Quoted from kguenther6:
This was not intended to stop slide saves. Per IPDB.org:
Slam Tilt —
Tilting the game so violently that it immediately stops all games in progress and reboots (EMs only go into game-over mode).
Easily achieved by kicking the coin box or lifting the machine past horizontal. This type of behavior will also get you thrown out of an arcade and is considered very bad manners.
This is not the same as a slide save.
Yes, only the EM's and a few SS would be game over. The others would tilt.
There were three types of slam tilts.
1: slam tilt on coin door. "Easily achieved by kicking the coin box "
2: ball roll slam tilt on front side of cab. "lifting the machine past horizontal"
3: lateral slam tilt on the bottom side of playfield. Was activated by shoving the game one side or the other. Same as a slide save that moves the game more then an inch or two.
The IPDB only references to two of the three.
"Tilting the game so violently that it immediately stops all games in progress and reboots "
And how do you tilt? By moving a game. And how do you do a slide save? By shoving the game to one side or the other or sometimes side to side.
"This type of behavior will also get you thrown out of an arcade and is considered very bad manners."
Correct. Any of the arcades I played at would have kicked you out for moving a game like in that Congo video no matter how much you tried to claim it was a slide save.
