Hi there ChezJfrey! Hope you're doing well buddy.

I am not able to start Gof when I try to run it
it always appears an error message asking to check the INI files or scripts, can you help me?

You will get that error if you launch Maelstrom.exe and it does not know where the start.ini or Program folder for a mod.  You must either copy the engine files to the file directory you placed the GOF 2.5 files (not recommended but it works), or launch Maelstrom with a shortcut, where the 'Start In' property of the shortcut is the path to the GOF 2.5 directory (this is the recommended way) that contains the start.ini and Program/RESOURCES folders.
