This demo of Rockman DASH was given only to members of the Capcom Friendly Club.
It contains a beta (early development) version preview of the game that has a number differences from the finished product.

An interesting, though obviously very temporary title screen.

The first thing you're likely to notice is Megaman's head. His hair is a lot lighter and styled differently. His face doesn't look quite right yet either.

It doesn't take long to realize that Megaman seems a bit smaller than usual. Just look at him compared to the Zakobon...

...and next to the sign. Seeing as this is early in development, it makes sense. The creators initially envisioned the main characters to be around age 10-11 rather than 14, so naturally Megaman would be shorter. The upside (which may just be the early game engine at work) is that Megaman seems to move faster. His running and turning both appear to have added speed and smoothness. The downside is that his little legs make it so that he can barely jump at all.
