Wario Land 4: a matching US/EU and Japanese GBA decompilation

Wario Land 4 reconstructs source for the US/EU and Japanese GBA releases and builds ROMs from user-supplied originals. The author reports C equivalents for all functions while some assembly sites remain; the build uses agbcc and checks its output against version-specific MD5 hashes.
