This does not improve graphics performance but helps CPU because it reduces
the number of bytes transfered to actual screen. I saw an improvement by up
to 26% in frameskip 4 800x600x16 but also a hit by 3% with frameskip 0.
The next step is to use NQD bounding boxes to help detecting dirty areas.
So far, this is the best I can do without VOSF working (MacOS X performance
bugs -- pitifully slow Mach syscalls)
- Properly handle migration from "screenmodes" and "windowmodes" to "screen"
- Fix has_mode() logic to really test for actual mode availability. i.e.
no longer start in large screen mode if user specified a max size.
- Call user handler for KERN_INVALID_ADDRESS too (SIGBUS)
- Check for VALID_THREAD_STATE_FLAVOR in forward_exception()
- Return KERN_FAILURE if forward_exception() got an unknown behavior code
Other bugs fixed:
- CD-ROM media are polled and now can be changed without rebooting
- Buffer overflow, memory leak and extra wait in CD-ROM ejection code
them. So, if someone has BeOS and wants to give it a try, please change and
test this new code. Corner case could be a resume_thread() when emul_thread
is not suspended.
Fixlet to powerrom_cpu: call idle_resume() from TriggerInterrupt().
prefs items changes but it should now be simpler to add other ethernet
emulation means (slirp, tap-win32).
# Basilisk II driver mode

as BasiliskIIGUI.app, or /Applications/BasiliskII.app if none was found.
Also make yet another arrangement for MacOS X "difference". This scenario
was not working: WarningAlert -> ErrorAlert, the latter was not performed
because the exit status was not properly filled in sip->si_status...
- Rewrote dispatch loop to accomodate GTK+1.2 for MacOS X (which doesn't
like threads nor forks(!)). The latter also requires an additional patch
to the version 0.7 available on SourceForge
- Run-time detect JIT capability so that we could hopefully use the ppc GUI
on intel based Macs (check!)
STANDALONE_GUI. This is the second step towards a more interesting GUI alike
to VMware. Communication from/to the GUI is held by some lightweight RPC.
Note: The step should be enough to provide a tiny GTK GUI for MacOS X.

This does improve slirp performance a lot, especially in FTP passive mode
transfers. i.e. now, they are equally as fast as non passive mode. I get
approx. 800 KB/sec in B2 and 500 KB/sec in SheepShaver (over a DSL line).
In native env, the max download data rate from my ISP is around 950 KB/sec.
