WsDos v7.1 by Sid Davis, released early 2018.  Although the documentation describes this as a loader for C64 software using native C128 burst mode, it does so much more!  Below is a quote of the description and features from the docs:

WsDos is a program for the Commodore 128 PC. It provides a way to load and run C64-mode software using the C128's native burst mode protocol. This is done by loading a program while in 128-mode, then switching down to 64-mode where it is started.

 Installing itself into a seperate bank of memory, the program is protected from being overwritten while in 64 mode. It is also invisible to a suprising amount of C128 software as well. It even survives a CP/M session!
