All Hugi issues since #11 (and even some before that) have had a bonus pack to them. Such a bonus pack primarily consists of source codes related to the programming articles of the respective issue. Some packs were included in the issue's main archive, while others were distributed separately because of their large size (after all, they are only interesting to coders). In case you're looking for a particular bonus pack and can't find it inside the archive of the issue, or if you're only interested in the pack and don't want to download the full issue, or for whatever else reason, here are all bonus packs since Hugi #11 for download:
