No, I'm not confusing ZHLT and Hammer. I'm showing you how to customize Hammer's appearance a little. I take no responsibility for anything on the face of the earth ever blah blah blah blah.
Okay, here're a few replacement splash screens I cobbled together for the purposes of this demonstration. I will show you how to take this image and put it into HAMMER.EXE, so I recommend backing up the original program file before beginning. Now you need to get a little program called "ResHacker". You can get that here and it's about half a meg.
Once you have ResHacker, just open the ZIP and run the program. It creates no registry entries so uninstallation is simply a case of deleting the files if they are present. Leave it open while you follow the next step.
Now, I want you to take the replacement splash screen and save it somewhere as a Bitmap (extension '.BMP'). You can do this in the versions of Paint that come with later version of Windows, or with the excellent freeware tool Irfanview.
Once you've done this, go back to ResHacker. Click File -> Open and then browse to Hammer.exe. Some jargon and odd numbers will appear in the left-hand pane. Click the "+" next to "Bitmap" and a submenu will unfurl. Then find "172" in this new menu and click the plus sign next to that. A screenshot is provided if you're confused [clicky].
Now click on the "1033" under "172". It's the only option. Look! The original splash! Right-click "1033". A menu will show; click "Replace Resource". A dialog box will now appear. Select your new splash by clicking the appropriately-titled button at the top-left. When you've selected the splash, click "Replace". Then just click File -> Save.
Open Hammer and bask in its beauty.
Look at all the other places in Hammer. You can replace the bitmaps for the toolbar buttons, you can even change menu texts. Don't be afraid to experiment. Remember that even if worst comes to worst, you can just re-download Hammer and it'll be fine.
You could try it with other programs too - just remember to back it up!
