Pokemon Red, Blue, Green, and Yellow have been downloaded 1.5 million times on the Nintendo 3DS eShop.

Nintendo made the announcement at the company’s fiscal year presentation. Nintendo president Tatsumi Kimishima noted that while the figure reflects worldwide sales, North American fans contributed over half of the downloads.

“More than half of these downloads came from the American market,” Kimishima stated. “Since the start of the calendar year, Pokemon has been the subject of much attention in America, and sales are showing a favorable trend.”

The Game Boy titles released on the 3DS Virtual Console on February 27th, 20 years after their original release. Only three of the four titles were released on the eShop: Red, Blue, and Yellow. A New Nintendo 3DS bundle was released on the same day as the games, and included codes for Red and Blue, as well as two Pokemon-themed cover plates.

Just two months after launch, the titles have found major success. Nintendo stated that they have already hit the top-ranked downloadable title chart for its 2015-2016 fiscal year, which ended on March 31st. All four titles took the fourth place slot in the top five most downloaded games chart, preceded by DLC for Mario Kart 8 and Super Smash Bros.

This year marks the 20th anniversary for the Pokemon series. To celebrate, Nintendo will be distributing mythical Pokemon all year long. Two new entries to the series, Pokemon Sun and Moon, will release this winter.
