Is it possible for you to publish a kind of Gamestudio Legacy Model Pack which contains the mdl files from A4-A6?

I don't know if your license agreement with the artists allows you to do so, but it would be an easy way give some models to the community.

Yes, those models are as old as the mentioned prefabs - but this would be an optional download for those who are in need of some sample models.

You can find all the models from A4-A7 on the official 3D Gamestudio downloads page.

That includes all the familiar models, like:
Inmate
Hero
Cbabe
Pguard
Witch
Warlock
Soldier

And other models from some of the old example games, like Adeptus, Triplane, Mission, and Mission 2

Yes, but it seems you need a password to download the games.zip
If you use the free A7 version you cannot download this old package.

The levels would not run with A7 anyway.
I thought it would be a good idea to give those old models to the community for free as a single download only containing the model files.

This would be an easy start without much confusion.

You can download all old packages with the free version.
