Version 4.3 binaries of the DC2N4-LC multi-threaded GUI client were published within my Software page.
Within the same Software page I also published version 1.1 binaries of my filename extractors.
I also wrote a gist that uses the CBM ROM filename extractor in order to append the name of the first CBM ROM file found in each TAP file to the TAP filename itself. It requires a bash equivalent under Windows. If you have Git installed, you can use Git Bash.
