(Feature request) Upscale game while keeping the same ratio

Open Tovarichtch opened this issue 1 year ago • 2 comments

It's currently working only for Sega Race-TV and Primeval Hunt.

Fullscreen is enabled on both my 2K monitor and 1080p TV. KEEP_ASPECT_RATIO is what stops the upscaling from stretching the entire display.

I've noticed that in Primeval Hunt, it breaks the light gun accuracy because black borders are dead zones instead of being empty zones. The idea here is to keep monitor resolution (e.g.: 16:9) while the game display stays to native (e.g.: 4:3).

Primeval hunt has its own way to change the way it displays the screen. Keep aspect ratio only works in SRTV.

A user tried initiad4 and 5 on a 4:3 monitor. Sadly, it's cropped. The idea here would be to keep the same ratio, and add horizontal black bars to fill the void while keeping the same game display ratio.

You should re calibrate the guns, and report back.

ID4 and ID5 are meant to be played at 16:9 res. I am testing a new functionality that stretches. I would like to have it tested in a 4:3 display.

I've tried, but I can't. Test mode shows both screens instead of just one. Default value is still good nonetheless (of course in fullscreen).

Now, with blitting implemented, the games should scale properly, but you have to set the right resolution in the config so the aspect ratio is kept. Example: If your monitor resolution is 1440x1080 (4:3) and the game original resolution is 16:9, you will have to set the width to 1440 and the height to 810 to keep the aspect ratio to 16:9.
