Anybody find any cheats or memory hacks, trainers etc...?

Look under GamecopyWorld ther is a Trainer for version 1.02 and 1.05

The easiest way to cheat is to play the missions in the Original War Editor(You can then for example spawn any vehicle/etc you want). To do so you would need to create a new mod using the editor and extract <Original War>\Disk2\am01.OWP to your mods directory (They are under <Original War>\mods\ ) using PakView (Its located in the Original War directory, i don't know if GOG's installer creates the shortcuts in the start menu).

P.S <Original War> represents your original war directory in the above text.
