/r/Emulation does not support piracy. This is better for keeping things clean and organized, and is easier to troubleshoot (and Im sure a lot of troubleshooting will be necessary for that one). You can also join us on Discord!Definitely its own page, just like how we dont add Mac OS 9.2.2 compilations that work in previously-unsupported hardware to the main Mac OS 9 page. It is an architecture-independent PowerPC platform emulator capable of running different PowerPC OS including the pre-Intel versions of the Linux, Darwin & the MAC OS X.Citrix Workspace app is a new client from Citrix that works similar to Citrix Receiver and is fully backward-compatible with your organizations Citrix.To get started check out our wiki page or The Emulation General Wiki.

Use Google and check The Emulation General Wiki before posting. Darwin is the open-source foundation of Mac OS-X, and OpenDarwin is the community.Users are permitted to post one emulator demonstration video per day as a link post.

Sheepshaver does numerous ROM patches to avoid having to emulate the MMU (or most of the registers involved) at any cost. I do realize a good chunk of Mac users aren't coders, but that doesn't mean coders won't have a huge number of obstacles too.The PowerPC CPU is rather complex, probably not as bad as a x86 CPU emulator, but definitely not trivial either.

Send the moderators a message if you'd like a user flair reflecting that.Since QEMU has is pulling way ahead of Sheepshaver and PearPC in terms of hardware accuracy (it can emulate PPC Mac OS 9.1-10.4), I figured I would have a go at describing the issues of writing a PPC Mac emulator, including by comparing it to the other PPC emulators that are known to be able to run PowerPC Mac OS Classic or X.Popularity aside, there's plenty of technical difficulties regarding Mac emulation. At least PearPC tries MMU emulation.There's also the rest of the hardware, where crucial components like audio chips and hard drive controllers are seemingly proprietary. On the other, you still have to deal with a pretty capable MMU. On the one hand, this means that 32-bit PPC Macs can only address up to 4 GB, making it relatively feasible on 64-bit machines. Doing a G4 is somewhat harder, due to the nature of AltiVec.Macs themselves also are partially based on the PowerPC Reference Platform (PReP). If it's any consolation, the video cards in most PPC Macs are pretty much the same NVidia and ATI cards seen in PCs. In general though, Apple doesn't really have much on its own old hardware. It doesn't help that the best thing I found was in Apple's own sources. Re-implementing these ROMs is possible, but would a very laborious task and would require a ton of people to dig through and carefully document how these work.There's probably many more issues, but these are the ones I found noteworthy. Even not regarding legal issues, they are very different internally and are coded to work with specific hardware set-ups. Both Sheepshaver and PearPC use barebones drivers just good enough for displaying images, but not so much acceleration.Lastly, there's dealing with Old World and New World ROMs. To try and port dolphin to run on a big endian system would be a nightmare.As for just using dolphin's JIT/interpeter as a generic PowerPC, the biggest problems I see are MMU and Usermode.Dolphin's MMU code has improved a lot over the last 5 years and it's actually reasonably accurate by now, though I wouldn't be surprised if there are still missing features. Sheepshaver is also tricky to get compiling at all unless you're using late GCC 3.x or early GCC 4.x, but various unofficial branches have attempted to address this.As for re-implementations of PowerPC Macs, the most complete one I found was Classix, and even that could only run basic applications at best.Dolphin is hardcoded to run the PowerPC in big endian mode.Dolphin's issues with endianness and people wanting to port it to PowerPC are not that gamecube/wii games are little endian, but that dolphin is hardcoded to always swap bytes.The code to swap endiness is smeared throughout the entire codebase, there is no nice clean generic swap function that is used everywhere. Coincidentally, the last official update for Sheepshaver was only a few months afterward. PearPC was coded for more modern x86 and x86-64 machines, but interest dropped off the map not long after Intel Macs were announced. ![]() Ppc Emulator PS3 Where GamesShouldn't be too hard to implement usermode. Though that puts you in a lot better place than emulators for more modern consoles like the WiiU or PS3 where games exclusively run in Usermode.But dolphin does understand the concept of multiple modes, with accurate switching between supervisor and real mode.
