GameBoy, bad sound emulation #803

Closed SieKensou closed 6 years ago

SieKensou commented 7 years ago

Hi, first of all I have to congratulate you for the great job you are doing with this emulator. I tested the new 0.6.0 yesterday and it's great too see the new improvements. I'm using the Wii port version. I tested some GameBoy, GameBoy Color and GameBoy Advance games and I noticed that the Game Boy games doesn't sound very good. Some examples of the games I tested are: World Heroes 2 Jet (GB), Adventure Island (GB), Puchi Carat (GBC)... Do you think that the Game Boy sound could be better and improved for future versions?

Can you test the latest build? https://s3.amazonaws.com/mgba/mGBA-build-latest-wii.7z

SieKensou commented 7 years ago

When I tried to download from that link it saves a file called "mGBA-build-latest-wii.solitairetheme8" :/ No 7zip file or zip file...

endrift commented 7 years ago

Rename it. It's a 7z file, but your web browser screwed up.

SieKensou commented 7 years ago

Ok, that worked. Tested now and I can heard the same issues. I tested Donkey Kong Land too and I can hear some cracks in the sound between screens too.

Related to #1016.

Does this still reproduce?

SuperrSonic commented 6 years ago

I just tested the latest nightly and did notice constant crackling, I think this is a port-specific problem as I couldn't hear the same issue in retroarch wii and pc versions.

SieKensou commented 6 years ago

Yes, I tried the latest version (from 2018-08-01) and the sound of GB and GBC is still very bad. Even the sound when the GameBoy logo from the bios appear sounds bad.... Thank you very much for all the updates, this emulator is going better and better. Congratulations for the great job. I hope you can find what is happening with the sound of GB and GBC.

endrift commented 6 years ago

I'll try looking at the Wii port later; I'm not noticing the crackling on PC.

I'm able to reproduce this in Dolphin but I can't figure out what's going on. Before resampling everything looks fine. After resampling, things break. But only on the Wii, and the resampling code is the same in both places.

endrift commented 6 years ago

Fixed, at least within Dolphin. I'll reopen if it reproduces on hardware.

SieKensou commented 6 years ago

Nice! I have tested it and it sounds better than before, but the sound still has some problems. For example test the game Duck Tales and listen the first stage music for a while (you will notice again bad sound in some parts), In the same game, the music when you lose a life shows the problem.... and I notice it in other games too :(

endrift commented 6 years ago

That's probably #1036, not this one.

SieKensou commented 6 years ago

I think it is not exactly that one. I think it is related with some specific notes. Check the game I said if you can and you will hear it.
