The page does say it, though it might be easy to overlook if you don't understand the significance of the statements:

> Zero setup

> Direct to gameplay

> Distraction-free gaming

> Use SD cards or other external media as carts

The 90s gaming console experience was:

1. Grab your game cartridge.

2. Insert cartridge into console.

3. Turn on console.

4. Play the game.

There are no steps between 3 and 4. The console booted directly into the game. It was fast and there was no messing with multimedia experience stuff (like Xbox or PS later introduced).

I have no experience with Kazeta but this is what I would expect from its homepage.
