I believe many friends who were born in the late 70s and 80s are very familiar with Nintendo's "Red and White Machine." This game console accompanied many friends through their childhood. Nowadays, computers, PSPs, Wiis, and other electronic gaming products have replaced the "Red and White Machine," but those classic games like Super Mario and Contra on the Nintendo Red and White Machine have been deeply imprinted in the hearts of many. Now, Apple's first smartphone product, the iPhone, has garnered much attention, and news about its jailbreaking keeps emerging. However, today I am not here to bring you updates on unlocking the iPhone, but rather to show you how the NES emulator allows you to play Nintendo games on your iPhone.
