Due to some annoying incompatibilty issues between different versions of GlibC/GCC, there are now two different versions of r1q2ded, the "normal" one, called r1q2ded, and one designed for loading old gamei386.so files, called r1q2ded-old. At present I would guess that most people are using r1q2ded with old gamei386.so files as b1258 seems widely deployed and unfortunately that was built with support for old gamei386.so files.
It is recommended you download r1q2ded-old
from the R1Q2 page and replace reference in scripts to r1q2ded with r1q2ded-old when upgrading to b1390. Apologies for the switching around but it is necessary to maintain maximum compatibility with old and new mods. Use the following list if you aren't sure which version you should run:
Known mods that require r1q2ded-old:
Jailbreak 2.5, OSP 2.7x, baseq2 DM, Threewave CTF.
