Qemu, on the other hand, emulates the entire hardware chain, so disk processes have to be handled by a lot more virtual hardware prior to reads and writes. SheepShaver improves Disk I/O by patching the ROM so that I/O is managed by the host, not the guest system. One of the main bottlenecks in qemu appears to be disk I/O, and using raw block devices on a fast host storage device seems to improve things significantly. Surprisingly, this is with Quickdraw 3D 1.6, which would crash Sheepshaver any time you opened a 3DMF file with 1.6 rather than 1.5.4 or older.Ĭlasilla 9.3.3 - You can start this up fine and it appears to work, but I'm not sure how well the Internet works yet.ĭo you have the software you used for the speedrun available? I've got some Minis I could run the tests on for a comparison.Īlso, I'd like to run a few tests on my system, which mounts drives as block devices off a high speed SSD. 3D objects do appear without crashing, although I suspect rotating them would be very slow. Scrapbook - As before, you can see the 2D pictures, which render faster in 2.8. If this happens, quite out of Reader 5 and re-open it. Also, when switching between fullscreen and windowed in QEMU, the buttons on the top can't be clicked on, since doing so always results in the right-click/control-click menu appearing (and this is without holding Control down, like you usually do). I've yet to install 9.1 or 9.2 onto a hard disk, though it wouldn't seem like either of those work from a hard drive at this point.Īpple System Profiler - As I do use mac99, this appears to work fine.Īcrobat Reader 5 - You can open documents just fine, but trying to use the scroll bar after switching between fullscreen and windowed doesn't work. Stuff-It Expander (any version really, versions 5-9 preferred) Gravity (extension that allows for gravity on the Mac OS Desktop a real test for floating point emulation and possibly the MMU too) Gerbils (Quickdraw 3D demo included with Macs until 8.5)Īpeiron (Notable for having mouse problems on just about every emulator, even having problems on several real Macs) Scrapbook - Can't be tested, since this is a built-in component for Mac OS Classic and not part of the CD Extras folder. HyperCard Player - The sample app does seem to work fine, not sure about the other Hypercard stacks. Scrapbook - The included 2D pictures do render.slowly, but 3D objects in the Scrapbook have not been tested yet (these do require Quickdraw 3D). QuickTime 6.0.3 - Boots up, but no tests done on individual videos or images yet. Could be a graphic memory allocation issue. Watch out for any NaN cases, as those can trip up any PPC emulator.Įric's Solitaire Sample(r) - Booting up from the CD doesn't work - it complains about not being able to read the preferences folder (not a big deal), but crashing with a fatal error message saying that it couldn't allocate memory to a GWorld (GWorld being an instance of the game's playing field). Graphing Calculator - Seems to be (mostly) right, although the 3D animations go very slow. Mac OS 9.2.1 (Install CD) + Mac OS 9.2.2 (Modified Install CD) QEMU 2.7.0-rc0 w/ OpenBIOS compiled on July 19, 2016 With the recent confirmation that QEMU can run Mac OS 9.1 and 9.2 by default, I've decided to test what I can run by default. This was originally posted in the QEMU megatopic, but was split off due to that topic's enormous size.
