Libretro core - TBM - 08-21-2018

The libretro core has considerably worse video and audio quality than the standalone. What is causing this?


RE: Libretro core - endrift - 08-22-2018

What version of the standalone are you using?


RE: Libretro core - TBM - 08-22-2018

0.7-5003-789a84d2, and I'm using the most updated version of the core.


RE: Libretro core - endrift - 08-22-2018

That's pretty old. Try seeing if the latest standalone has the same issues


RE: Libretro core - TBM - 08-22-2018

Okay, so here's my finding with the audio. With 0.7-5003-789a84d2, there's no audio limiting and there seems to be no sound quality loss. With 0.7-5199-9ed127d5, there's a noticeable limiting, but no sound quality loss. With the newest Libretro core, there's limiting and a sound quality loss.

Here's the audio of all three. Same order as the screenshots: https://dbr.ee/xVtQ

Make sure you listen with headphones.

So in order, out of what I've tested. 0.7-5003-789a84d2 is the best, 0.7-5199-9ed127d5 is the second best, and the latest core is the worst. You'll notice how harsh 1 and 3 sound compared to 2.

Edit: I just tested 0.5.2 standalone and it's identical to 0.7-5003-789a84d2.

That's really strange, that uses GBA audio which I thought the only change I'd made between 5003 and 5199 was to increase the volume. Hm...can you see if 5113/5114 is where it breaks?


RE: Libretro core - TBM - 08-23-2018

Yep, that's it. Can you send me the Libretro core for 5113 or earlier? I'd like to test that too.
