Thanks SilverWarior. I got to have a look at those engines. I just spawned a new Virtual Machine for the purpose. Noticed a new Lazarus version recently arrived. Though seems to be mostly smaller adjustments this time. But that's the easy part. The tricky thing will be to try out those physics engines.

Meanwhile I will make an other attempt to handle the physics myself in the upcoming heavily physcis based game, or program. If it ever gets done of course. It's easy to talk about games to do but then really finishing them is a totally other matter. And I haven't even started yet..
