So I revisited Spore Hero Arena recently, and decided to give myself a second chance ripping from the game after 2 years.
The game uses .nitro_archive files for literally everything. Seeing that there luckily was a post on a thread here about these same kinds of files, I tried the bms script that was made to handle these files, but it didn't work with the files from Hero Arena, and I can see why. I opened a few of the files from both Hero Arena and the Sims game in a hex editor, and the hex data in Hero Arena's are a MESS compared to The Sims files in that one thread. The biggest problem would have to be the fact that the filenames are in each individual NTRO file and are most of the time overlapped by other data, not even showing the full file path most of the time (probably because compression?). After a bit of failed tinkering with the bms script to try to get this to work (which I'm pretty new at), posting here was my last resort. If anyone can help me out with this, it would be greatly appreciated.

The files from the game

Sorry for being gone almost a week. Anyway Thanks aluigi! The script didn't quite exactly do what I expected, but it will do, and at least I got files out. I'll leave figuring out which files are which to me, as luckilly theres still path data inside them.
