I'm also 1.02 retail (from when the game originally came out).
I can get everything to work normally at 2560x1600. And when I run Widescreen fixer (r376.7z) everything still works "normal". WSF recognizes the game is running, says fix is enabled, but still on 1 screen.
So then I went into ME ini file and manually increased resolution to 7680x1600. And the game will still load and run perfectly, but everything is obviously very zoomed in (no FOX fix). Alt-Tabing out shows me that WSF thinks it is running, but nothing is happening.
I guess this is because I have the retail version, and not Steam. is there anything that can be done that I could help with? I don't know very much about hex edited, etc.
If I had a steam version, would I still need to go into the ini and increase the resolution manually, but the fix would just fix FOV for me?
I've found a workaround that will make all versions of Mass Effect (including Origin and Retail) work with helifax's Plugin.
Firstly, if you have any DLCs installed for your copy of Mass Effect, you should do a clean re-install.
Download 'Bring Down the Sky' and 'Pinnacle Station' DLCs from Steam and install them.
This will not only install the additional content but while doing so overwrite the executable with a Steam 1.02 version.
Then simply use helifax's Plugin :)
ps. @helifax: it's a great Plugin, but I noticed the 'lock-on' reticule (when talking to people or activating doors)
is not placed correctly. Is this being worked on? or maybe this is a side-effect of the workaround.
