Battlezone 1

I have been trying to find where are those flags that you may select when you play.
I could not find them. I wonder if there is any way to add my custom flag.

The default flags are all in bzone.zfs. To use a custom flag in BZ, all you have to do is open MS Paint and make a 64x32 bitmap using only black and white. When you're done, save it as flag####.bmp, but not just any kind of bitmap, you have to save it as Monochrome bitmap from the drop-down list. I simply saved my flag as flag0000.bmp. If you save it as flag0010.bmp, it will replace the default "angry face" flag.

Where do I save the file?
In the same directory of bzone.zfs?

Oops, I knew I was forgetting something, just wasn't sure what it was. Custom flags go in the addon folder.
