DUMMY.BIN in God of War

Well, I was bored and started looking in some PSP games with UMDGEN and I noticed God of War: Chains of Olympus has a nice big BIN file called DUMMY. Now, with something this obvious, this must be dealt with. Optimizing didn't even touch it though. I'm pretty dumb with UMDGEN, so how do I get rid of it? Do I dummy the...DUMMY? LMK, I could save a nice chunk of space with this.

I read somewhere that its a second set of the end credits (devs forgot to take it out i guess) and there are also 3 movies that arent even used that you can dummy i guess (maybe even just delete them if theyre not being used)

But yeah you should be able to just delete the dummy.bin file. The person who ripped that stuff ended up with a 941mb CSO file.

Do you know which 3 movies those are? Also, are there any freeware .pmf players? Got some from Bleach. And what's .AT3? 941 MB ain't that bad.

.AT3 is an atrac audio file.
