These are all scenarios from Age of Empires DE stock campaigns.
They were extracted with this tool
The work it's 99% from Siege Engineers. I just managed to search and find that tool near the time they were working on updating it in order to work with the DE campaign format.
Notice that this tool DOES NOT extract the AI files that come with each scenario. This also happens with the native Age of Empires II HD native campaign extractor. And my guess is that it also happens with Age II: DE campaign extractor.
This doesn't work either
so AI's for these scenarios will need to be built from scratch.
Now, it seems that Campaign Manager extracts RoR (and AoK) scenarios with their AI's so maybe with some hex editing, the AI's for the scenarios that are the same in RoR and DE can be recovered and may be useful.
Rumor says there is a new DLC incoming. If it's a new expansion with new campaigns it would take a few months for them to modify genie-rs in order to extract the new format that would accompany said new DLC.
Enough people asked me for the scenarios that I decided to ask PhatFish if it would be correct to upload them here
Approved. I doubt the same old original AI files were used but I am sure the ones they used are based on these. I guess one could try and apply them to these DE campaign scenario's and see if they work like you would expect them to.
