RockNES is a proprietary Famicom (NES) and Famicom Disk System (FDS) emulator.
This is arguably one of the oldest, if not the oldest mature Famicom/NES emulators in existence. Its public formation started in Version 0.51 on June 29, 1998. According to the oldnews.txt document found inside the official website, it was originally called "xNES", but was renamed to the current RockNES title on August 22, 1998, to avoid confusion that lead some people to believe that it was for Unix. The title was first seen in version 0.53 Release 3 (On August 23, 1998) the day after release of xNES 0.53 Release 2.
DarcNES was another multi-system emulator for multiple platforms made in 1998-2001 by Alastair Bridgewater (a.k.a. Nyef), that mainly focused on NES emulation. Unlike RockNES here, it was abandoned few years after its creation.
