No.00258 zsoltvasvari Developer Mar 19, 2008, 13:42	The column sprite (0x26d2) has a position of x=0x10 and y=0x0000 all the while when it's not visible. Then the game starts scrolling it to the left and it's made visible. Adding 32 to the X coordinate of the sprites makes the column scroll in smoothly, but that screws up the left side of the screen. I'd love to see a video of this running on a PCB, just to verify the relative position of the varioud screen elements.

No.00765 Stefan Lindberg Senior Tester Apr 22, 2008, 19:00	Is a video from the PCB still needed?
No.00774 Haze Senior Tester Apr 23, 2008, 15:34	videos never hurt anybody.. btw are the shadow force videos still somewhere? I'd like to look at the raster effects, and check all the object / layer alignment on that too.

No.00822 Stefan Lindberg Senior Tester Apr 26, 2008, 16:15	Now i have done a recording from my P.O.W PCB showing the pillar: http://www.ym2149.com/pow_pcb_recording.zip
No.01636 nicolasa Developer Jul 15, 2008, 09:57	It appears that the game writes the correct value in sprite RAM, but then overwrites it. Could be a vblank timing issue, or we might be missing a "sprite DMA start" command.
