Not by importance. Obviously that would be the Linux kernel, GCC and GNU coreutils, and the Firefox web browser, among some other foundational things (code to run my desktop GUI, for example).
So, I'll say my favorite is PCSX2. Ever since they got rid of the ancient plugin architecture this emulator has been getting sooooooo much better, and it was already great! I would add other top tier emulators like Dolphin, DuckStation, SNES9X, SameBoy, and so on. I just love emulators :)
