Awesome games you have found out about through emulation

The biggest ones for me would be Super Mario RPG and the Super robot wars series.

The fan translated Tales of Phantasia on SNES was also my first ever experience with fan works.

For me it was the whole sega lineup... Growing up as a Nintendo nerd and a later sony one. Finding old dos Kfusion was rather magical( I can safely affirm to be a believer in that Blast processing sect ).
My experiences with sega prior to the "Internet age" was quite limited( apart from enjoying a lot of their arcade lineup ) and seeing some of the megadrive, Dreamcast classics via shop kiosks.
