well.. if it is a handheld, then u outta get yourself the a/c adapter and a battery pack. lastes up to 8 hours. i should know i got afew. how much they are is a different story tho. of course the battery pack nees recharge after a whuile. so just use a the a/c plug and u wont have to worry about batteries dying out. of course unless ur electricity dies out. not cool. i feel the same way do. no batt. for gba so i can play yugioh eds.
sory this was so long.
