Game Listing


The game listing is not known fully yet, but we have seen a screenshot of the first part of the menu. This is what it has:

SUPER MARIO - Most likely the very first Super Mario Bros. game

SUPER MARIO 2 JP - This is the Japanese "lost levels" game, presumably.

SUPER MARIO 3 - Most likely Super Mario Bros 3. What region it is is unknown, but it's probably the Japanese version.

DR MARIO - Most likely Dr. Mario, the puzzle game.

MARIO ADVENTURE (With a "NEW" Symbol) - It could be the infamous "Mario Adventure" ROM hack of Super Mario Bros. 3.

Nintendo's Response

Nintendo of America posted on Twitter that Mario classics are available on the virtual console and there were great new Mario titles on the Wii U, citing that there was no need to ship a cartridge all the way from China.

"You can always download great classic Mario titles from the Wii U and 3DS eShop, and there's always great 2D Mario titles such as New Super Mario Bros. U to check out on the Wii U and 3DS consoles, with no need to ship a cartridge all the way from China!"

Nevertheless, fans are excited to see a new multicart from Coolboy announced officially, instead of being released without notice.
