PearPC: simply because CPU emulator was really simple to detach from main PearPC code. QEMU: Not going to be possible without someone who knows QEMU inside out. CPU cores and JIT (TCG) is deeply connected to QEMU internals. Dolphin: If someone can guarantee PPC CPU is 100% 603/604 compatible, with some simple tweaks. (I don't think so). It is also console emulator (vs generic computer) and unused CPU features are rarely emulated (that may be used by some computer OS). Speed is not important, speed comes last if ever. Check any other emulator! Also, I have seen any qemu vs pearpc tests that actually compare same things. Exact same code generated by exact same compiler running on exact same OS and code that does not depend on any hardware expansions, just pure CPU. Quote:

PearPC was choosen because it was the easiest to implement according to Toni Wilen. And he has never had that much intresst in PPC so he took the quickest road to get results and thats it. And why he didnt activate JIT to start with is that its easier to debug without. When he reaches what he thinks is enough he will activate JIT and if it works fine, if not then it will be left out, But its open source so "anyone" can replace the PPC part with another. EDIT: i was to late see Toni´s answer instead. |

That's very interesting. Do you remember that I can not boot my AmiKit Real with the BPPC config I posted? CWB works with that config. And now, with my CSPPC config I can boot and run AK Real but it can't boot CWB. I get a black screen with it and not even F12 works... |

I normally tell it to reboot, then cancel the reboot and it seems to force kill winuae. Saves rebooting then. |

If you are at all interested in getting a copy, now may be the time to buy, especially before the few places selling it realize that there is a newfound demand for it. I didn't wait until they were out of stock. Just a bit of advice. |

I'm sure if there's demand it will be easy enough to restock, thety are just printed boxes with manuals and printed CDROM, it's very cheap and fast to get such an item produced.
@Toni, Is it possible that the 3D Hardware Effects in OS4.1 under Radeon Cards would work on WinUAE? Steve. |

Can anyone here that's had experience with OS4.1 (or 4.0) for Classic systems tell me if the boot diskette is absolutely necessary, and what's on it? Is it required to install the OS, and/or is it available in .adf?

If you really need boot disk, just use the cd in WB3.9 and create the boot floppy from there. |

IIRC there is an ADF of the install floppy on the CD.
CSPPC users can just boot from SCSI CDROM to install, A1200 users will need to boot from floppy to get the CDROM driver loaded and continue booting from CD. This is because BPPC's SCSI isn't supported by OS4.x If you talk about WinUAE I guess it should be possible just to boot from the CD? |

@Retrofan
I didn't mean a listing of the files on it, but just info on what it's for, what it does, and if it's necessary. @FOL The installation script works on 3.9? Thanks both of you, & fitzsteve. |

I wonder when the first emulated AOS4.1 classic thread will appear in the Hyperion support forum?

About QEMU and Dolphin:
Dolphin does not support MMU in JIT modes (Non-JIT MMU is also only experimental). Also it does not support all integer exceptions (for example overflow/division by zero), [EDIT: general purpose computer] emulator that does not run buggy/crashing programs correctly (without crashing emulator or emulated operating system) is not that useful. PearPC has same problem, minimal exception support. It leaves QEMU which seems to do everything. Which is unfortunately also the most complex beast with huge dependencies with other QEMU modules and objects.. Including GCC-only features. |
