Well a quick and dirty trick makes it to launch after last situation.
First of all, I copied bitmap.pak from /bitmap/bitmap.apk to root folder (where berusky3D.ini is) and another error like before appears, another .pak not found, I copied again to the root, hence, another one...
I opened berusky3d.ini and find for the apk files and they were pointing to weird places! Then I realized that there was a file called berusk3d-local.ini...

So I renamed to berusky3d.ini and start the game... with no problem

I cannot test the game itself (coffe time at work) but when I'm in home I can tell you if it works nice on there.
