Basilisk II Disk Image Chooser

Basilisk II Disk Image Chooser is part of the Basilisk II ecosystem, where the primary application (Basilisk II itself) has received updates as recently as version 0.22 of the Basilisk II GUI, which was released in late 2023. The search results specifically confirm that the Basilisk II GUI is a Universal Binary that runs natively on both Intel and Apple Silicon Macs. While the Disk Image Chooser is a companion utility, you should check the E-Maculation forum and downloads page to confirm whether the latest version of the Disk Image Chooser itself has been updated to a native build alongside the main Basilisk II GUI. If it remains Intel-only, contact the developer (emendelson or the E-Maculation community) to ask about native Apple Silicon support before September 2028, when Apple removes Rosetta 2 from macOS 28. The Basilisk II GUI at https://www.emaculation.com/basilisk/ is actively maintained and ships as a Universal Binary, so updating that component is your primary path forward.
