a lot for all your attention.
