Capcom released a port of "Mega Man X" onto FOMA and i-mode compatible mobile phones in Japan in 2007. "Mega Man X" has also been made available for purchase on the Virtual Console service in Japan and North America in 2011 for the Wii, and later in Europe in 2012, as well as for the Wii U in 2013 and the New Nintendo 3DS in 2016. The game was ported to the Android operating system in Japan as a free download on November 18, 2011. Another remake of "Mega Man X" was released on the Apple iOS (iPhone and iPod Touch) on December 21, 2011. This version is based on the mobile phone version of the game and features touch controls, Game Center support, and a challenge mode with 80 levels. However, this version removed extra life power-ups, and separated the levels into chunks by black screen transitions, as opposed to the continuous scrolling of the original. Weapon and armor upgrades could also be purchased with actual money to ease the game's difficulty.
