I think way earlier in this thread someone mentioned that he actually phoned LucasArts and was told you can't play as Boba. And the only extra codes I know of are the cheats I mentioned a couple of posts above this (jetpack, health, etc) but you have to buy the appropriate cheats system to use them. I haven't really stopped playing this. I finished the main game and started a second using the unlimited jetpack & health options. That is lots of fun. And on the weekend I played through the 'Longo Two-Guns' level with unlimited health and ammo. Now that's a good stressbuster!
