About a month ago Marcos Daniel released Final Copy, one of the best MSX disk copiers ever. Supporting only Brazilian disk interfaces (port-based), this program can create backups of virtually any type of disk (including 360k and 720k 5 1/4" disks), including a lot of sector-based copyprotections and restoring CRC errors. As sources are included you are free to add support for other MSX diskinterfaces. You can download Final Copy here.
Currently, our downloads database contains more than 500 freeware downloads. If you'd like to share your productions with the MSX community, send them to downloads@msx.org. Happy downloading!
