I checked Bizhawk (not the latest version), FCEUX, NesterJ, Nestopia, VirtuaNES, Messen and none emulate Tsuri Kichi Sanpei: Blue Marlin Hen correctly. It's easy to replicate. Just start the game, press start to open the map, sail to the docks on the right (a square will light on), then press start and you'll see this: But you should really see this:

Pretty clearly a mapper issue, but I can't find any information about which one it should be. I'll look into it.

When you open the ROM you have for this game in NESHawk with the log window open, what does it show? I got a copy and opened it up and the pcb says it's hvc-unrom--03. I dumped it with 128k PRG ROm and 0 CHR ORM and it runs just fine. (this is pretty standard.) EDIT: Also the hash i get matches that on no-intro.

I've found a dump that works fine. However, it's marked as pirated [p1]. 
    File: Tsuri Kichi Sanpei - Blue Marlin Hen (J) [p1].nes
  CRC-32: 92636a0d

With any else dump, it behaves like what ReyVGM showed. Note that the only good dump is this one:

my personal page - my YouTube channel - my GitHub - my Discord: thunderaxe31 <Masterjun> if you look at the "NES" in a weird angle, it actually clearly says "GBA"

Seems to be just bad nametable mirroring in the header (the black box appears when it's backwards from what it should be.) I committed a fix. whatever the header says, the prg rom should have this hash:
