THEA1200 adds Workbench 3.1, WHDLoad, and Amiga model switching

THEA1200 will ship with Workbench 3.1 and let users boot straight into either the desktop or the games carousel. It will also handle WHDLoad, floppy images, hard-drive images and CD-ROM images, which is the difference between a toy menu and something that can actually behave like an Amiga you use.

That matters because Workbench changes the machine’s tone immediately. A built-in desktop gives THEA1200 a proper entry point for configuration, file handling and software compatibility instead of forcing everything through a preloaded game screen. WHDLoad is the bigger unlock for game loading, since it opens the door to a much wider slice of the Amiga library than a fixed set of packaged titles ever could. Retro Games Ltd is also adding USB loading and multi-region HDMI output, so the system is being built around the sort of mixed use that defined the real machine: boot a desktop, load software, switch media, keep going.

The other piece that makes this feel serious is model switching. THEA1200 will be able to move between virtual Amiga 500, Amiga 1200 and CD32 configurations, while Retro Games Ltd says the hardware emulates the original A1200’s AGA chipset plus earlier A500 OCS and ECS modes. That widens the target from one narrow interpretation of the platform to a more useful cross-section of Amiga history. A game that wants an A500 setup, a demo that expects AGA, or a CD32-friendly format no longer has to be treated as a separate problem.

Retro Games Ltd has also packed in a few details that back up the full-machine pitch: an included Workbench installation, 25 preloaded games, four save slots per game, a full-size working keyboard, classic mouse and game controller support, and full WHDLoad support through USB stick loading. The company’s current launch page lists Friday, December 4, 2026, after a May delay in which Chris Smith, Retro Games Ltd’s chief technical officer, said the hardware was complete but the operating system still was not where it needed to be.

That delay now reads as the right call. THEA500 Mini was a smaller, keyboardless box built for quick nostalgia; THEA1200 is being shaped as a full-size Amiga revival machine that can boot Workbench, run owned software, and swap models when the software asks for it. For this corner of retro hardware, that is the line between a display piece and something that starts to earn desk space.
