By theSLAYERA modified emulator, that is able to connect a main game to a digital copy of the e-Reader, to send files to the intended main game.
Additionally, if you rather not use the .raws provided, we also have e-reader saves with the Eon Ticket already scanned into the e-reader.
Huge thanks to @javier_himura for mixing the VBA versions to craft this,
and also huge thanks to Team Fail, Hacky, Ajxpk, Gocario, Real.96, Suloku any other involved in Gen 3 Mystery Gift research thread, for the e-reader saves.
