Petition of tutorial about how to mod unitbox.bmp

[Kuriltai]

I use MS paint.
Make your new background the proper size.Inside the unitbox lines is 176x114 or there abouts.
Open a unitbox.bmp.
Use "edit" then "paste from" and put your new background in on both sides.
Adding the nationality flag or roundel can be on the unitbox itself or from the 2dsymbolslg.bmp
Save as whatever you want to call it.
Send me a email if you have trouble.
