WinUAE 3.0.0 beta series (was 2.8.2/2.9.0)

[amilo3438]

http://www.amigahistory.co.uk/ppcseries.html

On above link its said:

The G3 is a considerable improvement on the 604 design rendering a great deal of software incompatible.

The PearPC emu use only G3 and G4 PPC CPU emulation (one of CPUs currently you're trying to implement into WinUAE), but BPPC needs 603e and CSPPC needs 604e that were emulated in QEMU and this unfortunately looks complicated to implement into WinUAE (what you said). Thus, according to above quote, could be expected some great software incompatibility from the G3/G4 emulation anyway.

EDIT: Mess emu might have those CPUs emulated, but dont know how good ... also it seems the license might be not compatible with the WinUAE anyway.

EDIT2: So this G3/G4 CPUs might be good enough only for an AmigaOne emulation (in case you change your mind -> http://www.amigahistory.co.uk/eye_amyone.html)

I'm glad to hear that still does not give up.

p.s. Perhaps you meant to say: "fastest possible cycle exact" not accurate enough mode !

I'm just glad you're doing this for us, Toni. It's really, really fantastic of you. came early this year!

I'd like to (JUST FOR S&G!) have an OS4 classic and (separate) BSD emulation going to boot up and play with from time to time.

You are awesome! Keep at it dogg.

I keep getting an error message "One of the following system ROMs is required:

- Blizzard 1230-IV ROM (32k)

Check the System ROM path in the Paths panel and click Rescan ROMs." and then I immediately go to the classic kickstart ROM screen. No indication the Blizzard 1230-IV is working. If I select different type of PPC like Blizzard 1260, I still get the same error message.

Is there a place where I can download the rom or what advice do you have? I tried the test powerPC disk but it failed with no ppc.library available, PCInstall failed returncode 20. If I do WarpOS test it just crashes the emulator and restarts again.

The accelerators roms are in the Zone ("accelerator_roms").

"How do I get access to the zone?
Easy, you just need to join the 'Access - The Zone!' group.

To join:

1) Click on 'User CP' (top left of screen)

2) Click on 'Group Memberships' (bottom left under Miscellaneous)

3) Then Click 'Join Group'

Please Note:

DO NOT upload IPF images, Workbench disks, Kickstart ROMs & software or music files still supported/for sale to The Zone.
Also Please don't direct link to files in The Zone when creating a 'new thread' or 'replying to a post'"

[xboxown]

Thank you! I got the thing working! Thanks again

[turrican3]

Thank you tony to try to make ppc emulation possible.
If it works the numbers of amiga os 4 on the market will break all records !

Np Tony
I understand that.. Blood Money is obviously an oddball case that accidentally works on occasion. I only mention because it seemed directly affected with latest update.

WHD games consist of 90% of what I do on winuae.. Do you want me to still report problems in the future, when you are working on CE improvements?
There are cases where some games run more accurately with CE off.
Surely WHD compatibility reports aren't completely useless, are they?

@Toni Wilen

It's awesome you got some PPC stuff working, good job!

[mark_k]

Regarding PowerPC emulation, did you consider the PPC cores used by Dolphin, the GameCube/Wii emulator?

Dolphin is license-compatible (GNU GPL version 2). It has three PPC cores: interpreted, JIT, and JITIL (there's also an ARM core). However it seems that in recent source the 32-bit JIT has been removed. Could be kind of ironic, you could have a 64-bit WinUAE-with-PPC build that has JIT for PPC but not M68K.

You can browse the source here.

previous releases: test completes with a brief hang reporting CPU speed of 29.. normal behavior (see pic 1)

beta 8: test freezes during "computing mflops" for a huge amount of time then reports abnormal speed of 16.. or freezes indefinitely. Both times I tried this with quickstart it froze forever (see pic 2)

Sorry, but have similar problem (quoted config is patched) with another config (latest betas) select:
- Quickstart A1200 + 4MB fast
- CPU 68040 and CPU Frequency 8x
- boot into Workbench and run SysInfo -> Speed
causes Reset and "Software Failure".
PS. 68030 is working fine.

[Toni Wilen]

Note to "outside" observers: my goal (if there even is any), is to run some simple PPC programs that work under AOS3, just because you can, perhaps also see what happens with netbsd and linux. Thats all. Do not expect anything else, do not assume anything else. At least not for free.

It shouldn't unless your config was not "normal". (68030+ cycle exact has changed). There is only real change if 68020 (or lower) mode works now differently.

No, mostly useless only. Only obvious huge glitches are acceptable if it can't be duplicate using original version using original configuration.

Yes but consoles rarely have same CPU, some features may be cut, some added and so on.

PearPC only because it was simplest. So far QEMU is still the best option, it is the most compatible. Speed is irrelevant. (and not enough inspiration)

Not a bug (and nothing to with CPU frequency) and didn't you even test with previous version?

Sysinfo don't like 68040's without FPU.

OK, SysInfo on 68040 with FPU is working very fine Thanks!

Thanks toni, I normally use 030 (didn't know 030+ had changed). I tried the latest winuae.zip with 020 and it's working properly like beta 8.

What is with SheepShaver or is the PPC Part useless for WinUAE ?

Is Toni actually going to add PPC emulation? Here I am sitting here thinking that he would never add PPC because he says so. I have a motto that I always follow. It is "Expect the unexpected".

Now I wasted time running the 68K version of Payback.

[Mad-Matt]

How was that a waste of time? Payback 68k runs really well as it is with hardware accelerated 3d as well.

[huepper]

Hello Tony, thanks for your work on (partially) PPC-Emulation.
I have tested setups with Blizzard PPC and Cyberstorm PPC.

With Blizzard PPC i will have no fast memory on WB. (set to 128 MB)
With Cyberstorm PPC the 128 MB will appear.

I couldn't run via hardware mode; only with software mode ATM. I do have to admit that the isometric mode you get in HW mode looks rather good.

Works in my version so I guess it is already fixed.

Yes. But there are some IFs: No working PPC emulation if PPC emulator core is not good enough or has bugs (Using QEMU PPC core won't be easy). I don't debug PPC code. No working PPC emulator if no one knows or (possibly accidentally solves) how CSPPC/BPPC interrupt related registers work.

My work is done when some PPC test program runs correctly. The rest is probably Someone Else's Problem.

Useless. No MMU and also it seems to be incomplete. (Not all instructions are emulated)
