So, here is what I did:
I put all files on my MMC and I pub freera exec in my home and I created this file:
#! bin/sh
cd /media/mmc2/Games/freera++
exec /home/user/freera

but that didn't work and it says:
ERROR: Unable to open freecnc.ini

So, I tried to make a symlink doing this in my /home/user :
ln -s /media/mmc2/Games/freera/freera++ freera-launcher
and then :
./freera-launcher
-sh : ./freera-launcher: Permission denied
but, freera-launcher have 777 chmod :s
