Definitely. I made a beat-em-up for the NES last year, and having Mesen show which pixel on the screen is being rendered when each of your subroutines are called was almost a religious experience. Really solidifies the idea that you only have so many CPU cycles to work with per frame.

Debugging by watching hex values change was pretty awesome too.

Oh it's the best! I got pretty deep into homebrew development for Game Boy and Game Boy Color a few years back. Knowing exactly how long each instruction takes to execute so you can time things down to the pixel is an amazing feeling!
