Sadly in next version of QEMU will be not present the new Pegasos II board on which Zoltan Balaton is working on. Meanwhile there was a great fix for Sam460ex board to prevents random gurus and and improved emulation od via-ide chipset.
For a complete Pegasos II usage there will be still needed ATI Radeon full emulation and some other stuff.
Zoltan said me maybe it could be done in a 5.1 or 5.2 version of QEMU, so on 3th or 4th quarter of 2020. I tried to support him with debug logs from a real Pegasos II, but I hope there will other people interested on it who can support in any way the project.
Remember a virtual board will be never broken and time after time it will be faster and faster with release of new cpus.. It can be considered also a good way to preserve from time our beloved Amigas and our history.
