This ROM dump comes from the A1200’s 37.350 (early beta) or the final 39.106 revision. The latter is considered the gold standard for compatibility with WHDLoad games, demos, and boxed software from 1993‑1995.
Important legal note: This file is still copyrighted by Cloanto (who acquired Amiga IP rights) and original authors (Commodore/Hyperion). You must legally own an Amiga 1200 to use this ROM dump. Pre‑configured downloads of this file are illegal. Scrape your own from a real machine using tools like GrabKick or TransROM, or buy the Amiga Forever package which includes licensed ROMs.
In emulation (WinUAE):
On real hardware:
This is the most common modern use case. To emulate an Amiga 1200 cycle-accurately, the emulator requires a binary image of the ROM. Amiga-os-300-a1200.rom
The "300" in the filename refers to AmigaOS 3.0. For the A1200, this usually corresponds to Kickstart version 39.106. This operating system introduced features that are still praised by enthusiasts today:
File Name: Amiga-os-300-a1200.rom
Type: Kickstart ROM (Firmware)
Version: Amiga OS 3.0 (Kickstart 39.106)
Target Hardware: Commodore Amiga 1200

As the original A1200 hardware approaches its 35th anniversary, the physical ROM chips are degrading. The bits stored in those Mask ROMs are fading. Projects like the "Amiga ROM Replacement" (ARR) and "Kickstart Switchers" allow users to load Amiga-os-300-a1200.rom from modern flash memory.
Furthermore, the open-source "Aros" (Amiga Research Operating System) has created a replacement ROM, but for 100% compatibility with classic AGA games, nothing beats the original 3.0 binary. In emulation (WinUAE):
If you see the red "Software Failure" screen (Guru Meditation) immediately upon powering up with the ROM, it is not the ROM's fault. This indicates the CPU, using the valid ROM, tried to read a corrupted floppy disk or an incompatible accelerator card.
