Christ added two more maps to his AMAP4DS v3.1, the homebrew app for people with no sense of direction.

If you're new to AMAP4DS (a map for DS), it's a simple and easy-to-use map viewer originally designed for metro and bus maps. If you're constantly getting lost in Belgium, you can now download the Brussels metro, tram, and bus map. If you're in Portugal, the Lisboa metro-bus map ought to help get your bearings back.

• Included maps. It features quality maps including Argentina, Australia, Austria, Brazil, Canada, China, and France.
• Add more maps. If you happen to be in an area not yet covered by AMAP4DS and you want to add your map, you can download the AMAP4DS-Open-Source package here. It includes a tutorial on how to do it.
