Thanks team for checking on this issue. My leisure time has been in crunch!!. I did run the emulator and when it does not run the rom, I checked the /tmp/runcommand.log and honestly when I do “sudo edit” nothing is there.. I was surprised. I have changed 3 romsets because having corrupted romset was one of my thoughts. I don’t think I have the expertesie to rebuild romset. I will definitely check the romsize for neogeo.zip. Also it was a clean install and then I did the USB drive mapping. I do agree with dankcoushious regarding “doing too many thinks at the same time” but this time it was just a simple install.
What I noted that few FBA roms work and 90% don’t… I cant figure that out either.
