Command and Conquer Generals Resolution Refuses to Change

@Hoppycactus 

Do realize that there's a huge difference between playing RA2 in high resolution and playing Generals in high resolution.

• In RA2, the larger your resolution, the more viewport you get in-game, and the more your units look like ants.
• In Generals, the larger your resolution, the more you see how low-poly the models are.

Honestly, I don't understand people's obsession with trying to force games into resolutions they were never made for. Case in point, in C&C1, The maximum map size is only 1488x1488, so playing on 1920x1080 would always give problems.

That all said... I'm not sure how you can't do it in RA2; it's literally just editing the ini file in the game folder.

For the rest...

Command & Conquer 1, Red Alert 1 and Tiberian Sun have all been upgraded with community-created unofficial patches that fix a lot of their bugs and compatibility problems. For Red Alert 2, Generals and Renegade there are some more general patches that solve a bunch of their problems. You can find them here:

Command & Conquer 1:

• Nyerguds' C&C95 v1.06c revision 3 patch (which also adds bonus missions originally exclusive to the Playstation and Nintendo 64 versions of the game)
  Note that this patch fixes two quite common and completely fatal game crashes (top-of-map reconnaissance crash, stealth crash), so installing it is strongly advised.
• An upgrade for the patch's config tool and cnc-ddraw component have been provided by FunkyFr3sh. Apply it after installing the patch.

Red Alert 1:

• Funkyfr3sh's automatic Red Alert 1 patcher/installer (The thread also has briefing videos for the expansion missions, converted from the Playstation version of the game)
• Nyerguds' main.mix cleanup for TFD/TUC (Not really needed, but cleans up about a gigabyte of unnecessary files in the RA1 folder. Unpack in the game folder, run "patch_main.bat", let it finish, and then delete the files you extracted.)

Tiberian Sun:

• Funkyfr3sh's Tiberian Sun patch

Red Alert 2:

• I advise installing the CnCNet online play installer for RA2/YR. Even if you're not interested in online play, it comes with a bunch of automatic fixes, and has a configuration tool which offers multiple choices in graphics output libraries, so if one doesn't work you can just try if some of the other options do the trick. Said tool most likely includes resolution stuff too.

Generals:

• GenTool seems to be the main patch for Generals these days. The website is kind of vague on what it does besides restoring multiplayer and adding anti-cheat, but I heard it does a lot to make it work better on modern OSes too.

Renegade:

• Kind of like the Generals one, I don't really know the specifics on this, but the Tiberian Technologies patch seems to be where most of the Renegade patching is done.
