If you have any errors, please do let me know in this post what the problem is and if possible, if you could upload the saved game you are using that XCOMHACK is not friendly with, it would be greatly appreciated. Please report any other problems with it here as well.
It is only for XCOM UFO right now, you can point it to ufo.exe for the CE version, or the geoscape/tactical.exe for the DOS versions, either will work. Thanks ahead of time for your help.
