    What is the ratio for an actual SNES screen on TV?

    Thanks to all ppl working on the emulator. It gives me chance to recall my childhood memories. And I like to imitate as close to the actual TV screen as possible. I have been using Snes9x with a screen ratio of 8:7, but then I saw from some pics (e.g. the boxart) that the actual TV screen looks wider. I recently tried an adaption of Snes9x, the XE adaption, and found that I can choose a ratio of x1.125 which gives a similar screen as the boxart pic
    So what is the actual ratio? I can't remember that clearly the screen ratio I have played with years ago

    The internal aspect ratio of the SNES is 8:7. What the console actually outputs is 4:3. What you most likely see on those box shots is analog stretching, which was in itself tied to the analog TV sets of old.

    The "correct" (aka without stretching/distorsion) aspect ratio for SNES games is 8:7. TVs normally stretch it to 4:3, but that distorts the picture (squares became rectangles etc).

    And by the boxart you mean this?:



    Because the boxart's aspect ratio has nothing to do with the actual in-game aspect ratio.

    @Fanatic 64: I can't say for sure, but I suspect the OP was probably referring to the screenshots or pictures of the game on TVs, which are found on some games' boxes.

    The standard AR for TVs back when the SNES was current was 4:3, so devs would've designed their games with that AR in mind.

    I see. Never think that what the actual TV shows is a distorted screen. Now I can well enjoy the emulator with correct ratio of 8:7. Thx!
    To better illustrate my question, I should have posted some pics but the message "Post denied." always appears when I tried to insert an image url

    PAL games were stretched in a similar manner, but most had black bars at the top and bottom, meaning the actual ratio was wider than 4:3. Some games added extra pixels at the top and bottom though to compensate, like Super Mario All Stars.

    How do you run games in 8:7? Only options I seem to get out of bsnes (I use v073) is TV aspect (4:3) or stretch (a horrid looking 16:9). I much rather run in 8:7 for widescreen display.

    You can't. The SNES outputs 4:3, and that is what you should be using.

    I'm using Snes9x and there are two options for aspect ratio i.e. 8:7 and 4:3

    I found that many game designers were actually creating 8:7 screens for SNES games. A good example is A Link to the Past. Link's sprite on the GBA ver is exactly the same as the one on SNES with 8:7 AR. So I will just stick to 8:7 AR for emulation

    You are right. I've changed my mind and now I always stick to 4:3, though sometimes game designers may intend to make graphics in 8:7 (like the case of morph ball for Metroid on SNES). Blargg's NTSC filter seems best for me, and I am also trying the shaders on Snes9x 1.53
