Altirra is an 8-bit Atari emulator, thanks to which, on a computer with the Windows operating system, we will launch classic games available exclusively on Atari. The emulator has an internal core, allowing you to run selected games or programs without the need to install ROMs, the manufacturer does not recommend using this solution. He explains that the internal kernel implemented here has been written from scratch, so compatibility issues may occur. The emulator supports disk images saved in the following formats: ATR, DCM, ATX and PRO. You can also make use of Atari (.obx/.xex) executable files.
