We have received reports @HyperDbg's latest release shows unexpected behavior. As it turns out, this is due to a compiler optimization bug in Visual Studio 17.14.8 and 17.14.9. We have pushed a temporary workaround fixing the build. Thanks for reporting! (1/2)
Apparently this issue is affecting others too. As we can't revert to older GH runner image versions, we will temporarily publish unoptimized release builds until MS pushes a fixed runner image. teapaw.org/rpcs3/status/194606920… github.com/actions/runner/is… (2/2)
Visual Studio 17.14.X compiler versions introduced a compiler optimisation bug, causing severe issues on RPCS3 such as missing game audio.
17.14.9 fixes it - we expect this version to be available on GitHub next week.
This is why there have been no builds for the last 4 weeks.

Thanks for all your positive comments! It's been great to present at #CCC for the first time :). If you have any questions, ask here on Twitter or just drop me an email. Live recording is already up at media.ccc.de/v/rc3-534188-wh… Slides are here: nautilus.bjornweb.nl/files/W… #rC3 #rC3r3s
I'll be presenting #Thunderspy at #rC3! Got a generous 1h time slot, so we'll be diving into more details, including mitigations we've been recently working on. Mark your calendars for Dec 29, 13h CET: pretalx.rc3.studio/rc3-chann… #CCC @ccc
Hey @IntelSecurity, will you be watching?
Join us tomorrow, Dec01 at 1800 CET, 900 PST for a #DS3Summit talk by the amazing @herbertbos from @vu5ec on why you have to rethink your threat model(s). Herbert is an amazing speaker, trust me, you don't want to miss his talk! ds3summit.github.io/#schedul…
Very excited to announce that today, we're releasing Thunderspy 2: two experimental projects that bring Kernel DMA Protection to all IOMMU-equipped Thunderbolt systems vulnerable to #Thunderspy. Find more details here: thunderspy.io/ts2.html @BlackHatEvents #BHUSA
We’ve got an announcement on #Thunderspy coming up today. Make sure to keep an eye out for my #BHUSA talk at 9:30 PM CEST / 12:30 PM PST! @BlackHatEvents
#BlackHat2020
If you use a Thunderbolt dock and your system ships Kernel DMA Protection, you might want to wait upgrading to Win 10 2004 for now: docs.microsoft.com/en-us/win…
Excited to be presenting Thunderspy at @BlackHatEvents in August! Keep an eye out for my talk "When Lightning Strikes Thrice: Breaking Thunderbolt 3 Security".⚡️ blackhat.com/us-20/briefings… #BHUSA #BlackHatUSA #BlackHat2020
This has been a long time coming. Today we release Thunderspy. Find full details at thunderspy.io. Thanks to @a_greenberg for reporting. #Thunderspy #Intel #Thunderbolt
Dutch researcher @0Xiphorushas has detailed a new physical access technique that could let hackers break into any of millions of PCs via their Thunderbolt ports. The good news is it requires unscrewing the case briefly. The bad news is it's unpatchable. wired.com/story/thunderspy-t…
If you ever wondered what this was about, watch this space (or head over to @WIRED) at 9pm EDT today. #Intel #Thunderbolt

Second day of @hardwear_io kicking off with a great keynote by @qrs on roots of trust and attestation in hardware
@DellCares Is it possible to get a refund for the Windows license bundled with my #XPS 15 9570? I won't be using it, and unlike XPS 13, there sadly seemed to be no option to order it with #Ubuntu.
