Is this normal?

[per]

I recently did the LCD mod on a Lynx II, and there is this one artifact in STUN Runner I just noticed. I can't remember if it used to be like this before, or if the slower original screen did a better job at hiding it.

 

Some frames, the background of the first lines of the score panel will be green. How much is green seems to depend on factors like how many sound effects are being played or how much goes on at the time.

 

More or less all reference footage I can find of this game is from emulators, so it gives me no certainty if it's supposed to be like this or not. It seems to be something like it in the clips, but the effect starts at the beginning of the first line and very rarely extends into the area with much exposed background. On my unit it seems to start in the middle of the first line and not at the start of it.

 

So, is this normal? Is it due to low battery? Is it due to differences in the Lynx I and II chipset? Or can it be something else?

Are nobody able to test this? I thought S.T.U.N. Runner was one of the more common games for the system...

Just tested my copy of S.T.U.N. Runner with my McWill-modded Lynx II. At first, I noticed that the horizontal row of pixels directly in line with the crossbar of the T in the word "TIME," as well as the horizontal row of pixels beginning above "MPH" at the center and extending alway the way to the right, all tended to pulse, depending on what else was going on graphics-wise. As I get further into the game, I'm starting to see the green lines pulsing exactly where you see them on yours. My guess is that these pulsing rows are a normal part of the game code, but unnoticeable on an un-modded Lynx. I hope that info helps you somehow.

I can confirm what you are seeing on Stun Runner. I just recently installed the LCD mod on my Lynx 2 and I see the exact same thing.

Thanks for confirming!

 

Wonder if there is a difference with the Lynx I. I do believe the two to have slightly different timing. Comparing with the emulator, there the "pulsing" row exactly lines up with the upper line on the stage overview screen, and never extends into the next row at all.
