For demos and games written in Europe, use XL hardware/kernel, 320K RAM, and PAL.For newer games, use XL hardware and 128K RAM (XE), and use the XL kernel.For older games, use 800 hardware and 48K RAM, and the OS-B kernel.Disable BASIC (unless you're actually running a BASIC program).However, there can still be problems, some of which may be emulation bugs, and some of which are related to hardware emulation settings.

#ATARI EMULATOR FOR MAC SOFTWARE#

Its compatibility has been increasing over time, and at this point it should run most software correctly. Altirra is designed to emulate the actual Atari hardware as closely as possible. I'm afraid I can't offer these for download, but if you have downloaded ROM images from your Atari, Altirra uses the same format and filenames as most other popular Atari 8-bit system emulators. Therefore, you may want to consider hooking up real kernel ROM images, which will greatly increase Altirra's software compatibility. However, this kernel is reimplemented from scratch, and has some compatibility problems. Altirra has an internal kernel that can be used to run Atari software, and thus you can run demos, games, and productivity software without needing any Atari ROM images.

#ATARI EMULATOR FOR MAC PRO#

Specifically, disk images are supported in ATR, DCM, ATX, and PRO formats some simple cartridge types are also supported, and you can directly load Atari executables as well (.obx/.xex).

I can't give this to you for various reasons, but there are freely available demos, and if you have converted your Atari software to disk images for other emulators, those will work too. If you don't have any, it'll be a pretty boring experience. you need some actual 8-bit Atari (not Atari ST!) software to run. There is a README file in the archive, but here are some quick tips:įirst: Software. It's designed as a system emulator and debugger instead of a games machine, so there is some setup involved.

32-bit (x86), 64-bit (圆4), and ARM64 versions available.Īltirra is designed with emulation quality in mind, sometimes over speed and polish.

#ATARI EMULATOR FOR MAC WINDOWS#

Note: Neither the author nor the software on this page is affiliated with Atari, and there is no code or software from Atari included in the downloads. If you are struck by nostalgia too or have a desire to do some Atari development, perhaps it might be useful to you, too. It also serves as a modularity test for the VirtualDub code base, from which Altirra shares some components. This is the result.Īt this point, I've learned a lot more about the Atari and Altirra now emulates more than I ever had or did years ago, but I still work on it periodically. Over a decade later, I was struck by both nostalgia and ambition and started to write a new 8-bit Atari emulator from scratch. I had access to a number of 8-bit computers in my childhood, but my most favorite was the Atari 800, a 1.79MHz 6502-based computer with color graphics and a disk drive, and which as the predecessor to the Amiga, another favorite of mine.
