Sound issues in Wonderboy 5

[Former user]

Original [issue 86](https://code.google.com/p/genplus-gx/issues/detail?id=86) created by talantyyr on 2010-05-22T13:14:50.000Z:

What steps will reproduce the problem? I don't know exactly when it occurs... I was playing Wonderboy in MonsterLand (best MegaDrive Game ever ^{) and after some time there was a slight "scratching" noise in the background. Music was playing normally but with this strange noise in background. (Sounds like bad radio reception) I reloaded the game (the whole rom) and sound was working fine again.}

Sorry that i don't know exactly when this happens, but maybe you can figure out what's happening?

Btw, i've also noticed a slight stuttering, but this happens very seldom... and only for <1sec, but it's noticeably.

I'm using the latest SVN Build (compiled 2 days ago) and haven't changed any settings in the emu

It's still in the beta stages, so issues like that are to be expected. But yeah, I can confirm this issue and hopefully will be resolved once the next official version is released (supposedly very soon).

Yep, just wanted to let ekeeke know. I'm working as quality engineering engineer, hence i'm used to point even obviously issues out =) But for a beta the overall quality is superior, besides some small issues like this one!

Thank for the input, i will have a look into it. Sound core us not in beta stage anymore, should be close toassaa perfection now so if you notice anyissue in games, please report it... Now about this one, try disabling low-pass filtering and see if that changes. If not, try playing withsound options.

Glad to hear that! Heck, you could say that if Kega Fusion was ever ported to the Wii and Gamecube, this would be it! Looking forward to the next version!

A question for eke-eke while this thread is up:

What settings would you personally recommend for best and loudest sound quality? I dunno if its just me and my stupidity but that HD FM thing seems to make it sound more quiet.

Hq fm does not change the output volume, it resamples the original chip samplerate to the wii native frequency, using a very accurate resampler. Rolloff adjusts the cutoff of the resampler so try to set it to max (0.999) for less frequency cutting. You can also adjust FM & PSG chips volume independently but the default setting should be the most accurate, i compared with a real mega drive hooked on the same tv and sound was not louder.

I'm having trouble reproducing this issue (everything is fine for me and I remember I already finished this game on this emu without noticing any sound issues). This does not seem to be related to the sound core emulation (the game does not make anything special) but might be a bug with the new sound mixing engine in some specific conditions.

Anyway, I'd need more infos about the configuration (ROM version, region setting, TV mode, audio settings, etc) and more details on where/when it happens (a savestate would be ery appreciated).

I didn't change any settings of genplus. (i don't know what this these sound settings do so i didn't want to touch them :)) The Sound glitches happend have happened only once yet, i've played 3 times since then and everything worked fine... I've also tried I also tried (wg. back then)to save state and restart genplus back then and the issues were gone... ROM Version, i'm not sure, i think it might be PAL Version but i'll have to check it to be sure. I guess it wouldn't be legal, if i attached the ROM here? I'm paying attention to the game sound but this happened only once. hä? Please do not waste to much time on this issue, i'll tell you if this happens again. (and hopefully i'll be able to discover when this happens).

@ nintendonerd1889: You said you can confirm this issue. Do you have this reproducable? Please tell ekeeke when this sound glitches appear at your wii

What I need to know is if you were running in 50Hz or 60hz. ->Video Settings-> TV Mode ->System Settings-> Region You can also load the ROM then open the ROM Information screen then tell me the last line (Region Code).

If you cannot reproduce the issue and it only happened once, it could be related to how long you played the game (without reloading state or entering the menu), maybe soundbuffer got squeezed after a while for an unknown reason, try returning where this happened to you and leave the game playing until it happens again. i'm not really convinced it is a serious issue though.

"@ nintendonerd1889: You said you can confirm this issue. Do you have this reproducible? Please tell ekeeke when this sound glitches appear at your wii" This issue doesn't necessarily happen in this particular game, but take any of the Sonic games; every once in a while, the jumping sound effect (among others) sounds as if it gets out of sync, making an odd squealing sound (maybe occurring every 45 seconds to one minute or so)It's as if the sound gets interrupted for one second or so. But then again, I was using an older beta revision and may have been fixed already.

@ nintendonerd1889: never noticed any of the issue you are describing, sound in Sonic is perfect in my ears

This kind of audio bug report can be a little frustating because :

(1) bug description is often very vague and bound to user appreciation (happen in every games ? when ? squealing sound ? interrupted or out of sync ?) (2) it is quite hard or impossible to reproduce it (sound skipping every 45s is a big issue imo, hard not to notice it) (3) audio sync issues should be non-existant now and the FM/PSG emulation should not have any remaining bugs (again, the GUI is in beta stage, the emulator itself is NOT)

Are you sure this is not a native game bug that occurs when repeating a particular sound effect (jump for example ?), this happens often with FM channels synthesis.

What I meant was it happened every 45 seconds; it doesn't last for 45 seconds. But, as you said, the issue is no longer noticeable, so that's good. Perhaps if I can find some luck, I'll compile from SVN and give it a whirl.

@ ekeeke: Yesterday i've play i played for more than 2 hours.. (wonderboy) There weren't any sound issues. I've tried to save/load state, and i've played more than a half hour without saving / loading. After playing i've also started a new game, and let shion stand around at the beginning of the game and let the wii turned turned on for about a hour.

My Settings: Video: PAL 60 Game: Wonderboy in Monster World - USA

I can't explain why this happened the first (and only) time... :( I also noticed the stuttering nintendonerd1889 mentioned, during this one time, but i also had this "bad radio reception" noise in the background too. Like he said, every 40 seconds the sound stumbled. But normally this doesn't happen normally, only this one time. I've also tried it with Sonic, but there were no issues either.

As soon as i find out WHEN this happens, i'll tell you immediatly.

(As already mentioned, i'm using the latest SVN build...)

Ok, let me know if this happen again. For teh time being, I'm closing this issue since nobody is able to reproduce it. I can always re-open it when we have more detailled report.
