Summary	01038: desyncing gfx
Description	In some game, some but not all gfx (usually on the ground) seem to desync/shake up and down during gameplay.For example the first two enemy sprites on the ground in xevious. The right one shakes, the left one is in sync with the background. When you shoot both, the "crater" on the right is in sync with the background and the "crater" on the left side shakes. Kinda wierd. Update: In gunfront, background & sprites are not synched. It's noticeable in the desert with all the tanks on the sand. (For all these games) the sprites probably need to be buffered by one frame. Update: The sprites on nemesis seems to lag slightly behind the background graphics..... This can be seen evident on the vertically scrolling levels..... Eg the guns seems to wobble when scrolling up and down..... they don't quite stick to the ground.
