I picked this up and have been trying my luck getting it dumped. Game is Amazon's Training Road for the NES by LimitedRunGames.
I know this is the header but I don't know how to make sure it's working, particularly making sure the mapper is correct.
"4E 45 53 1A 10 20 40 08 00 00 07 00 00 00 00 01"
Dumper is the MultiDumper_full_win_20230301 or Retro Dumper Client 2021.
