DiiLC is a simple application to download and insert the DLC (downloadable content) or HDLC (hacked downloadable content) into Animal Crossing City Folk savegame file (use Waninkoko’s savegame extractor for extracting savegame file). This application searches the DLC and HDLC files from the distributing servers. It could download and insert four DLCs (for US, EU, JP, and KR regions) and one HDLC that are available at the time when the application is running.

Changes:

Fix a bug for non built-in item trigger
Allow non-Nintendo sender name in DLC letter
