I am become death, the destroyer of worlds
I made a post earlier about scanlines showing in high contrast areas of the screen but ONLY when you move your unit:
Apparently, this isn't the whole story though. Interlace graphics also seem to appear on objects moving at high speed. The DrMDx menu and the game Rockdodger are good examples of how this looks. The images to the right show the original screens and to left how they are distorted on the GP2X's LCD:
On the DrMDx menu the "X"'s that are moving across the screen have scanlines. In Rockdodger the rock sprites are also clearly "interlaced" when they move across the screen.
The important question is why. I can think of several answers:
1. It's a normal limitation of the hardware. No fix is possible.
If this is the case I wonder if the GP32 has the same limitation? If not, why put inferior hardware on its successor? Wouldn't make much sense.
2. It's a hardware fault. Non fixable through software
If this is the case then does it affect all units or only a few? Can the affected units be fixed in hardware somehow?
3. It's a software error. Fixable
If this is the answer then there's no real problem. The question is only what the error is, how to fix it and when it will be done.
(Note: On my unit the LCD tweaker doesn't appear to help at all with this problem).
I'm sorry if this issue has been covered already but I couldn't find any concrete information. Some people say they have the problem, some say they don't. Some say it's been fixed in the latest firmware. Some say it was fixed but is now back in the latest firmware. Others say they've never had it at all. Very confusing, to say the least and I'm surprised it isn't doesn't raise more comment.
Edit: I'm also wondering whether both issues (interlace when moving the screen and interlace on sprites moving at high speed) are in fact the same problem. From the viewer's standpoint, moving the screen itself and moving objects on the screen is the same thing.
