This video shows you how to create a script file, tag it with an icon and make it executable in IRIX.
Take not of the fact that in this video I used: su root -c "/usr/nekoware/games/quake3/quake3" and that sometimes you will have to use separate lines as such, to get the script to work properly:
cd /usr/nekoware/games/hexen2
./hexen2 -width 1920 -height 1080
