GiriGiri, developed by Shinya "MegaDeath" Miyamoto, was actually the emulator that Sega bought and, eventually, became the "Cyber Disc Service".You guys got mentioned on Digital Foundry..
SSF already emulated games before the supposed first release of GiriGiri, that never came out for obvious reasons. After that, GiriGiri was leaked and hacked under various names, being the infamous Cassini-gav (or just Cassini) the most famous hack. It was pretty popular back in the day because it had WAAAAAAAAAY lower requirements than SSF. It took quite a while to have a machine powerful enough to run SSF at decent speeds, 20 years ago.
SSF ran the first commercial games around August 2000.
