Thank you!

I personally don't have neither C64 datasette nor cassettes. So, if someone has it and able to add support, then welcome.
MiSTer C64 core supports TAP file loading by imitating cassette loading which excludes use very old and hard to find media.
C64 core also supports disk writes which was a preferred way to save the date back in the day of C64 era.

P.S.: I have real C64 but tape/datasette i left in the pass forever :)
