Sorry to piggy back the issue but I’m getting a similar one. I followed the Naomi tutorial and got a non merged set, did the bat files and did the 4 Naomi systems. But every game I load I get one error like”unable to find epr-23819a.ic22 in romset”, but i unzipped rom and it’s in the rom. Every game I click gives me a similar error but just a few different numbers? I tried downloading a different rom for testing and other bios, nothing has helped and ideas. I’m running demul 1111117.
