What about arcade (forget NeoGeo) ? Looks like those rules fail as we can't set a generic viewport : Mame handles the real resolution of games, and nothing is stretched to 4:3 unless forced or native ? That would mean a per game viewport 720p: top/bottom : 0px, left/right : 160pxħ20p just has 160px left on left as well as on right => we can't let retroarch shrink a 1080p overlayġ280x1024 as 32px left on top as well as on bottom => worthless.If so, here are the margins left for each mode : The integer scale resolution is the same for any console, but must be calculated according to the screen resolution :.we need to keep the 4:3 ratio for consoles.This post is for Overlays but for perfect overlays, a screen ratio must be all of your posts give such a headache lol But at least we move forward On hi resolution, 1280x1024 or 1920x1080, we can use non-integer scale, 99% of people never seen the non-integer pixels.Īll these "equations" gives a headache ? Sure. This is (for me) the "perfect way" to display a NeoGeo (or other 4/3) game on a 5/4 LCD monitor.įor those who say, the honrizontal scale is not an integer scale, i answer : On a fullHD (with Perfect Pixels) the screen with Integer Scal must be : The real aspect ratio of a game is 4/3 in fullscreen. Resolution is 240 (vertical) but only 224 pixels are displayed. (LCD pixels aren't exactly square, lets forget that). (PP or Pixel Pefect can be used only with square pixel). There is a lot resolution and lot of game console, so we must only try to respect 4/3 format on your monitor.įor best image quality, we must use Integer Scale. SMS use only 256x192 but the resolution is 256x240. On your link, you can see all consoles use 240 pixels (vertical) but not all viewport is used. In other words, any console meant to be played would have the same fullscreen viewport ?īut is you activate Integer Scale, the size would be : 1280x960 The core scales the game to 1440x1080 on a 1080p screen. 4/3 = 1.33 !!Ī game is done to be seen on a 4/3 screen in full screen ? So is aspect ratio is 4/3 but not X pixels/Y pixels.ĬPS1 games have 384x224 resolution. Pixels are not square on TV, NES and others plateformes.ĭouble Dragon is made to be seen on a arcade monitor, a 4/3 screen in fulsscreen. This is a 4x5 screen (1280x960) but the result is 4/3 screen. It is pixel perfect (or integer scale on) so the scanline is perfect. This is a true 4/3 aspect ratio of a NES screen. The aspect ratio of an image describes the proportional relationship between its width and its heightĢ56/240 (or 16/15 ) is not the Aspect Ratio. NES screen is done to be seen on a 4/3 CRT in full screen, so NES is 4/3 Aspect Ratio.
