You can add your own heroes/heroines, you know. Go to the Hero tab in the database to set one's base stats and such (you can edit the ones there, delete them and use the space for a new one, or simply increase the Array Size so you have some blank space.)

After that, you can import a battle charset / charset (walking around) / faceset to complete the character. (Don't forget that you'll need to set up the battle animation on the Animation 2 tab in the database. Same as with the Hero tab, edit/delete/increase array to make your own)

Download those two ghost animations (From FF6) and import them using the Resource Manager located in the Tools menu. Click on BattleCharSet on the left frame and Import the ghost images. Then, go to Animations 2 to play around with building a battle animation set that works. I guess that a summon doesn't need a faceset or charset..

As to "password" functions - that tutorial's probably from RPG Maker 2000. In RPG Maker 2003 (at least RPG Advocate's version) it's called "Key Input Processing". Same thing, different name.
