I recently tried to use these codes:
and found out that these require a US/NTSC Megaman Battle Network 4 Red Sun game.
However I only have a Pal (Europe) one and the saves aren't compatible between the two games.
I heard it is possible to convert codes between regions using the Delta Maker Application, however I have no Idea on how to whatsoever.
I would be really grateful if anyonoen could teach me how to convert thes (admittedly old codes).
Thanks in advance:
