Check this forum, there is a section where I give links to the files needed etc.
EDIT:
Since I sense you are probably impatient here you go..
Ok here is a step by step on actually how to edit the .ini file safely, no matter how many extra characters or lines are used.
1. Download Notepad++
Link - Never EVER use normal Notepad, Wordpad or Word to edit the ini file.
2. Download Ruby and I included a ruby script to fix the CRC of the .ini file after editing.
Link3. Install Notepad++ and Ruby (which is in the .rar file)
4. Copy the included .rb file, to your C:\Program Files (x86)\Mass Effect 2\BioGame\Config\PC\Cooked (or whever you installed it) and paste it in here, so that you only have the .ini file and .rb file there.
5. Make a backup of your original unaltered coalesced.ini file. And open with Notepad++ make your changes.. And no dont AllowD3D10use when you see the option, as its not fully supported.
6. When done making changes, save, and then open up the .rb file. It may or may not have associated the file type, if not find ruby.exe (not rubyw.exe) where you installed it and tick always open up this file type with this program. It will then scan the ini file and make a fixed - coalesced.ini file. Delete your amended file you did and rename the new one by removing the "fixed - " and thats it.
Hope you understand.
