A: You don't. The beauty of 3.8 is that it is a pure 2012/13 patch. To get modern transfers, you would need a different patch like "PES 2013 Smoke Patch" (X.20 version), but that lacks the polish of PESEdit.
The primary reason people download this patch is to update the rosters. PESEdit 3.8 successfully brings the squads up to date (relative to the time of the patch's release). pesedit 3.8 pes 2013
