Steps To Reproduce
Additional Information	While I can't precisely identify for certain which version this regressed - I can say that it happened between 0.105 (correct) and 0.106 (incorrect). Checking sources for anything video related regarding st0016 driver shows that 0.105u5 as the offending update. 0.155 changed driver st0016.c to simple_st0016.c

No.03440 Kale Developer Dec 30, 2008, 23:11	Chars are simply flipped on the y-axis but with correct x/y position.
No.03443 Tafoid Administrator Dec 30, 2008, 23:46	Made corrections to the summary per Kale.
No.03445 robiza Developer Dec 31, 2008, 12:58	probably wrong: flipx=st0016_spriteram[i+3]&0x80; flipy=st0016_spriteram[i+3]&0x40;
No.03446 Haze Senior Tester Dec 31, 2008, 14:04	it's seta hardware which has lots of levels of indirection in the sprite rendering and such. IIRC it was broken in order to fix something else. Chances are those flags are right, but there is another flag to tell it to use the flip from the parent object and ignore the individual tile attributes...
