I just bought a Sega Nomad, and it has a battery pack hooked to the back. I was wondering how to remove this battery pack. It looks like I should just push it up in relation to the system and then just pull it out, but I am unable to push it up (I dont want to force it). Either it is just really hard to push up, or somebody did something really stupid and glued it in place or something (although I see no trace of glue). Any suggestions?
