Summary 08680: All sets in slapshot.cpp: Some graphics are vertically offset when Dip Switch is set to DISPLAY REVERSE. (possible) graphics are rotated and not flipped
Description Some of the graphics are offset vertically if you set the machine to flip its display. View the images attached and look at the basic text elements or the "BBB" graphics in the opwolf3 sets, or things like "Insert Coin" and "Push Start" in the slapshot sets. The slim black bar at the top of the screen hides some of the graphics when you're in the ice rink when the display is still set just to normal too (top of 3rd image in the left column for slapshot).
Steps To Reproduce 1. run any of the affected games.
2. take some screenshots and remember where you took them.
3. now F2 to get to service mode and go to the dip switch settings. Flip on Display Reverse and exit the service menu.
4. start the game again and take screenshots in the same places.
5. open the images in an editor and rotate them 180 degrees, then compare to the first set of images you made.
Additional Information The opwolf3 sets display is reversed on the very first run, but if you go to service menu or just reset it corrects itself. Has to be the very first run without a cfg or nvram present though.

EDIT: This should have been obvious to me from the start, shouldn't the display get flipped for all these game like T2 does and not rotated? I changed the title to include that possibility.
