No.00294 RansAckeR Tester Mar 20, 2008, 22:35	reproduces in 0.123u6 regression is 0.114u1 my guess: Substantially changed the TMS340x0 interfaces to allow the CPU emulator to directly manage the video screen. Glitches in several games are now fixed as a result (for example the flashing screens in NBA Jam are now gone at last). [Aaron Giles] converting VIDEO_UPDATE( xtheball ) to xtheball_scanline_update(...) went wrong?

No.00298 RansAckeR Tester Mar 21, 2008, 08:01	What I also noticed is that before the regression it did not work entirely correct. If the ball was more or less on the same Y-position on screen as a markpoint it was only drawn half, like after the regression. Perhaps that could be a hint.
