You need a Hex editor for this, I used Notepad++ and its the best one I believe, download Notepad++ from here[notepad-plus-plus.org] you also need the HexEditor plugin, to get it open Notepad++ and click Plugins > Plugin Manager > Show Plugin Manager and find HexEditor, click on it, install it and tick it, then close the manager.

First off go to your game directory in Steam/Steamapps/common/toy soldiers folder, and make a copy/backup somewhere of GameSW.exe incase something goes wrong ( note that this is the exe of the non-Games for Windows Live version, so DON'T select the second Games for Windows live option when you start the game )


1. After you've made the backup, you need to open GameSW.exe with Notepad++, one way to do this is to open Notepad++, click File > Open and browse to GameSW.exe in the game's folder
2. Once its opened you should see a bunch of gibberish, click on Plugins > Hex-Editor and tick "View in HEX"
3. After you've done this, you need to scroll down on the "Address" column and find the values 00003ad0 and 00003ae0, both are next to each other

4. Now you need to edit the values which are highlighted in blue on the screenshot (38 04 and 80 07) like so (though I'm just editing random values to show how its done)

38 04 represents resolution height and 80 07 represents the width, use this chart[pastebin.com] to figure out what to change it to for your resolution's width and height (note that capital letters will always change to non-capital and thats fine)
Example: If I wanted 1440x900 resolution, I would change 38 04 to 84 03 (because that's the value for 900) and 80 07 to A0 05 (because that's the value for 1440), like so (these values are only for 1440x900 )

5. After you've changed those values to your desired resolution, just click the floppy save icon on the top-left, and exit the program.
6. Launch the game ( without games for windows live ), and on video options scroll around, there should be a new option for your new custom resolution.
