Version: 4.50

AltirraSDL is Altirra, Avery Lee's very accurate emulator of the Atari
8-bit computers (400/800, 1200XL, 600XL/800XL, 130XE, XEGS and the
5200 console), with an SDL3 and Dear ImGui user interface by ilmenit
and contributors. This is AltirraSDL for MorphOS.

Replacement ROMs are built in (AltirraOS and Altirra BASIC), so no
original Atari ROM images are needed. Disk, program, cassette and
cartridge images are opened from the File menu.

Requirements: MorphOS 3.20+ on a PowerPC G4, and the SDL3 libraries
(3.4.18 or newer): EasyInstall installs them together with AltirraSDL.
Without EasyInstall: install the SDL 3 package from MorphOS Storage
first (https://morphos-storage.net/?find=SDL_3).

Installation: with EasyInstall, or unpack the archive and drag the
AltirraSDL drawer where you want it. Unpack, ready to use.

Double-click in Workbench: not set up by unpacking. Run
Install_Filetype in the AltirraSDL drawer when you want it, or copy the
file type by hand (see ReadMe.txt).

The source code is in AltirraSDL-src-4.50 (GNU GPL).

This is an UNOFFICIAL port, not made or supported by the original
authors. Report problems to the porter.

MorphOS port by Lastic
(lasticppc@gmail.com), made with the help of Claude Code
(Anthropic's AI coding assistant). Tested on a PowerBook G4 15"
1.5 GHz and an iBook G4 12" 1.33 GHz.
