Looking for some direction on a Ringedge 2 unit I purchased working with a multi from a member here quite awhile back. Because I have a bad habit of not testing stuff when it arrives, I finally got around to playing with this unit to find it isn't working. At first it was completely dead. Did some research to find out the coin battery could be the culprit, in which it was. So replaced that and everything fired up OK. However, on screen I get this blue screen I have attached a pic of. Looks to me that there is an issue with the SD, which I have attached a pic of that too. I looked around and found a link to a multi, Nikos I believe, and wrote the image to a new SD. When I replaced the original SD with the Niko one I found online, I get a black screen upon boot up with an ERROR 03. I am more concerned about the original setup not functioning, but I am a noob with Sega Ringedge hardware, so looking for direction on how to get this going properly. Any advice on what I could try, etc?
