I'm pleased to announce the release of the version 4.0 firmware update for U1MB, Incognito, SIDE2, SIDE3, 1088XEL, and 1088XLD. The update includes a redesigned SIDE loader, and completely redesigned BIOS plugins with support for SIDE3, Sophia 2, and PokeyMAX. Also newly introduced is support for an NTSC colour palette in VBXE (loaded transparently when the machine is turned on). User documentation has also been comprehensively updated, with sections covering the new SIDE3 loader and Incognito.
