Big Endian is already supported by my script, and your sample works - no work needed :D Oh man, I now see I was not using the latest version of your plugin, I downloaded the one from this thread but there are 2 more versions linked below it (in other topics) :D My apologies and thanks for your awes...

Hi, I was looking at the game Carnivores Dinosaur Hunter Reborn, and it uses GR2 files as well, though they are the Big Endian kind. Are you interested in adding support for that, or accepting patches for those?
I've attached a sample in case you are interested.
