Neuwissen

I finally found all the hidden objects. Some of them were really hard to find, so I made some maps (by districts) with the locations where I found them. This way, I'll find 'em all again in future plays. I would like to post them but I don't know how to do it yet. If anybody could help me....

Is there anywhere a list of the contents of "gta3.img" with an explanation about the uses of each one? If someone knows of any, please tell me where can I find it/them.
