C128: DMBoot 3.91 new features demo

Demonstration vidieo of some recent features of my DM Boot boot menu.

I am testing now the 3.91 alpha version, which adds the possibity to add mounting predefined disk images to both Ultimate II+ drives and load a predefined REU file for every menu slot in the boot menu.
In this video this enables to start GEOS Megapatch 3.3 128 while automatically mounting two disk images and a REU file, all with the press of a single button in the boot menu.

The video also shows the already existing functionality to start programs via the hyperspeed file system, and to start programs in 64 mode with fastload from 128 mode.

GitHub branch for the new version:

Documentation is not yet updated.
