You are a lifesaver! Checked the metadata and sure enough the path is incorrect. When I originally imported, I imported the zip files. But I recently unzipped all my roms. I corrected one to search for the unzipped rom and it worked! Thank you and appreciate the help!

Yes, I've downloaded the cores in RetroArch. I followed Retrogamecorp's starter guide. Only thing I can think of is to uninstall and reinstall RetroArch again. I don't think I'm doing anything else wrong.

I'm also having this same issue with my Odin where I try and load an nes game and I get a black screen. I'm using RetroArch (64-bit Sideloaded) and I have the correct core selected that has been downloaded from RetroArch site. I'm getting this issue with multiple systems (NES, SNES, ATARI) Only one that works is Genesis. Sometimes I will get a popup saying RetroArch isn't responding and asks to close app or wait. I've tested the games in RetroArch and they boot right up with the selected cores. Any help would be appreciated! Thank you!
