UraTama
The EnTama was released November 23, 2005

These Tamagotchis play a LOT like the Entama You can even use the Enwarehouse program with this one but some of the items will be different.
For the Enwarehouse program, look at my entama page.
The Entama instructions will also work quite well with these. The only difference is the Strange character versions.

It is an honor to present Enwarehouse! This little program is for use with your Entama. Enter your travel code, chose what you want, and it gives you your exit code to enter to the Tamagotchi. You can get anything that e-tamago can give you.  Thank you so much Binary for creating this wonderful program! :0)
