Hi guys. I havne't been able to get a good answer about htis, so I hpe it's ok if I post it here. I was reading through the DS instruction booklet on my new DS Lite, and it mentioned unplugging the AC adapter from the wall when it's done charging. This may be a dumb quesiton, but is it bad to play a game when it's plugged in to to wall? Is it pointless because it'll still used the battery power or does it just use the wall power when it's plugged in? Also, is there any negative effect to leaving the DS Lite plugged in when not in use? Thank in advance. Sorry to bother with what's probably a dumb question, but that instruction about taking out the AC adapter made me think.
