Exactly what it says, alternate SND files for Kamek's Reiko.  When you want to hear someone other than Flonne and Etna, just use one of the other four voices.  Note that two of them are specifically for Dark Reiko (having a limited vocabulary similar to Etna).

Also included as a bonus: A Wizardheimer SND file for Kamek's Kamek.  Tired of "hocus pocus"?  Now you can listen to "I'm an evil koopa wizard!" until you're sick of that too

Have fun.  Feel free to call her Not Reiko or Fake Reiko or Clone Reiko or whatever else you can come up with.....
