Amiga emulator ppc mac mac#

MacOS Big Sur and supports Mac computers with Apple silicon. Today, a new version of vAmiga has been released. vAmiga 0.9.17 released vAmiga 0.9.16.2 with ARM support released Therefore I think it is time to say goodbye to the 0.9 release scheme. vAmiga 1.0 Beta 1 releasedДЄlthough not perfect yet (it will never be), vAmiga has proven to be pretty stableД«y now. The video was recorded using the emulator's screen capture function. The Amiga PreRelease of Athanor 2 - Legend of the Birdmen. Other emulator makers, I would never have gotten this far with this project. Without the valuable advice from coders, testers and I would like to take this opportunity to thank all those who helped me realize theД®mulator during this long time. vAmiga 1.0 releasedДЄfter two and a half years of development, I am proud to announce the release of V1.0.

It reveals some of the graphics tricks of this great demo. Watch Rink a Dink: REDUX (Lemon) running in vAmiga with the DMA debuggerД®nabled. The second one runs the demo in the DMA debugger. Two more videos uploadedД«oth show The Black Lotus (Eon) running in vAmiga.

Amiga emulator ppc mac update#

This version is a small update fixing some crashes that were reported for v1.0.

In warp mode, vAmiga 1.1 runs up to 15% faster than the previous version. Last but not least, the speed of the emulator has been optimized. Now changing disks is even simpler than it already was in the old version. The biggest change from a user's point of view is the newly added drop layer, which automatically blends in when a media file (ADF, DMS, etc.) is dragged into the emulator. For this reason, the new version is released as a beta version first. However, due to the far-reaching changes, it is likely that one or the other bug has found its way in. In the process of refactoring, many internal changes have been made that are not noticeable to the user. This effort will ease the maintenance of both emulators in future.

Amiga emulator ppc mac code#

My goal was to align the code bases of both emulators as much as possible, which I managed to do to a large extent. I have reserved the Amiga chipset address space in the emulator's memory so I can emulate any required hardware.During the last weeks I worked a lot on the code base of vAmiga and VirtualC64. The Amiga hardware, many Amiga programs assume the custom chips will be present.

Amiga emulator ppc mac full#

I had originally hoped to let the 68k have full access to the memory, but instead I have to limit it to a 4gig single allocation.Д¤. This is the biggest issue as it means all memory access must be mapped. this is something which I didn't originally think about, but the Host Operating system uses a 64bit address space, and Amiga Apps are stuck in a 32bit space.

I solved this by building a set of classes which map over the Amiga operating system data structures and handle the endian issues.ДЈ. all data structures on the Amiga are big endian, so all multibyte memory access needs to be byte swapped when the host operating needs to manipulate them. The 68k CPU, not to much of a problem, but obviously requires an emulator (which reduces the performance).Дў. This approach is hampered by four things:ДЎ.

Amiga emulator ppc mac windows#

Essentially how Wine works when running Windows Instead of simply emulating the whole Amiga architecture, I trap application calls to Exec, Dos (and other hardware hitting libraries, devices, and resources) then handling them with the host operating system. So why not point it at an Amiga executable and see what it doesДЄs explained, I am trying a different approach to Amiga Emulation. It doesn't really do much at the moment, so I've included a 68000 disassembler, so you can watch the instructions execute. The rest of the ram isn't available to my exec emulation and currently does nothing.

The emulator allocates 16Meg of ram, of which the lower 2Mb is treated as Chip Ram, and the next 8Meg is treated as Fast Ram. Other libraries are just Stubbs right now, which do little except report which function has been called. The minimal DOS library currently just access the Mac file system, and is only able to loadSeg executables into memory, and then CreateProc them into the multitasking system. I decided to build this separately from ADFBench for now, so I can et it working properly before I reintegrate back in.ДЄllows task to send and receive signals, but the message passing system is not really working yet. Well, after quite a bit of effort, I have a working alpha of the emulation engine running. As promised here is an early alpha of my new amiga emulator.ДЇor those of you who have used my ADFBench, you will be aware that I set about trying to get my ADF browser to actually run the amiga executables it can read on ADF files.
