G2Map is a map editor for the Generation 2 Pokemon RPGs, namely Gold, Silver and Crystal, written in C# with .NET 4.5. It is capable of editing maps, events, map properties (ex. tileset, music) and wild Pokemon on maps that support them.

Note that the program is still being worked on, and thus is still missing some features, like support for certain game versions (ex. Italian G/S, other European Crystals), and has some inaccuracies, like a few incorrect palette assignments on maps in Crystal.
