BTW, I am planning to try to get a few AOK Mods to work on AOK HD, the Steam version. Supposedly Genie Converter is able to do this, but it looks complicated.
I am referring to the Rome at War Mod, the Dark Age Mod, and the Roman Conquest of Germania Mod. They can all be found in the Heaven Games Blacksmith, such as here:

With the AOKHD Steam version, things are more straightforward and you can just press subscribe to make a Mod work.

That makes sense.

@rakovsky yes, AOEII HD already have an aqueduct building as you can see in the images, so this mod replaces their graphics with the ones from the aqueduct of AOEII DE.

I don't quite understand how this works. Did AOEII HD come with an Aqueduct building and this mod replaceces it with a AOE II DE version?

@JulioRaider, yes, I could, but if you wish you can also just delete the last two SLPs that are the aqueduct and their shadows. Just let me know what do you prefer.

@Szaladon, I used SLX Studio and Turtle Pack, although I had to fix the shadows by myself manually.

Amazing! Could you please make one without the Aqueduct? Just the Amphitheatre and the Colosseum.

Looks great! How did you convert the graphic files to SLPs?
