Certain Yamaha samplers (such as the TX16W) used floppy disk drives to store their data. The disk format ("MSX-DOS") was almost DOS/TOS-like, but a few minor differences gave TOS a really hard time to understand the format:

• Filenames with blanks
• FAT backup copy missing

This small program patches those problems away, making the disks TOS-compatible.

Hmmm... after all these years, it occurs to me that "MSX-DOS" might actually be the same DOS format as it was used for MSX computers. Not too unlikely, in fact, since Yamaha was one of the promoters of that homecomputer standard. Also, Microsoft played an key role in this initiative, and it's reasonable to assume that they would use a DOS-compatible disk format. Can anybody confirm this hypothesis?

Yamaha Protector

Those Yamaha sampler disks also had an interesting protection scheme on them. If I remember correctly, only protected disks were accepted by the Yamaha sampler, so you couldn't simply format a floppy disk using a DOS or TOS box and just use it on the sampler.

Yamaha Protector installs the protection scheme on unprotected floppy disks, and it can remove the protection from protected media.

I still have the source code, but I'm not sure whether I ever completed it. If anybody has the means to test it, let me know (simply use the comment box).
