Thanks for letting me know, I don't check the Google Code issues often because hardly anybody uses them, so I only responded there because I read this topic. If you need help with compiling the game feel free to ask

I tried again and after some tries I managed to compile (and run) the project. Somehow I miss the file guimainh.rx (it is not in my KaM TPR directory) so I could not generate the sprites. Luckily, I managed to get the generated sprites from the installed KAM Remake version (the official version from the website).
Moreover, I did not use the HEAD-revision, because a few commits ago someone added an option screen to the Map Editor and this is not included yet in the Lazarus project if I am correct. Now I use rev. 6580, just before that happened.
Everything now works fine, except that the "Options" in my Main Manu still fire a Range Check error. I think this is because of the missing sprites, but I will debug that later. For now, it works and I am going to enjoy my sunday

This weak I am going to study the code and try some changes here and there. Maybe I can help you with a few changes in the near future. Luckily my coding skills are better than my KaM skills
One compliment should be made here. Although the project currently is quite large and works pretty well, somehow you managed to keep the code quite clean and readable without adding too much comments. I opened some AI-code and could easily read and understand what you were doing there which is quite cool.
