Kikikai-kai: Dotou Hen (known as Pocky & Rocky) for the FDS doesn't work correctly on any emulator, except the old NNNesterJ.
The only no-intro dump is labeled as (b), which means it's probably a bad dump. The GoodFDS version has no label. So, I don't know if this hang is a result of the game being a bad dump for the past 15 years, of if it's just not emulated correctly on any emulator.
This game has been reported as broken on pretty much every emulator github page, and it has never been fixed. Hopefully one of you guys can finally fix it for Bizhawk.
If you want to get to the part in question, just follow these steps:
From the start point, walk straight up. Don't attack with your cards because you need all 50 of them. Keep following the path north until you get the first chance to travel east (you'll cross a few bridges just before that point.) Head east as soon as you are able, and then take the very next path south. This will lead you to the entrance of a cave. You need 50 cards to enter the cave (you can earn Ofuda cards by defeating enemies with your wand). Once inside, the path to the boss never branches. You travel north, then east, and the north. At the top of the second north path is the boss room. The expected result (and the one which NNNesterJ produces) is that the room scrolls into view, turns blue, and a large boss starts to attack you. The actual result in the rest of the emulators I've tried is that they hang before the room turns blue, stuck playing one note.
Or just can use this save state. Just walk up and the game will hang.
