As the title suggests, there's a screen mirroring problem in Karnov. I checked the header of my dumped cartridge I made with CopyNES Mini, and everything looks correct in various emulators. However, on the JB firmware, this game looks like it is incorrectly set to vertical mirroring instead of horizontal.
Also, a few hacks I have either aren't loading up at all (Strange SMB, SMB Special 35th Anniversary), or are loading up incorrectly (Super PItfall Anniversary). The affected hacks run correctly on an emulator.
