So ultimately my cart wound up going to @Darksoft, and he determined that one of the SPI chips had died and was causing all the issues I had. I'm pleased to report that it's back in my possession and everything works great again.Still having problems, not sure what happened but I'd like to get this repaired if possible.
I would say that your SD card slot has gone south. I posted some information about how to change it. I could send you one if you feel comfortable chaning it. Just pay shipping. PM if interested.The one thing I noticed is the SD Card slot doesn't have any "eject spring" - you really need to grab it to pull it out of the socket. Not sure if this is normal or not.
5V Neo Geos (regardless of chipset type) do not have enough power to supply the multi due to a protection circuit it has on the input.Hello everyone, I use my multiAES on my neo geo 3.5. Everything works perfectly. I just bought a neo geo nec mothercard. I have the image but no sound. I use a quality 5A power supply though. I insert the cartridge + or - up but that doesn't change anything. I would like to point out that I have no problem with an original game. Do you know where this could come from?
THANKS
