From the article:

There's a new ability in the Evercade version of Banjo-Kazooie. When you collect all Jiggies and Music Notes you unlock the ability 'Breegull Boost' which lets BK fly anywhere.

Might be a reference to the prototype that originally allowed BK to do that without pads.

These things are tragically under-advertized, and tend to be a pretty solid deal just for the built in games (for fans of that publisher, of course).

In my opinion, they don't emphasize enough that this thing also plays the entire Evercade line of cartridges, too.

Everybody please go buy these, so that my local game shops might start stocking Evercade carts for easier impulse buys. Okay? Thanks.
