I am just about finished with a Discus 4.0 to SMF 2.0 converter. It is mostly a manual procedure (phpMyAdmin Importing to SMF database) but it gets the job done. It is written in VB6 and you will need to download some of your board to make the conversion, but hey "You don't have any other options" Yes, I checked ;D. I will give complete instructions on the process. The instruction will tell you which files and folders to download (FTP) and which files not to download (since the converter will not do attachments as of yet). (https://www.google.com/) If you are interested in the converter just let me know and I will make it available for you to test with your Discus board.
