Alternative to SparkCS.exe console?

[nWo51289]

I'm making a auto installer for my files (which adds up to almost 4GB!) and unfortunately the SparkCS.exe console which I was using gives an error whenever gta3.img goes over 2GB. So was wondering if there is something similar to SparkCS.exe which will be able to add files to gta3.img way over 2GB without giving an error and simply freezing? Thx.
