    Interesting, thanks.

    True! There are more roadside objects and usually bigger ones as well as these huge road signs which pass over our head

    But the frame rate seemed similar to me and it's pretty decent given the amount of things that these games handle.

    + OST is amazing
    Well, the soundtrack in the Road Rash games is amazing too but ye, Skitchin went next level with, if I'm not mistaken, a multi-PCM sound driver and some tunes have wonderful PSG leads.

    @Black_Tiger: yup, I did!

    I wonder how the NES would have fared with this game.

    I played the hell out of the Game Gear version of Road Rash. It's hands down the best looking and sounding title of its kind in 8 bits.

    You are right, mate.

    @Peeteris: Dustin's real recordings are always welcome! His channel is one of youtube nicest places.

    And so Skitchin apparently uses a late EA sound driver which handles multi-PCM and which was also used for FIFA 95 or NBA Live 95. Nice!

    And the track "Smog Dog" is the one I was referring to (@46:25 in the video above). Such an amazing tune, that PSG lead is just that, wonderful!

    I much care about Psygnosis accomplished this smooth rotation effect.

    Real time, animation or another clever trick?

    I'm leaning towards animation because every frame I can spot seems to be a multiple of 22.5º angle (that's 1/16 of a circle). That's still more granurality than the usual 45º mind you. And yeah, animation tends to work just fine for things that are constantly spinning (at least as long as they don't spin too slowly). Things that may need to point at specific angles like the car in that racing game video or a weapon trying to aim at you are more problematic.

    Also dissecting the split screen in Herzog Zwei:



    Red = plane A
    Green = plane B
    Blue = window
    Purple = sprites

    I'm not sure if it's using transparent tiles in the window plane to hide plane A in the right side of the screen or if it's manually clearing and drawing tiles at the split point (because that split bar is wide at 32px).

    I'd love to see someone perform a writeup on how SMS/GG Road Rash's renderer works.

    I simply don't understand how it could work so quickly in my head. I've never bothered to bust open the game in some sort of a debugger, however.

    I thought the lens flare was just a bunch of dithered sprites moving at the right angle, but you are right, they are also using highlight.

    I took a check in exodus, it seems like the title screen has the logo text and the circle being transparent, behind it you see a bunch of circles moving around to simulate the rotated lines, and behind those you have plane B empty and just flashing colours to make stuff like the vectorman text shiny. You also have parallelogram sprites moving on the text to give it a metallic shine.

    I still don't get how the colours of the background get inverted so smoothly. It looks like all of that plane gets updated, so it's no raster fx nor any palette loop... does it update the tiles on a pixel by pixel basis? That's insane stuff.

    The whole title screen is just packed full with so many effects, plus the graphics are stylish and little details like the palette inversion fit perfectly. They partition the graphics so the part inside the circle updates differently than the ones outside, and even put some stuff in the same colour to "hide" them. It's just insane, I can't imagine how they could have designed this animation.

    edit: oh, also: the intro that explains the storyline, it has each picture made up of 2 layers to increase the palette count of each picture.

    OK, back to this :​v

    Due to the way tiles are arranged within a sprite, manipulating the sprite width is effectively chopping the sprite (you may need to also adjust the tile ID depending which side you're chopping). This could be convenient for vertical split screen or other similar effects, since it lets you reuse the sprite graphic as-is with little effort. This doesn't work with the height (since changing it will rearrange the tiles).

    The spheres in the last level of Earthworm Jim 2 (20:03 in the video)



    Let's dissect it:





    Plane B has a few circles that peek through the gaps in plane A. It just scrolls around to animate it, the interesting part of the effect comes from the resulting moire pattern between the gaps and the circles. Nice one there.

    I did some tests with line scrolling effect:

    Pier Solar has this nice background rotation segment. It's not 60 fps or full screen, but still a nice feature:

    Hey Sik!

    Can you analise this rotational effect in Genny Earnest Evans?

    If it's prerendered, it would only require frames for a 1/4 rotation of half of it, as the rest could use mirroring of those frames.
