EMULATOR FOR AMIGA MAC AND LINUX

Emulator For Amiga Mac And Linux

So, here it is.Welcome to the corner of Ultimate Amiga dedicated to running E-UAE, the cross-platform Amiga emulator, on Apple Macintosh OSX. It includes tons of pre-configured programs and it runs on Windows, Mac and Linux too.Gunnar asked that a new thread be started discussing Mac emulators. But if you want to experience a modern retro Amiga desktop showing how far ahead of its time the Amiga software design really was, AmiKit is what you want. Please scroll down for more sections and remember to share this page.To use Mac 800K disks, you have to own CrossMAC and an original Mac drive. Software emulation is roughly between 5 and 20 times slower than the hardware it emulates (emulators like the ShapeShifter 68K Mac emulator for the Amiga are an exception to this, because they do not need to emulate a CPU or custom chips).Welcome to the Apollo Forum This forum is for people interested in the APOLLO CPU.Commodore Amiga Emulators: Manufacturer : Commodore System : Amiga Welcome to the Commodore Amiga Emulator section of the Emulation Database. Possibly, this will mean 'Amiga Forever' in the literal sense.

FS-UAE is a great port I use on Mac and Amiberry or Amibian use the uae4arm port that runs on.When the last version of FUSION was released, there were only two programs that were known to not work with it. FUSION came from the Mac emulation that was released for the EMPLANT hardware that I created.00 Amiga DVD Emulator Pack for PC-Windows with Games. I also made FUSION-PC, which was a PC version that today runs circles around any real or FPGA based Amiga when using modern PC hardware. I am the creator of FUSION, the fastest and most compatible color Macintosh emulator ever made for the Amiga. As a result, the overall (subjective) feeling of the UAE and Fellow emulators is that a Pentium CPU running at 133 MHz. Since then, many platforms and CPUs doubled in speed every 12-24 months.

Now, to be clear, there are some programs that only work on certain Mac models. As far as I know everything else ever made for the Macintosh works. It was not possible to make either of these work and still have the Amiga function in the background, so these two programs were not supported.

The Mac OS *requires* 80 bit IEEE compliant functionality of the FPU (68881, 68882, or 68040). If Apple could have somehow made the mouse pointer position calculated with the FPU (instead of the ADB hardware), I am sure Apple would have done it! When a FPU is present, Apple uses it (instead of integer math) to calculate everything from basic math functions to window coordinates. If the programs says that it requires a Quadra, then it really requires a Quadra based machine which have 1MB ROMs.The Mac OS uses the FPU extensively. Make sure you look at the specs of the program you are trying to use - you could have the wrong system software and/or Mac ROMs for that program.

There are also other cases where crashes can occur, like switching screen modes since the FPU is used to calculate the screen size. Even with UAE (FS-UAE, WinUAE, etc.) it requires that '80-bit softfloat' be selected in order for any Mac emulator to work correctly. That is an example of something that doesn't crash, but there are some things that can crash such as various extensions like the TCP control, A/ROSE, AppleTalk, etc. A simple example is to install Mac OS8.1 and open a folder and try to use the window slider to move the contents of the window - the slider doesn't work and the slider size is not correct for the number of items contained in the folder.

You can't share system software between emulators. Silver series cores do not have FPU support so no FPU related issues occur as the built-in integer FPU emulation is done by the MacOS when no real FPU is present.One common myth that people have is that Macintosh hardfiles and partitions can be shared between FUSION and Shapeshifter and AMAX IV. There is no way to disable the FPU in the GOLD series cores.

However, you still can't share this system software with other emulators. If you do that, then you can change the amount of memory, ROMs, and video drivers without having to re-install the system software. You will need to force the MacOS to install the system software 'FOR ALL MAC MODELS'. This CD has system software for every MacII and later that was made. Apple made a version of the MacOS 8.1 installer called the 'Universal Installer CD'.

You can typically share partitions or hardfiles where applications have been installed. Just make separate MacOS boot partitions for your emulators. This was my biggest tech support headache back in the day. So, you will experience issues when trying to share the MacOS installation between emulators. The same partition or hardfile might appear to work between the emulators, but system resources are modified during the normal course of booting and running the OS, and that is something that Apple did not take care of correctly.

You don't need a CD-ROM drive anymore for CD support (making installation a whole lot easier considering that the Mac OS7.5 and later came only on CD!).People have asked for 'Vampire optimized' versions of FUSION and PCx. So, any version being tested should be an original licensed version if you expect it to work.I will be releasing new versions of FUSION and PCx (together as a package), both of which have new features such as improved video drivers, some internal fixes, and support for ISO disk images directly for CD's. Every 'cracked' version (often claiming to be some new release) is fake, and I have not seen a cracked version that removed all of the protection checks correctly. There were NO later versions.

In order to disable the FPU on a Mac you actually have to patch the Mac OS's to eliminate the hardware check, which requires some exception handlers and patching numerous system resources. You can do this in ASM with a MOVEC or with on CLI you can use for this the VCONTROL program.I recall very well that you tried out the Little-Endian MOVE in PCx and it did show a speedup.The speedup in total was not that huge mainly because of PCx having no JIT.If your average cost to 'emulate' 1 instruction is 3 Cycle - then saving 1 cycle will give you a major boost of 30%.But if your emulation has always a lot of overhead and your average cost is 30 cycle then saving 1 cycle is not a major boost anymore.Advertising your products will make a lot more sense again - if also some development was put in them.I don't think I am advertising anything, and I can remove the part about releasing new versions if you like.I wanted people to be aware of the issues when attempting to use the same system software between emulators, and FPU requirements for the Mac OS.The Mac does a hardware level check for the FPU, so you can't fool it by simply flipping a bit in the CCR. Type 'vcontrol fp 0' in shell and voila! no more FPU until power off.Jim, my understanding is that your goal to post here is to 'advertise' your products.I see that again and again put both Shapeshifter and PC-Task down,You also defame and repeatedly attacked the author of Shapeshifter.In your post I also see a number of technical interconnectedness.A) Its not true that you can not turn the FPU off.All you need it to poke the 'DISABLE FPU BIT' in the Processor control register. It turns out that the Apollo core's pipeline and caching mechanism works so well that the endian issues are absorbed.If you have any questions about FUSION or PCx, or Mac emulation I can answer them here or on my forums (Sean SkThere is no way to disable the FPU in the GOLD series cores.You can actually. I spent a few months tinkering with the using AMMX instructions with PCx, and there was no improvement that could be made by using any of the new instructions for doing things like swapping the endian order.

If your core actually disables the FPU instructions, so they generate exceptions instead of actually performing FPU instructions, then that would work.
