Iso + Mp3's w/out cue: Easiest thing ever. If you have and know how to use nero, just make a mixed mode cd with the iso files already extracted. if not... Get Nero (I'm using 6.xx). Get WinRAR (Or any other Iso-extracting program) Extract all the files from the Track01.iso to your project folder (e.g. Metal Slug) Put All Mp3's in same folder (really doesn't matter where they are, just to lessen confusion) Run Nero, set up a "new compilation" which will be "Mixed Mode CD" --Default settings should be fine, but if you've changed them: --Iso Level 1 (Level 2 is probably fine) --Mode 1 --ISO9660 --"Joliet" checked on --"Allow path depth of more than 8 directories" checked on --"Allow more than 255 characters in path" Drag the contents from the iso (not the mp3's) into the "New" icon Drag the mp3's into the window underneath (it'll say TRACK, TITLE, DURATION..) "Burn Compilation" which is under "Recorder" OR just hit the icon with the match under a cd Done. it's worked with 10 games so far. and to be honest, i wrote this up reeeeally quicky, so i might have screwed something up. hope not, but i'm not checking. someone can find it if it's a mistake. I almost forgot. of course your xbox needs to be able to read the kind of disc you're going to use. it's good to be a samsung owner. Almost forgot this too. if you can make your mp3's louder before making your disc, i suggest you look into this. i had to make mine about 5x louder before i was content (i was happy at 8x, but that was me)
