Thank you for trying to help! A few things for the future:
We already get all of the serial code and nintendo zone events as they are made available. We do not need direct contributions or codes for any of them. If you want the files as they come out, you can subscribe to SciresM's Mystery Gift Bot, or get it from the Github Gallery.
Next, if you happen to be at a location (PC Japan, PC Popup Korea, Worlds, Regionals, etc) where they have a local wireless event, then we prefer NTR dumps. These dumps do require CFW, but are thankfully very easy to do.
If you are not able to do an NTR dump, then a WC exported from PKHex is a last resort option.
