A strange question about modifying cdda music

I recently modified a DC game, it is KOF98.
I want to modify one of the music of this game.

Perhaps a friend knows that in 3vs3 mode, after the first battle, the concert stops, and then after the second battle starts, the concert starts again.
I've found the address and modified it, and I've tested it on the simulator and the music won't stop (nulldc demul Makaron works all right)
But I found a strange problem in testing on gdemu. When testing on gdemu, it still stops and replays. It's a problem for me. Do any friends know what's going on?
Enclosed is the modified address:

Japanese version of GDI modified address 0x17a3fd00 0b43 change 0900
Japanese version of the 1st file is modified to address 0xBC26E 0b43 change 0900
US version of GDI modified address 0x181132c2 0b43 change 0900
US version of the 1st file modified address 0xBC2A2 0b43 change 0900

Can any friend help me try on gdemu?
thank you!

 

Well, this question looks stupid.

I guess it's because the way you read data and game CDs on the simulator is different. On a real host, there's a headless move to read other data, so the cdda track will definitely stop playing

 

Not sure if this is related, but playing Gunlord the music would stop playing once through the level until I pressed the Start button to pause it. Then it would continue to play. Been a while since I played from a disc so I can't remember if it does this normally as well?

 

I now conclude that the cdda game, when playing cd music, if you need to read data from other files, then the concert pauses or stops

 

yes

 

right. Demul works this way as well, perhaps you use some ancient version if it is not ?

 

yes， I use 0.582 demul

I changed the latest version of demul，There is also this problem.

The problem of hardware restriction can not be solved.

Thank you for your reply.
