I downloaded an iso of ninja gaiden (and before you call me a thief, yes I own it; but I've been too busy to learn how to make my own backup right now and I wanted to test out how running a game off my hdd works). The problem is that after I extracted it I noticed that it has more than just a default.xbe. It also has a dashupdate.xbe that's about 50MB as well as a downloader.xbe, ninjatomoe.xbe, ninjatrilogy.xbe, and an update.xbe. Can anyone tell me why these are here and if I need them? I'm not really interested in a 50MB dash update so some insight into this would be appreciated. Thanks. Gulliver
