[BUG]: Audio in Sanyo Pachinko Paradise 10 - Gen-san Okaeri! (Japan) is broken screeching

[drachenschanze]

Describe the Bug

As soon as you press a button on the memory card screen the sound effect gets much louder and stuck playing forever. I couldn't find a way to record audio in PCSX2 unfortunately or I'd post a recording. As soon as you get here move from the yes to no option.

Reproduction Steps

Start the game and interact with the memory card screen.

Sound work fine with +3 cyclerate. Even if bug is already triggered, setting +3 workaround it.

Seems like a game bug, but i'm not really good in SIF stuff. Game is disabling voice only if sceSifDmaStat return non negative value. I'm not familiar with that function but internally its testing SIF1 CHCR.STR, and return -1 if dma is not running. Problem starts when EE is too slow, and transfer already finished. Voice that should be disabled here is just still playing. More than that if you push any button, next dma is send without disabling old voices.

0x1181A4 jal          sceSifDmaStat
0x1181A8 move         $a0, $v0
0x1181AC bltz         $v0, skip_disable <-- Less than zero is returned if sif1 chcr str bit is 0
0x1181B0 addu         $v0, $s0, $s5
0x1181B4 sw           $zero, 4($v0)     <-- Disable voices send by that dma.

Patch to workaround it, not sure there is anything else that can fix it. Beside +3 cyclerate, or proper cycle counting. patch=1,EE,001181AC,word,00000000
