i've found this syntax to AmigaImpact posted by Batteman 10 years ago, thanks Batteman!

python2.5 -O main.pyo –r r.0.0.mcr -x 5 -z 5

So you need to install Python 2.5 before, and i have realized a "cd partition:minetest/ before.

Here a window 'Test' is open and i have "application is mediating"... (on Powerbook and G5)

Maybe it work on a Mac mini ?

I have tried with a stack but without success...

Any ideas ?
