MK2 for Super NES
"Frozen thundercould on title intro"

I found this out by total accident today. I'm not sure if this works with any turbo controller or not, but I have a Super Advantage (or whatever the hell the joystick is called) plugged into the second player's controller port and I didn't realize that I had slow-mo turned on. When you turn on the game (and the slow mo is enabled) it goes to the legal info... then the Acclaim screen... and now at the screen where lightning is flashing in the clouds before the MK2 logo comes up, the game will be stuck at the first lightning strike.

Instead of going: "boom... boomboom boom... MK2 LOGO!" it just goes "boom..." and the screen stays stuck at the flickering lightning cloud at the lower left corner of the screen. And it doesn't lock up or anything, it just keeps flickering like it was meant to do it or something.

Just thought this was interesting since I haven't heard it mentioned before.
