Thanks, I had the same feeling that it will not be worth it, also I found this at Nintendo site:
Other...Why don't games from another country work with my system? Can you modify them?
Products made by Nintendo for use in other countries are not designed for use in the U.S. for a variety of reasons, including:
Different electrical standards in different countries
Different TV broadcast standards (i.e. PAL, NTSC, SECAM...)
Different languages (This is a significant issue for operational instructions, precautions, and warnings)
Different government regulations (i.e. warranty, safety, electrical, etc.)
Different marketing requirements (i.e. game ratings, packaging, advertising, etc.)
Because of the many differences, the products are made specifically for each country or region, and there is no way to ensure compatibility. Games and systems purchased for use in other countries will often not function properly in the U.S. or with made-for-U.S. products, or will be difficult to use because of language issues (manuals, warnings, screen text, etc.).
