Thankfully no Turbobs sacrificed, but the Dreamcast is apparently surprisingly resilient.
While playing MvC2 for hundreds of hours with dudes, many Dreamcasts died in my presence. There was a problem that would cause the 4 controller ports to just stop recognizing controllers. Over time the broken DCs started adding up so at one point right after Sega had pulled the plug on my beloved Dreamcast a guy I know bought 4 for $50 each and we were determined to figure out if there was something we were doing that was ruining the things.
Through trial and error, we finally found out what was causing all of our Dreamcasts to end up with dead controller inputs. If an Agetech "green goblin" joystick was plugged into controller port 2, and while the DC was on you then plugged a MAS stick with MAS's default DC plug and a 360 optical stick it would break a DC. You'd think that the knowledge of this would stop us from doing precisely that but it never did.
The fix somebody posted online was to put in a resistor with more ohms than the default one on the control ports.
