Boot menu for C64 Ultimate-enabled devices, with auto-boot default slot and mount/command-only slots.

Boot menu for Commodore 64 devices equipped with an Ultimate II+ cartridge. Version 2 is a full rebuild using the Oscar64 C compiler, replacing the earlier CC65-based version.

Version 2.1.0 adds a default boot slot with a configurable auto-boot timeout (great for auto-mounting a disk on power-on), and menu slots that only mount a disk and/or run a command without launching a program.
