Well, my plans for SheepShaver reduced as other projects went on and/or=20=

resurrected. As of today, I would like to focus on:

- Better integration on the MacOS X platform: add the new GUI and=20
possibly drop SDL support in favor of native audio (from B2) and OpenGL=20=

graphics. The latter doesn't mean 3D acceleration but use of e.g.=20
GL_UNPACK_CLIENT_STORAGE_APPLE and other OSX specifics to improve=20
graphics performance.

- Add a native_powerpc_cpu emulator for PowerPC platforms: i.e. an=20
alternative method to reach near-native performance on ppc instead of=20
using direct execution of ppc code (and its problems). This will bring=20=

support for ppc64 host platforms + reoptimization for Cell (and whatnot=20=

splitting instructions to avoid microcoded instructions).

The JIT rewrite is retargetted to another project.

slirp mode also works on Windows.

Well, I am not a windows developer and I have very little knowledge in=20=

that field.

Do you mean that the B2-ether driver works fine with Basilisk II but=20
not with SheepShaver? One difficulty of the Windows port is that this=20
platform doesn't support mappings of the first segment (64K at address=20=

0). Hence a few hacks are used to keep the adress space consistent but=20=

the behaviour of Windows is unpredictable and might trash the mappings=20=

we had. And the initial ethernet code relied on a V=3DP mapping, not=20
V=3DP+offset (where P=3DHost(Windows) VA, V=3DGuest(MacOS) VA, =
VA=3Dvirtual=20
address). I tried to fix but it's probably not perfect yet.

Can you check whether slirp works without crashing on your platform?=
