I borrowed a 1920x1200 monitor and tested the 1920x1200 version of my patch, and it works like a charm! Omg, what a huge view!

I'll publish the latest binary and the sources a bit later on!
The 1440x900 version, by the way, doesn't work flawlessly yet: apparently I've only found/marked the 1280x1024 map and other UI positions, and 1440x900 is a patch for the 1024x768 resolution.... (because 1) I didn't write code to SHRINK images yet, and 2) the minimap in x768 is a bit smaller, so by using the 1280x1024 one, you'd lose precious screen height.
Example resolution map:
1024x600 (netbook) is patch for 800x600 (should work already I guess, it's the easiest since no GUI positions need adjustment)
1280x720 is patch for either 800x600 or 1024x768 ? both don't work well yet, the latter can't be done yet because the code can't shrink gui images.
1280x768 is patch for 1024x768 (should work fine)
1280x800 is patch for 1024x768 (doesn't work well yet)
1366x768 is patch for 1024x768 (should work fine)
1440x900 is patch for 1024x768 (doesn't work well yet)
1600x900 is patch for 1024x768 (doesn't work well yet)
1650x1080 and higher are patch for 1280x1024 (so far seems to work)
ATM, the app takes a resolution as cmd line parameter, and automatically finds the highest resolution that is smaller (in both dimensions) than the requested one, and patch that resolution. It outputs an executable named e.g. age2x_1_1680x1050.exe and a patched interfac.drs named e.g. 16801050.drs in the Data folder. The exe refers to this drs file.
