This one is tricky, I guess it is missing because it contains 2 files. Both are required for the game to run (as the .sav file is being used as an additional ROM bank).

Definitely a tricky one. Do you know how RetroArch responds to this? Since RA indexes the .nes files, and loads just that into the emulator, I'm sure this is not working at all.

I don't know much about how RetroArch processes its ROM scanning, but I just tested with RA 1.9.12 (Win x64 stable) and suprisingly this game is correctly detected with a directory scan or manual scan (only the .nes file is in the playlist).

It's not playable though, the emulation starts but is stuck on a blank screen (I tried the 4 NES cores), but I guess that's a core issue rather than a database issue? Or is the database supposed to "tell" RA cores "for this ROM use this extra file" somehow?
