What do I do with bin files?

So, I'm trying to get some sprites out of my ISO rom of "Tactics ogre: Let us cling together" for the psp. I found a sprite sheet, but it was for the Snes version version, which lacks several things. I've done some basic ripping, but am still new to this. Anyways, since its an ISO, I decided to mount it on Daemon tools, which I believe works because I got several files from it. Let me know if I should be doing something else here. Anyways, the only images I got (can't recall what they were) were only things like title screens. The majority of the ISO were bin files, and they all appear to contain data, since their names were "DATA.bin." Anyways, I did some research, and I somehow found out that if I made a CUE file, I could use daemon tools to access the BIN files. Well, I made the cue file using notepad (I had to input some text or something) and tried mounting it, but it just stops after I try to mount it, daemon tools jusr stops responding. I'm going to a class for like an hour, so I'll let it try to open it, but I was wondering if anyone knows either:
A) Why daemon tools is doing this?
B) What else can I use to open bin files?
Thanks for any help!
