In December 1993, the Famicom received a similar redesign. It also loads cartridges through a covered slot on the top of the unit and uses non-hardwired controllers. Because HVC-101 used composite video output instead of being RF only like the HVC-001, Nintendo marketed the newer model as the AV Famicom (AV仕様ファミコン, Eibui Shiyō Famikon?). Since the new controllers don't have microphones on them like the second controller on the original console, certain games such as the Disk System version of The Legend of Zelda and Raid on Bungeling Bay will have certain tricks that cannot be replicated when played on an HVC-101 Famicom without a modded controller. However, the HVC-101 Famicom is compatible with most NES controllers due to having the same controller port. Nintendo had also released a 3D graphic capable headset. However, this peripheral was never released outside Japan.[citation needed]
Output:
What month and year did the Famicom receive a redesign?
