How to turn created player into real player?

I know that I should change ISCREATED to False and few others, but still, when I try to play with him, it crashes. So which are all things I must do

Basically, that's all you need to do. To make sure he's using a custom face you'll need to change his FACEID in appearance.dbf to -1. It shouldn't crash though; that's usually a sign there's an invalid value somewhere or depending on how you edited the database, perhaps a corruption in the file.

Thanks I forgot to put FACEID to -1, now it doesn´t crash

You're welcome, glad to hear you've got it fixed up.
