The "Vs. System ROMs (Beta 0.10.0)" zip file uploaded yesterday had an error with the NES ROM, "from_below_vs_2021_01_13_v_0_10_0.nes". The EPROM bin files were fine; this was just an issue with the .nes file.
The file has been fix, and the zip has been re-uploaded.
If you load the NES file in an emulator and the colors look very wrong, you have the old file, and should download a new one.
Sorry about that!
