SAMdiskHelper is a helper Windows service, providing access to BDOS (Atom and Trinity) and Pro-DOS format disks from normal (non-elevated) applications.
SAMdisk and SimCoupe builds from May 2016 require at least SAMdiskHelper v1.3 to work correctly.
Version 1.3, last updated 17th May 2016 [view ChangeLog].
SAMdiskHelper v1.3 (160K).
SAMdiskHelper will be used automatically if disk devices can’t be opened directly.
