Switch/Panic! sound effect problem

[Former user]

Original [issue 241](https://code.google.com/p/genplus-gx/issues/detail?id=241) created by superballena on 2012-07-06T16:53:54.000Z:

What steps will reproduce the problem? 1. Load the game

What is the expected output? What do you see instead? Every sound effect after GASE will be partially played, and keep a bit of it looping after the next sound effect is played.

Also, occasional crashes.

What version of the emulator are you using (official, SVN revision,...)? 1.7.0, default settings

Please provide any additional information below (Emulator settings, Console setting,...) Japan BIOS 1.00, ISO+WAV US BIOS 1.10, BIN+CUE US BIOS 2.00, BIN+CUE

It seems that the looping bit that keeps repeating belongs to the previous sound effect that had been played.

What is the GAZE ?

And what do you mean by occasional crash ? PCM emulation bugs i can fix, random crash is more problematic as it can't be investigated without more details on how to reproduce it consistently or detailled description of the context.

"GASE" instead of "SEGA", the very first sound that plays in the game, and the only one that doesn't act strange.

Well, I thought the crashes were random but it turns out that the Japanese version just hangs up at different places. You can make it crash (or rather, make it wait forever) easily by just starting a game and selecting the top left onscreen button. Then, press any of the two elevator buttons and nothing will ever happen again.

Also, once you're inside the elevator in the US version (pressing the "Up" button to call it), the kid's graphics will show some garbled tiles while the cabin shrinks (pressing the "Telephone" button, at the bottom)...

In any case, these could be related to the game trying to synchronize with the audio clips, so they might just vanished once that's taken care of.

Just found out how to reproduce the hang up in the US version. Just start a game and press these in-game buttons:

-"Top left" -"Up" -"1" -Any button and that's it

Here's the savestates for both versions. Just press any button in those scenes and the game will just stay there.

Hum, again it seems the game is locked reading an invalid track, so I guess the lock is due to invalid TOC returned by emulated CDD. Check if it works better with the test dol posted in Sonic CD issue report (DO NOT load these savestates as they are screwed by the previous bad TOC).

I have not tried to reproduce the original sound effect issues yet, which is a different issue anyway. It seems like Final Fight CD has missing sound effects as well, which indicates some bug in Sega CD PCM emulation

Was indeed an issue with PCM emulation, should be fixed now
