Turning an OS 9 app into an OS X app was not trivial, despite various compatibility layers, so there were a lot of developers, especially for already-released games, who didn't bother. But with the intel macs, they've dropped that support (not too surprising really, given that OS X is 6-10 years old now depending on how you count, and it must have been getting more and more painful to keep classic working, especially with the new chips). The emulation wasn't perfect and didn't tend to do well on system 7/8 games. Many G3s and some G4s could dual-boot the two (in the same sense you might have windows and linux dual-booting), and most powerpc machines (all?) supported the 'classic' environment which emulated OS 9. Apple's switch to OS X amounted to completely scrapping OS 9 (well, I doubt that is really true, since probably a lot of the OS 9 developers' expertise went in to modernizing NEXTSTEP). Around 1997, Apple bought NeXT (which incidentally had been Steve Job's startup after Apple kicked him out in the mid-80s this is when he came back to apple, and it was probably one of the best things they ever did). It is built on top of BSD unix and descended from 'NEXTSTEP', a really-ahead-of-its-time unix/window-server from the late-80s/early 90s with objective c as the main development language.

To answer this part of the question: OS X is a radically different OS in almost every way from OS 9/8/7/etc. and I was wondering whether the latest OS, or maybe the new chips, changed everything.

This has been a personal project for me for a while and I hope my work is helpful.They have a patch for purposes of OS 9, but not later. I hope that somebody finds this info useful and can make some progress! I haven't seen this documented anywhere else online (and believe me, I have spent hours looking) so I think in any case it's good to lay out the patches I've found so far. I'm new here and still trying to meet the 3 post quota (please approve this!) so I'm not sure if this fits your interests. If this were achieved, D11 would have a much higher chance of booting than D7 and D9, since it supports PCI-based Power MacsĪnyways, this is getting long.

#Installing games on sheepshaver manual#

Possible leads most likely require further analysis of the installer script and perhaps manual copying/creation of the expected volume scheme to create a bootable system I believe this is because the installer can't write a boot partition at all, preventing any progress in booting at all SheepShaver segfaults during the happy Mac before any Copland-related code loads (looks like it doesn't even load boot resources)

The installer script can be modified in Resourcerer to bypass the checks for a compatible Macintosh and partition scheme Possible leads include further analysis of nkld and ModernOSLoader or modifications to SheepShaver itself so that it more accurately emulates a 6100, 7100, or 8100 device-tree, allowing Copland to find the 'GDevice' without modifications Installing a game on Sheepshaver About SheepShaver, a PPC Mac emulator for Windows, MacOS X, and Linux that can run System 7.5.3 to MacOS 9.0.4.

And that's about all I've figured out so far. Segmentation fault, crashing the emulator With some NOPs in the nkld code (use Resourcerer), this error can be bypassed, and the boot process proceeds as follows: This resource draws the boot screen and finds devices and volumes, and eventually shows the 'Failed to find main GDevice' error The codes in the boot resources #1-3 run first, and call the nkld resource ('NuKernel loader' perhaps?) The initial boot code is inside the System suitcase on the 7.5 volume ('scarecrow volume')

How To Install Games On Sheepshaver For Mac Mojave.

(Versions that run on Windows and Linux also exist.) SheepShaver lets you run any older system between Mac OS 8.5 and Mac OS 9.0.4. They expect a NuBus based Power Mac, SheepShaver emulates a PCI one The Mac version of SheepShaver is a universal binary, so it runs natively on an Intel-based Mac. I've made the following discoveries, resulting in somewhat more progress: Custom Drive Setup bundled with it can't initialize SheepShaver's weird 'big floppy disk' drives Can't be installed in SheepShaver because it needs a weird partition scheme Boot messages and eventual error are the same, but the graphics are more polished

Installable in SheepShaver by manually following the install instructions that come with the software I've tested 3 builds, to different results: It would be really awesome to get this working on a modern machine since Power Macs aren't super easy to come by anymore. I thought I would quickly summarize my efforts/progress and see if anybody wants to help out. Hey all! As far as I know, nobody has really put much effort into installing any Copland builds in an emulator.
