The v2025.01.09 release contains a new RP2040/2350-specific beta-quality feature that allows you to use your modern computer along with a USB-attached ZuluSCSI RP2040 as a USB SCSI controller, enabling you to read and write to SCSI block devices as if they were USB hard drives. Throughput is limited to approximately 768 kilobytes/second, best case, which is a hardware-level limitation of the USB 1.1 controller in the RP2040. Not all variants of ZuluSCSI RP2040 support initiator mode. See the list below.

• For all red ZuluSCSI RP2040-based boards, simply copy ZuluSCSI_RP2040_2025-02-05.bin to the SD card you normally use with your ZuluSCSI, and then re-insert the SD card and power it on, at which point it will detect the .bin file, self-update, and then remove it and reboot, running the latest firmware.

Initiator-capable ZuluSCSI models

• All Full-size ZuluSCSI RP2040 boards
• ZuluSCSI Pico OSHW (Full Size)
• ZuluSCSI Pico (OSHW) Full-size (desktop) board
• ZuluSCSI Compact RP2040 Rev 2023b
• ZuluSCSI Compact Homebrew Rev 2023b

Just a quick note, the link in the instructions names and points to the previous version.

Thanks, I fixed this yesterday. I also made a new release today, and verified it's correct there :)
