DiscMedic

Use at your own risk, this has had 6 months of internal testing, but it may not be production ready for FileCore. UFS2 was originally our target, but if you get any issues there is a rollback option within the app to undo any changes it may break. Please feed back any bugs to the website’s private developer bug tracker. We as a team want to make our software better.

Notice: DiscMedic was originally developed for the 64-bit platform, as we needed a tool to support UFS2 and the current disc-tool market had stated that they wouldn’t support an OS that had been created with the help of AI. We also understand the fear and concern surrounding AI, and therefore we believe in user choice.

Version 0.11111 KB ZIPReleased 22 October 2026

A disc checking and repair utility for RISC OS 5 or later, with a desktop interface and command-line engine. Checks FileCore new-map and FAT12/16/32 volumes on hard discs, SD cards, NVMe and USB drives.

Choose a quick check of the map and tables, a full file and directory check, or a detailed report. Includes repair with undo files, report saving, boot-partition inspection and CMOS backup and restore.

Unpack the archive and run !DiscMedic. Read the supplied ReadMe, Help and Limits before use. Start with a check, back up important data before repair, and keep the undo file on another drive.

Bluetooth for RISC OS

New in 1.01: Adds BCM4345C5 firmware and updates the BTVoice module.

New in 1.00: A redesigned Devices window shows individual device cards with clearer pairing and connection controls. Scan, Settings and Help are easier to reach, and BTReport is available for diagnostics. Pinebook Pro’s built-in Bluetooth remains supported.

New in 0.96: Fixes an NVMe failure on Pinebook Pro and boot issues on CM4. Pinebook Pro uses its built-in Bluetooth.

New in 0.94: Now supports the Pinebook Pro’s internal Bluetooth. Support for the TP-Link UB4A dongles introduced in 0.93 is retained.

New in 0.93: Now supports the UB4A dongles sold at the London Show, as someone brought the wrong ones… cough, Andrew! :)

*Notice: The tested Bluetooth dongles are the UB400 and, from version 0.93, the UB4A from TP-Link. The 1.01 ReadMe reports testing on a CM4 with RISC OS 5.31. The Pinebook Pro uses its built-in Bluetooth. Support for i.MX6 is still being developed. During testing, I found that several dongles sold as CSR8510 devices were cheaper variants and were not always genuine. Yes, shocker — fake ones exist! I recommend buying a dongle with a genuine chip.

Iris Frosted

Version 1.039v2Updated 26 May 2026

The !Iris web browser in Frosted style, with a new user agent. Version 1.039v2 updates the banner and interface. Two packages were published; they differ only in how the !IrisRAM launcher is arranged, so either will do. Iris is a port of WebKit 2.40.5, so it handles JavaScript and HTML 5 over TLS.
