Castle have issued a new RISC OS 5 ROM for brave Iyonix users to beta test. Version 5.10 is mainly a bug fixing exercise, and coincides with a USB mass storage update that also corrects a few glitches. “It is intended that these updates will go in general circulation in a few days time, unless anything hugely untoward crops up. We have been running these for a while now,” said Castle’s John Ballance. This update also includes the updated GeForce 2 driver, bringing 3D acceleration to RISC OS.
