Need help with disable music codes, N64.

[Skaarjie]

Hello, Everyone.

I was wondering if anyone could offer some advice (or perhaps take it as a request and do it themselves)
on creating a code to disable or mute the BGM for some n64 games, namely: Snowboard kids 1 and Bomberman64

Doing many unknown data searches in SBK, I was able to find two addresses which correctly specified the music track playing. However changing either of them only worked in Menu's. the music in game was unchanged. I have seen single line codes for other games which mute all music in a game before. I'm aware it's most likey game specific and every game will handle BGM in completely different ways, but I guess if anyone had any experience or knowledge in finding an address which handles BGM volume, or an on/off switch I'd love to know.

of course, both games don't give any options for sound (except bomberman, offering a revolutionary Mono/Stereo setting.)

Cheers, Y'all!

Hi! Here's my first 1 cent post, I am into PSX and n64 is more of a unknown territory for me, nevertheless, I hope same or some logic can be applied in your case.

Try to listen carefully if music fade in or off is detected in some part of game, do greater/less search during that time and you should find it. Volume off is usually 0, as I have seen it. However if volume does not the change, you need to go after hacking bgm routines:

Chances are that in-menu and in-game music use same BGM start-stop routines you need to find out what code reads-writes on that BGM modifier to find out by careful observation the starting routine and just disabling it. Usually level loading includes setting the BGM music according level data and then starting the music. BTW, what does SBK mean?

That's really pointed me in the right direction. thanks!
I was successful with Bomberman64, the pause menu faded the music.
SBK is for Snowboard Kids, I had no luck with this one. I couldn't find anywhere the music faded, even between tracks its a rather sudden drop in volume, which could just be the sound chip stopping. either way, I had no luck searching that one.
I've never tried routine hacking, I'll give it a go after I get other stuff done, really not a lot of time to be N64 Hacking these days. :/


Anyway, in case anyone is interested.
