I decide to install Preenv 0.1.6 (instead of my previous version 0.1.4) and I put the last version of Jflatt "libsdlpre.so", size 71.9 KB (to play to Galcon, Radiant and Buka). But I discovered an antialiasing issue on Angry Birds (normal and Seasons version).Is this behaviour is normal from the last library ?.
But still, they won't be erased until the current breakages in preenv 0.1.6 get fixed.
