Atari ST Public Floppy Database now open for everyone — online archive originally designed for ST flash cart packed with classics and homebrew

An extensive Atari ST floppy disk database has become accessible to all netizens, originally designed for users of the SidecarTridge multi-function hardware add-on for the Atari ST family. This includes computers such as the ST, STE, Mega ST, TT, and Falcon. The database, created by the SidecarTridge Multi-device, allows users to browse, search, and download .ST files for use with other hardware, emulators, or to rewrite the disk images to actual floppies.

Until now, accessing this community-curated archive of floppy images required using an Atari ST with a SidecarTridge Multi-device. However, the online repository is now open to everyone. Among the available titles are classic platformers like Turrican and Turrican II, public domain/shareware favorites like Gravity Force, and Llamatron.

Although some expected items, such as the Stupendous Demo and certain DTP tools, are absent, the database is regularly maintained and updated with new additions. For instance, there are 41 Atari ST disks flagged as recent arrivals, comprising both older releases and newer titles like homebrew games and demos from the Sommerhack 2026 event.

Originally developed for direct hardware access to provide modern conveniences for Atari ST users, the SidecarTridge device slots into the computer's cartridge port and offers features beyond a simple floppy loader. It can load different ROMs, including the entire Atari ST OS and GEM desktop, via its microSD card slot, provide hard disk emulation, networking features via Wi-Fi, access to an RTC, and support for modern peripherals such as keyboards and mice.
