Major milestone forward for HyperDbg supporting #Linux. We've made a major progress on porting HyperDbg to Linux (still a long road ahead). Now the HyperDbg SDK can be compiled with GCC for both user/kernel modes on Linux. More updates coming soon...👀 github.com/HyperDbg/HyperDbg…

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. xitter.cf/rpcs3/status/194606920… github.com/actions/runner/is… (2/2)
RPCS3
@rpcs318 Jul 2025
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.
