@argus1963 goes to the pokemon centers in japan for us and dumps the event. Long tutorial shortened, in 2 minutes you can do this by taking a CFW 3DS with BootNTR and doing the following:
Load BootNTR with 3.2 or 3.6. Open the game and get to the part of the redemption where it asks you to press A to receive it. Then open the NTR menu and go to process manager. Sift through the list until you find a process named Nijiloc. The process names can be found via the info option. Once that process is identified, choose dump, then 0x80000000 region. Wait (up to 30 seconds). And you are done. Copy the DMP file and send it to us or use the WC Dumper to dump the WCFull file.
Anyone can do this for local wireless and infrared events and I encourage everyone to go out and try it if they are able to attend an in life event. As for online/nintendo zone/serial code events, we have bots that scrape and get this stuff for us.
