Question

Where can I find open source game code on Habr? Several years ago, I saw in one of the threads how users were sharing files with uncompiled game source code. I’ve been trying to find this material for several hours without success. Does anyone know where I can find such resources? Or will I have to continue browsing through all the topics manually? I remember there were simple and old games that I wanted to study and analyze, but at that time I didn’t have time for it. Now I’m ready to study, but I can’t find these materials anymore.
