- When loading old config which has both cycle-exact and fastest possible enabled: disable fastest possible. Previously this combination was invalid but some for some reason old configs can have both set.
This is broken. It always sets speed to approximate, even when cycle_exact was not set in config file. (and config was saved with 2.8.1 or older)

If you are wondering why all old fast configs are suddenly slow.. Just tick fastest possible as a workaround.

Some infos/findings regarding PPC if can help somehow...

https://www.debian.org/ports/powerpc/inst/apus

also...
http://en.wikipedia.org/wiki/WarpOS (Notes 1. WarpUP, Notes 3. EHF specifications, Notes 4. BlizzardPPC Flash ... but other Notes might be also interesting)

Maybe looking into WarpUP docs, hwdrivers (and sources) can somehow help -> http://download.haage-partner.de/Amiga/WarpUP/

I have tried to boot up OS4 Classic, i know it won't run.
But i think or hope, it will help you in some way.
I used the last beta you have posted.

btw. nice warning

Does not help. I already said linux or other os that takes over the system simply stops the m68k after ppc has been started and forgets about m68k completely. This is not how powerup running with amigaos works.

Hardware is officially undocumented.

That message is gone in next version and most likely ppc emulator will execute at least some instructions before it probably dies for some unknown reason..

btw, could someone list urls to csppc/bppc compatible netbsd or linux kernels? I only need bootloader + kernel to test if switching off m68k works correctly.

Don't know if this helps:

@Toni: Ralph Schmidt of MorphOS-team should know how this works - AFAIR he wrote the PUP-software. Same applies to Sam Jordan (WarpUp / dunno if he still works for H&P)

I know (quite obvious by looking at flash image dumps ) but I am not interested to find contact addresses of old developers and even less interested to find if there are conflict of interests (for example still developing non-free Amiga software, wrote some NDA long time ago, etc..). I have had annoying experiences.

In other words: it is someone else's problem (again) to find if he/she is friendly with emulation or not

Yeah, agree ... it is someone else's problem!

p.s. Sounds like a fear of (un)success!

I tested few randomly chosen WarpOS executables from Aminet. All of them worked just fine. I didn't expect it

Still todo: missing hardware feature that PowerUP needs.

Great. Does the PowerUp-emulation under WarpOS also work? (or it needs missing HW feature too)

Also, does it work on BPPC after BPPC fix applied ? http://powerup.amigaworld.de/index.php?lang=en&page=13

Maybe some demos to test also -> http://powerup.amigaworld.de/index.php?lang=en&page=32

p.s. and some f.a.q. what is word about -> http://powerup.amigaworld.de/index.php?lang=en&page=37

p.s.2. In other words, who cares about PowerUp anyway ?!

I don't care about PPC software. Software just works when hardware is emulated correctly, PowerUP that does not work (because of missing hardware bits) makes no difference. Hardware needs to be emulated.

Me too. (would like more to have better CE on A1200 instead, but it was your decision to move on something else)

p.s. But when so much has already been achieved, it would be a shame not to finish the job properly.

Excellent.
If we get to the point where Wipeout2097 and Shogo run then I would be delighted!!

What software did you test?

Hmm.. I think I tested SManWOSB2, PPCjpeg, unlzxWOS and wos vbcc (from official page).

btw, everyone should still remember that "working" means it seems to start and does not crash, nothing about speed or if it fully works, I don't even know or care how fast they run on real hardware. (and JIT version of PearPC code is not even in use yet, compatibility first!)

Thanks Toni.
My biggest Amiga regret is selling my BPPC A1200 Tower system.
Really excited at the prospect of one day being able to run my long sold BPPC OS3.9 install in WinUAE.

There is also one very important reason to get PowerUP working. BPPC has it in flash rom and it runs during boot, currently it does invalid accesses and most likely also corrupts memory. (It does not help even if powerup gets replaced with warpos after boot code has run. It is too late.)

PPC NetBSD also boots and then crashes. Again, still much better than I expected

Errors logged by PPC emu:

Code:
[PPC/DEC] Bad opcode: 00010203 (0:257)
singlestep set from ..\..\ppc\pearpc\cpu\cpu_generic\ppc_dec.cpp:96, info: unknown instruction

[CPU/EXC] <Warning> pc == 0 in ISI
singlestep set from ..\..\ppc\pearpc\cpu\cpu_generic\ppc_exc.cpp:54, info:
Next beta will be out tomorrow.

EDIT: CPU crash fixed, it was interrupt handling bug. Now it "only" hangs in Cyberstorm NCR SCSI driver, probably due to lack of some 53c770 specific stuff in emulation. (I guess m68k netbsd would also hang identically)
