Gameshark Japanese Game Problem

Hi,

I've bought a GameShark a couple of months ago on Ebay. It's working fine and I'm having a lot of fun with it. But the main point of buying it was to play Japanese games without having to buy a japanese console + electricity adapter or without opening my N64 to remove the region-lock pins.

It took me some time to figure out how to launch the game, but now it does! I can play Banjo-Kazooie japanese version! (My parents only bought me Banjo-Tooie as a kid and the japanese version of the Kazooie one was SO MUCH cheaper!)

Everything started quite weird when I started a game. I could see the cutscenes and even walk around Spiral Mountain, learn the moves and gather some honeycomb thing to increase my total life. But when I decided to head to Gruntilda's Lair and start the game for real, the bridge was broker. I read that if you do not know all the basic moves, you can't proceed with the game. But I've learned them all! I even started another game and told Bottle that I don't need him to teach me the moves (unlocking them at the end of the first dialogue) but still, the bridge was broken. I tried some trick with Gruntilda's chin to enter but nothing worked.

I noticed something later on, when I start the game, the bridge is just fine. So I managed to climb on top on Spiral Mountain without losing the bridge from my camera and it was just fine! I could start my game!

I know it's quite a long intro but it's just to show you how broken the game can be. When I entered Gruntilda's Lair, I thought that all would be just fine. I got in the first level and could get all the Jiggies and the Notes. But when it was time for me to leave, the exit pad was not working. I was stepping on it, pressing every button on my controller but nothing worked. I can simply Save and Quit my game, reenter it and go on to the next level, but the point is that I can't get one of the Jiggies. I'm talking about the one on top of the first world's entrance, the one you must be an ant to get. But I can't leave a level with the pad, so can't be an ant in the overworld!

I know that memory is not used the same way in the american and japanese games, that's maybe the reason why the game was considering that I didn't had all the moves, because it changes a wrong value in the memory to tell that I've learned a move.

If you have any clue how to fix this or any code I could use to fix some issues, let me know please! I looking forward completing the game with a 100%, but this Jiggies bugs me. And I want to prevent further bugs to happen as well.

Thank you!

 

I assume you are using a NTSC N64.
You could just take the back of an American game, and swap it with the Japanese one.
That way you could be certain that it isn't the Gameshark which is the troublemaker.
