DOS never did this %..% variable substitution in the interactive command line. It was only available in batch files, and the FOR command. This is unlike NT's and 4DOS, I believe.

You can trivially do 4K Windows 9x (and more) under VirtualBox with the open driver @ https://www.os2museum.com/wp/windows-9x-video-minidriver-hd/ Just edit the .inf file before installation to add the resolutions you'd like, as the author recommends on the blog post. Or after installation change …

Now I am wondering how difficult it would be to nominally do mouse integration for Win9X.. that would be awesome to have! I might have to look into it if someone isn't already working on it! This already works as-is for 9x, you just have to install it manually , i.e. by loading VBMOUSE in autoexec. …

I don't think you want a redirector, rather you really want a device driver so that DOS can mount your USB disk and handle filesystems for you. It'll be simpler than a redirector, even! Note that a device driver .sys file can be loaded at runtime using any of the popular DEVLOAD equivalents. It is …

actually its the opposite. With WDM drivers (aka sbemul.sys) , there is emulated mpu401 device which is redirected to whatever you select in the midi mapper, and there is absolutely no adlib/fm emulation (sbemul only emulates the opl timers but generates no sound).
