Can the Game Boy Advance SP play Game Boy Advance games from other countries?
All of Nintendo’s hand held systems in the Game Boy line and including the Nintendo DS Lite, are capable of playing games from anywhere around the world. There are no regional lockout chips or codes installed on the units which prohibit game play, unlike the Nintendo home console lineup. Game Boy Advance games sold in the USA for example can be played on a Japanese Game boy Advance sp, and will be displayed in english regardless. And all Japanese Game Boy Advance games will appear in Japanese language when played on a North American Game Boy Advance sp.
