Altirra 1.8 Color Adjust Settings

Recommended Posts

I Really Like This Emulator. it's been a great tool for testing and Doesn't do a Bad job playing games either.

 

I of course will always be partial to the Real Hardware. =)

 

 

After playing with the Color Adjust settings for quite a while I Think I have come up with some settings that are really close to a Real NTSC Machine (I'm not Sure about PAL because I've never owned a PAL Machine).

 

 

I'm Very Picky about my color settings so I spent the time and thought everyone else would benefit from knowing what I came up with. =)

 

Here are my settings for the "Adjust Colors" selection under the "System > Video" pull down menu.

 

 

 

Hue Start: -50

 

Hue Step: 27.5

 

Brightness: -4%

 

Contrast: 100%

 

Saturation: 30%

 

Artifacting Phase: 189

 

Artifacting Saturation: 200%

 

Artifacting Brightness: +10%

 

 

 

Hope this helps. =)

Yeah, like that..Nice one...

 

Thanks. I use 4 Different Games To Set the Colors By. I use these when I'm Retrofitting an XL with the S-Video Kit that I sell. Since I include new Power supplies with all the systems I always have to re-adjust Hue Step Pot in the XL. So I decided to use the same 4 games to adjust Altirra.

 

1 - John Harris version of Frogger (Look at the Very Top Logs. they should be Dark Brown With a Very Slight Green Tint on Them and the Time Line At the Bottom should be Red.)

 

2 - Pole Position (Look At the Sky It should be an almost Periwinkle Blue. a little Darker and toward the green side from sky blue.)

 

3 - Pac-Man (On The Menu, The "Press Select for 2 player game" and Etc should be a good solid Light Green and the word "Select" A Solid "Pac-Man" Yellow)

 

4 - DropZone (The Ground Should be a Good Solid Brown just before the point of Turning Red)

As said before, thanks for the sharing, its nice to see a formula to the colours as opposed to my hit and miss approach :)

Seen and adjusted, only one thought, you are using an NTSC machine, I wonder if someone would do the same with a PAL machine using the same sort of test guidelines, just for the sake of choice.

 

Either way i still like the look of yours.

Cheers Sal, changes entered.

 

A PAL set would be nice but as and when or indeed if it can be done.
