I've done some more work on SaveROM. The list of changes:

• full MSX-DOS2 support, which allows saving to FAT16 drives, and use sub-directories
• fixed a bug causing dumping megarom 00-FF range to get in an infinite loop
• megaROM question has become a type select
• added memory overview of pages containing something
• added display for megarom block number as a progress indicator

Thanks go to Patriek Lesparre for improvement ideas.
