Important features of this firmware revision:

• File viewer (great for reading the VERSION.NFO files reformatted by the GameBase 64 Reorganizer)
• Integrated SID player
• All fixes and compatible features up to official firmware release 2.6d.

My changes and additions:

1. Added F3 help screen to show 1541U commands.
2. Modified the file viewer so that scrolling will not advance past the last line.
3. Added F1 and F7 page up/down to the file viewer.
4. Modified behavior of the file browser so that when you cursor-right on an item with no children, the context menu is brought up as if you pressed return.
