Welcome to Darek Mihocka's Emulators web site. Since 1986 we have pioneered techniques for running Atari and Apple Macintosh software on PCs. Years before Apple made.

This software synth turns your VST, AU, RTAS or AAX host into a classic video game console, vintage 8-bit home computer and even an 80 Stella is a multi-platform Atari 2600 VCS emulator. It allows you to play all of your favorite Atari 2600. Altirra, an 8- bit Atari computer emulator I had access to a number of 8- bit computers in my childhood, but my most favorite was the Atari 8. MHz 6. 50. 2- based computer with color graphics and a disk drive, and which as the predecessor to the Amiga, another favorite of mine. Over a decade later, I was struck by both nostalgia and ambition and started to write a new 8- bit Atari emulator from scratch. This is the result. At 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. It also serves as a modularity test for the Virtual. Dub code base, from which Altirra shares some components. ![]() If you are struck by nostalgia too or have a desire to do some Atari development, perhaps it might be useful to you, too.

Before you begin Altirra is designed with emulation quality in mind, sometimes over speed and polish. It's designed as a system emulator and debugger instead of a games machine, so there is some setup involved. There is a README file in the archive, but here are some quick tips: First: Software. If you don't have any, it'll be a pretty boring experience. 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. 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 (. Second: kernel ROMs. 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. However, this kernel is reimplemented from scratch, and has some compatibility problems. Therefore, you may want to consider hooking up real kernel ROM images, which will greatly increase Altirra's software compatibility. 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. Third: compatibility. Altirra is designed to emulate the actual Atari hardware as closely as possible. Its compatibility has been increasing over time, and at this point it should run most software correctly. However, there can still be problems, some of which may be emulation bugs, and some of which are related to hardware emulation settings. Tips: Disable BASIC (unless you're actually running a BASIC program). For older games, use 8. K RAM, and the OS- B kernel. For newer games, use XL hardware and 1. K RAM (XE), and use the XL kernel. For demos and games written in Europe, use XL hardware/kernel, 3. K RAM, and PAL. If you don't have kernel ROM images, use the HLE kernel instead. Use Input > Joystick to toggle the joystick, which uses the arrow keys and the left control key. Downloads Altirra is licensed under the GNU General Public License (GPL), version 2. Binaries (i. e.
