One reason that this emulation was so successful is that many of the APIs for the Mac OS were originally implemented as traps on the 680x0 processor therefore, calling an API actually was recognised by the 680x0 as the equivalent of an error condition, which would cause it to handle that error through one of its hardware vectors. The 68LC040 had no floating point instructions, making this feat slightly simpler but no less impressive.

This emulator was theoretically capable of emulating 680x0 code faster than any real 680x0 was capable of running it. The emulator could recognise the same sequence of 680x0 code and run the previously-cached PowerPC code to avoid doing the translation again. Dynamic recompilation works by "recompiling" common sections of the code into faster, PowerPC-native, sequences that were locally cached. For the PCI PowerMacs, the dynamic recompilation emulator was used to boost performance. Early versions emulated it by decoding each instruction and immediately carrying out a series of equivalent PowerPC instructions. Apple developer documents indicate that the emulator provided an operating environment most closely resembling that of the Macintosh Centris 610, a system based on the Motorola 68LC040 microprocessor. Prior to Traut's arrival there, Connectix had released Speed Doubler, which included an even faster PowerPC 68k emulator.Īll versions of this emulator emulated the "user" subset of the 68EC040 instruction set with a 68020/68030 exception stack frame. A later version, using dynamic recompilation, was developed by Eric Traut, who later worked on successful emulation projects at Connectix such as Virtual Game Station and Virtual PC. It's ugly and contains a lot of hacks but it allows to boot Yaboot and BootX from HFS/HFS+ partitions.The first version was written by Gary Davidian, who had originally created it for use on the Motorola 88000 CPU, used in Apple's abortive first attempt at a RISC target platform. Sufficient to make the client think that it has USB support. NVRAM: Capable of storing 8KiB non-volatile memory. Network Controller: Emulates a 3COM 3C90x or RealTek 8139 via hosts that support an ethernet tunnel. VIA-Cuda: With attached Mouse and Keyboard. PIC: A programmable interrupt controller (kind of Heathrow). You can attach IDE-harddisk(s) and/or IDE-CDROM(s) by specifying files (or devices for UN*X) from your host machine. IDE-Controller: Sort of CMD646 with bus-mastering support. PCI-Brige: A barebone PCI-Bridge, enough to work with. Using this CPU, the client will run about 15 times slower than the host. By caching these translations, a lot of speed is gained. A very fast CPU for x86 systems that translates PowerPC instructions into x86 instructions on-demand.

As of version 0.4 the generic CPU emulation runs well even on big-endian and 64 bit platforms.ĬPU JITC-X86: Sort of G4, including altivec. Using this CPU, the client will run about 500 times slower than the host. See FAQ.ĬPU GENERIC: Sort of G4, including altivec. OpenBSD for PPC: Crashes while booting (accesses PCI in an unsupported way)ĪIX for PPC: Some people ask about that.

Mac OS X 10.3: Runs well with some caveats Mandrake Linux 9.1 for PPC after installation: Hard to boot. Mandrake Linux 9.1 for PPC installer: Runs well The following operating systems were tested and run (to some extent) in PearPC (ie. Supported host platforms: POSIX-X11 (Linux. Programming language: C++, C and (on x86 platforms) assembler PearPC is an architecture-independent PowerPC platform emulator capable of running most PowerPC operating systems. Only Executor does not require a ROM image. Most of these emulators require a ROM image and a copy of Mac OS. Regardless, it's no longer actively developed. It used to be a commercial product, but was later made a free download, then open-source. It is no longer actively developed.Įxecutor is a Windows/Linux emulator for 68xxx Macintoshes.

It used to be a commercial product, but it is now a free download. SoftMac is a windows-only emulator of 68xxx based Macintoshes. Good for earlier Mac games that were in color. Very handy.)īasilisk II is a Windows/Linux/OSX emulator that works as a virtual 68k Mac, and it runs runs Mac OS from 7.x to 8.1. (If you do own a modern Mac, look for "Chubby Bunny", a pirate release of the OS X version that comes preconfigured with Mac OS 9. This is probably the best replacement for Classic mode. SheepShaver is a Windows/Linux/OSX emulator that works as a virtual PowerPC, and it runs Mac OS from 7.5.2 to 9.0.4. It's great for games with black-and-white graphics. Mini vMac is a multiplatform virtual Macintosh Plus, and can run System from 1.1 to 7.5.5.
