37. When she brings home a cat, you lock it in a box with a radioactive substance and a Geiger counter.

In DBZ, though, when two individuals are about to fight they stare at each others bragging about their power (until Goku gets OVER 9000!!!!!!!!!) for about three episodes until the fight finally begins and the second hit comes several minutes after the first punch.

I'm of the opinion that resetting the group port is not necessary. Axe's direct key input routine has never done so, and if it didn't work, I'm sure we'd have heard about it from any one of its hundreds of users by now. (I did actually hear about problems a few times, but simply upping the delay seemed to fix any issues)

For reference, the current version of the direct key input routine explicitly waits for a fairly generous 40 cycles, or if you want to count the cycles of delay in the out/in instructions themselves, 51 cycles.
