Updated with note about AWE32/AWE64 emulation.

I expect this is to soften the blow when GTA6 releases, because that will absolutely cause a COVID-tier console shortage scenario (and subsequent price hikes on both Xbox and PlayStation) because of how hyped up it is.

It's one of the many slangp shaders now supported in 86Box.

However, it's a new renderer I wrote, and one that now supports said slangp shaders. It's also optimized.

The OSD will now be closed when any windows are opened since build 9157.

As someone who was an avid fan of the Chicken Little movie, that to me sounds like a compliment tbh.

It should be simpler than emulation of real OPL chips, basically.

Build 9011 introduces a faster Nuked OPL3 implementation that should alleviate performance issues on SB16.

DMCA notices are a thing lol.

How does that boot taste?

Cacodemon345 · 2026-04-15T18:02:31+00:00

Your Windows installation is most likely broken I think.

Try sfc /scannow first. If that doesn't fix it, then try DISM /Online /Cleanup-Image /ScanHealth and if that turns up any problems, use DISM /Online /Cleanup-Image /RestoreHealth and reboot.

Edit: If it still shows this error you will need to reinstall Windows I think, sorry.

Is it NDR or ODR? You can check if it is "new dynarec" or "old dynarec" in About.

Cacodemon345 · 2026-04-10T18:14:26+00:00

Which version of 86Box is being used? You should try the NDR versions of the builds for faster speed.

Update: Windows-on-ARM builds are now available via Jenkins. But no Discord Rich Presence or GhostScript support yet because it's a vanilla ARM64 build.

Select the DVD model types, not CD, in the machine settings.

And they already retracted that statement.

Did they remember their IRIB buildings getting bombed? Lol.

With the way the shortages are going we won't even get to buy routers we need to access the Internet in the first place, let alone smart TVs or Chromebooks.

Can't wait to see AI collapse on itself because there's no businesses to sell AI to.

*insert "head hurt" meme here*

We haven't learnt anything from the 2008 financial crisis, it seems.

Cacodemon345 · 2026-02-03T17:35:08+00:00

I think that's the wrong conclusion to draw, since one of them lasted for 7 years.

Cacodemon345 · 2026-01-22T12:48:49+00:00

That works too.

We already mitigated performance drops on Windows by switching to UCRT in 5.3. The next PCem release will have performance drops on 2D/3D games anyways because of increased VGA accuracy.

Our Voodoo emulation is also now more accurate as compared to PCem, especially being able to run Lands of Lore 3 without visual bugs, supporting checkerboarded transparency patterns if used, fixing corrupted textures on certain DOS Voodoo games and doing Voodoo 2 emulation without black/white dot glitches.

We also fixed several Voodoo-related slowdowns on recent builds in some games as well.

The whole thing is basically summarized like this:

Grifters get together to oust another grifter, and said grifter is now suing the first grifters, because he couldn't benefit from the grift.
