Is it? I thought it was kept along with the seek tool data. It can't be in the fids directory as that's read only when not syncing.

Yeah, you're right. I forgot that the per-FID data is stored on the dyndata partition for all fids, starting at 0x200. The running order area of the partition is after the playlists portion and just contains entries for the current running order.

Tom, I could probably whip something up that would give you what you want (the fids of marked tracks on the player) pretty quickly.. Just let me know how you want me to format the output.
