Hallo "DosPrompt",
vielen Dank für die Antwort. Hat mir super geholfen. Ich habe MM archive bentutzt und alles paletti! Danke nochmal!
"LizardWarrior":
"You need MM archive or DefKa.
With MMarchive you must open H3sprite.lod which is located in data in
your heroes folder,your def's name must be the same as the one of the
def you want to replace.You will see two papers with a + on them,that's
add button,press it and add your def(s).
With DefKa is a lot easier than MMarchive,just select the creature you want to replace."
