Doesn't work. I just end up with a black screen, but I can see my mouse. It's clearly still in the small resolution. Also RA2.ini doesn't even exist. It's RA2MD.ini for me.
Edit: I just downloaded the RA2 from XWIS, and RA2.ini does exist. But this fix still doesn't work for Yuri's Revenge.
The fix i posted dont work on XWIS version.Only original and origin versions.
