Habe nochmals gesucht und folgendes gefunden. Ich glaub mich erinnern zu können, dies auch bei dem ersten Link so vorgefunden zu haben.
100% gamepad support in all menus, including force feedback for the xbox 360 controller. All buttons should now be properly mapped (same as on the xbox 360 version).
Backup your original ini files/save games and replace the ini files located in .../My Documents/BioWare/Mass Effect/Config/ folder with these.
The mouse is only needed to:
*use the tactic hud
*select a weapon upgrade
I've only made some minor changes to the previous 1.0 version:
*Added the 360 achievements menu (but using the PC handler, so there shouldn't be any problems).
*Remapped Galaxy Map cursor to Left Stick
*Mapped the Right Thumstick to switch weapon
