The games are nearly identical to the originals, including the lower GBA resolution, but now the bottom screen displays character wallpapers, which change depending on the action of the top screen. Once seen, these wallpapers can be viewed from the main menu.
The DS has two extra face buttons compared to the GBA. The default button mapping has been cleverly designed so that you can use any preferred two-button layout simply by choosing one of the sides of the four-button diamond. Players can also change the assignments from the menu using the touch screen (for instance, if you wanted to swap in the shoulder buttons).
The collection even includes digital versions of the Japan-only e-Reader cards for Mega Man Zero 3. Once activated, these mod cards actually change elements of the game, and their inclusion really makes the collection complete.
The Zero Collection has been designed for Mega Man fans new and old, and is a nice packaging of the four solid Zero-saga games. Check out video of the compilations's menus and gameplay below.
