Hi. I photographed the damage on the board. Do you know what this contact affects/means, what is it for? Naomi still working. Most likely it appeared when I wanted to connect Naomi to the TV through a chinese adapter (vga to hdmi). There was a burning smell. I immediately turned off Naomi. Then I connected it back to the old TV and everything seems to work. but at that moment my sf card 1gb Sandisk stopped loading almost all naomi/aw games. it only runs dolphin blue and some naomi games. I don't know if this is a coincidence or not.

I think you need to get a new DIMM and maybe a new NAOMI. Looks like a lot of current has gone places where it should not.

That's what happens when you hook up to something that has a live chassis. This is the kind of damage seen when an arcade game board is hooked to a monitor in a cabinet that requires an isolation transormer, but doesn't have one installed. It feeds voltage back through the video cabe linto the PCB and does damage.

Where is the supercap located?

The mobo has a sticker stating "danger of explosion if the battery is replaced incorrectly". What can explode?
