FAST!DiskROM extension for openMSX

sd_snatcher has just published an XML extension to allow openMSX to use the A&L's FAST!DiskROM v1.1. This is is a new and very optimized DiskROM for CDX-2 standard floppydisk interfaces created by Adriano. It features a lot of improvements over the standard DiskBIOS:

• The very efficient disk-buffer handling allows MSX-BASIC to always have 25.4KB free, independently of the number of drives connected.
• Highly optimized FDC access routines. Up to 20KB/s transfer rate. The standard MSX diskBIOS only reaches 10KB/s, and the CDX-2 interfaces original BIOS only make 5KB/s.
• 100% compatible with MSX-DOS2 (all CDX2-based interfaces had compatibility problems with MSX-DOS2)
• Supports up to four diskdrives connected to the same interface (DS0 to DS3 drive selection signal is fully implemented)
• Drive letters are dynamically assigned. So it doesn't matter if you have a single drive installed to the system set as DS1, like the PC's default configuration.
• New CALL command added: CALL CHKDSK. As the name suggests, it checks the disk integrity and mark all bad sectors.
• Supports formating disks in interleave 1:1 or 1:2
• Simulated Clock for MSX1 machines
