If you were present at the 2004 Nintendo DS Developer's Conference, you got this for free: an evaluation version of OPTPiX's image editing and optimization software. The disc is marked 'not for sale' and 'full trial / evaluation copy'. The disc has two install options: a limited trial and a full trial, the latter of which requires a USB dongle you also received at the conference. I've got the dongle around here somewhere; I'm planning to check its protocol later. https://mega.nz/#!UMYFiZSa!YvRwTBChXvEPjqNp_WTuPB6mRkUJQJ19RQ2i8a7pr2c The update history file suggests this is an evaluation of version 5.59, released August 26th, 2004.
