Two new CoinOPS setup for correct pixel aspect ratio

Hey Guys,

 

After almost one hour of fighting the emulator, I was able

to get two new setups for some important games that I was missing.

 

I did create (after Hex Editing the XBEs) two new CoinOPS, one

for the size 240x256 (Legendary Wings, Avengers and some others) and

256x256 (Vigilante, Spartan X and few others).

 

Legendary Wings is a important title, and it should be played on a pixel

perfect screen display, no blur, no fancy filtering, no distortions. It worths

it!

 

Here are the sizes and positions for both emulators:

(Only for NO ANTIALIAS and NO FLICKER FILTER usage!)

 

 

- 256x256

 

ScreenUsage_X = 0.801562

ScreenUsage_Y = 1.066667

ScreenPos_X = -0.029687

ScreenPos_Y = 0.100000

 

- 240x256

 

ScreenUsage_X = 1.332813

ScreenUsage_Y = 1.066667

ScreenPos_X = 0.001563

ScreenPos_Y = -0.009375

 

Please note - the 480i/480p modes have 480 pixels on height.

256 * 2 = 512 pixels

512 - 480 = 32 pixels

 

Both sizes do not fit entirely on the screen (on the height) so

I needed to crop 32 pixels out of the screen. It really worths

the price for me, I did left out of the view the top of the games,

where we mostly have only the score information.

 

For those interested on the INI files entirely, drop me a PM.

 

PS. And I will never understand how this emulator works regarding

the screensizes. Doing the correct math, 240 pixels should be

1.333333, value that is 320 divided for 240. However this number

is WRONG when applied to the emulator. It brings distortions and

artifacts! The correct one, on my setup, was achieved by 1.332813.

Strange huh?

 

Another example. On the real world math 256 divided for 320 is

simply 0.8. That's it. But the value of 0.800000 does not work

inside the emulator. The correct value I was able to find was 0.801562.

This is really really hard to get, painful. But anyway, I am glad to be able

to find them and to spread the word to the another PIXEL FANATICS out

there.

 

Cheers guys,

Enjoy Legendary Wings, Avengers, Vigilante and Spartan X with no

devilish blur and cursed screen corruptions!!!

 

Long live to the correct pixel aspect ratio!
