PKHeX plugin to import and export generation 3 event files. This includes the following:
Mystery Gifts (WC3) for FireRed, LeafGreen and Emerald
Mystery Events (ME3) for Ruby, Sapphire and Emerald
e-Card Trainers (ECT) for all generation 3 games
e-Card Berries (ECB) for Ruby, Sapphire and Emerald
Wonder News (WN3) for FireRed, LeafGreen and Emerald
All checksums are fixed on import.
If you want to edit any of the files you need to use suloku's Gen 3 Mystery Gift Tool.
How to use
Put the plugin into the plugins folder in your PKHeX directory, then access it from the Tools menu.
Note: Win 10 might block DLL files downloaded from the internet. In that case right click the plugin file, go to properties and check "unblock" (as seen here).
Example of how to unblock:
Kaphotics for PKHeX.
suloku for his Gen 3 Mystery Gift Tool.
