I tried this and it says it patched it successfully ...but no changed occur. I tried a saved game and then i started a new game and both the same results. All i do is change the cost of the satellite to 1 and then go try to buy and its still 100. Easiest test, edit XEW/Config/DefaultGameCore.ini, line 104 is the line for Frag Grenades, change iDamage from 3->9, save the file. Launch XCOM, start new game, try throw the grenade. And no unfortunately the tool does not work with "alternative" version because unfortunately the "alternative" version seems to not work if you alter anything in the executable.
