Ultimate64 Manager, a desktop application for controlling Ultimate64 and Ultimate-II+ devices, has been updated. The music player has been completely rebuilt with full playlist support, including save and load functionality, shuffle and repeat modes, subsong navigation, and automatic song length detection using the HVSC Song lengths database. An "Add All" button allows quickly adding entire folders of SID files to the playlist.
A new streaming feature enables sending local files directly to the Ultimate64 without needing to upload them first.
The configuration editor is another addition, allowing users to view and modify all device settings, save configuration to flash, load from flash, or reset to factory defaults.
The remote file browser now supports mounting disk images directly from the interface, including D64, G64, D71, G71, and D81 formats, with options for read-only or read-write access. Password-protected devices are now fully supported across all features. This release also includes various bug fixes and stability improvements. Ultimate64 Manager is free, open-source, and available for Windows, macOS, and Linux.
