UTM New release... With Screamer?

Post by adespoton »

From https://github.com/utmapp/UTM/releases
QEMU updated from v5.2.0 to v6.0.0
USB support: attach a USB device to the VM (macOS and jailbroken iOS 14.5 and below only)
UTM SE (Slow Edition): JITless iOS build available to sideload on any non-jailbroken device (thanks @ktemkin)
Screamer audio device for PPC mac99 machines (no setting changes needed)
Does this mean that QEMU 6 resolves the incompatibility between snapshotting and Screamer? I don't see anything in the QEMU changelog that would indicate so.

Not at all. And it still requires the purpose-built openbios.

I guess what you get is a build from Mark's screamer branch, warts and all. The current screamer code will crash Mac OS 9.0 and 9.1, but not 9.2 and above.
There is no warning included?

Best,

The odd thing is, I can't even see a screamer option in the actual provided build. I'm still trying to pull apart what they've actually done. The changelog doesn't appear to match the reality. I suspect the changelog is for a beta release and I downloaded their previous "stable" to test.

In the version I tested, UTM itself also doesn't appear to recognize/expose the monitor, and doesn't appear to have a concept of state saving.

[edit] I've now downloaded the latest beta whose changelog matches the "official" changelog. Still numerous bugs -- the default settings don't let you select a usable keyboard for 9.2.2, and Screamer isn't mentioned anywhere (although audio hardware is now disabled by default -- maybe that enables screamer? But if it does, that's rather counter-intuitive).

I guess this is a "watch this space" thing; they've made a few decisions that we've discovered cause issues, and their forum seems unaware of the problems.
