If you played Megaman 3 on FCEUltrax or Mednafenx you'll notice a little flickering line above shadowman portrit. I cant remeber if this glitch was in the actual game I haven't played it in years so I dont remeber.
I tried to test it tonite but I keep getting the damn gray screen of death.

So I posted the problem on the Mednafen boards and the administrator responded by saying it happens on real a NES hardware.
I'm pretty sure he's mistaken(or I have a bad memory

) anyway I tried the game on Rocknes and a few other EMUs and the line was gone.
"wooptie-doo a line glitch get over it...blahblah.
I can live with it but I'll feel better knowing what he said is 100% accurate
So if someone with a working copy and NES would be kind enough to check this out I would appreciate it.
