So this game is programmed for PAL Atari's?

My understanding is that it works on both NTSC and PAL, but it uses overscan which is clipped on NTSC screens. So it's playable on NTSC but the stats at top and bottom can't be seen.

I would clarify that to say it depends on the monitor used on your NTSC Atari. I use an LCD TV for my XEGS (which I realize is a heresy for some of you) and I can see the stats on the top and bottom of the screen. On the high score screen, the bottom is slightly cut off but the high score is still viewable.

I am very happy that the developers spent the time to make sure Time Pilot would run correctly on an NTSC Atari. Someday, maybe I will have the space and correct monitor to make a PAL Atari work correctly in the US. In the meantime, I am grateful that European developers have not ignored us.

Does the PAL version depend less on overscan than the NTSC version does? I mean it is not given that PAL TV's are more generous in the displayed area, in particular not older sets connected through RF, if anyone still uses it.

 

For example Delta on the C64 uses a lot of border sprites, which are barely visible on many TV's and monitors that don't let you adjust screen height, so it is not the first time in computer games history that part of the screen may fall outside of the comfortably displayable area.

On both systems it's a safe bet that on a CRT you'll lose about 80 scanlines - so we say 40 for a Progressive display.

That equates to showing 223 on NTSC which is 17 less than the Atari's 240, so losing the top and bottom row of text in a 30 row display.

On PAL it equates to showing 272 which is still 32 more than Atari generates, so providing the black border which is about 2 characters height on top/bottom.

 

I have seen TVs that truncate a PAL display but generally it's a rarity and usually means it's badly adjusted and the aspect ratio of normal TV will be too tall and skinny.

 

Looking at the DList in the game, it starts right at the top of the possible display area but only uses 226 scanlines so the likelihood is that more overscan would be lost at the top (score) than the bottom (stats).

 

The problem with Atari is that you can't easily provide an offset adjustment - for the Display List it's trivial to just put blank lines to shift the display downward but that means the PM graphics would be shown in the wrong relative position.  Fairly major programming changes would be needed to allow shifting them as well.

Still not clear if this game is PAL or NTSC?

 

Sounds seem too fast in NTSC, however.
