The misterfs program is the easiest way to transfer files from your PC onto the AO486 core in MiSTer. You basically move files onto a folder in the AO486 directory and they will automatically appear in DOS. The video shows just how easy it is to use the software.
To get the misterfs program onto you AO486 DOS install, you will want to create a floppy image of the file or a VHD. Below are links to videos showing you how to do that.
