Introduction
The purpose of this thread is to share high-quality sprite images, that depict accurately what objects look like in game, and where the image is displayed in relation to the sprite (box) location.

Nice to have this thread here too. Those images could definitely be useful to CoinKiller.

Unfortunatly the new guidelines require a video capture card, or equivalent - so specific frames can be picked out.

If we can get NSMB2 to run in Citra, there's always that, I guess.


The challenge is properly separating the sprite image from its background though, which can be tricky with non-straight borders.

Citra would be fine, as long as it is accurate.

That's easy if you put one of those SMB3-styled colour blocks behind the sprite, and as long as it doesn't blend into the background. Examples of objects that blend into the background: Fire Snakes - which will have to be just an outline until a better way is found, and Beanstalks - which are okay because they are 2D so can be ripped from the files.
And after that all you need to do is remove the colour with an image editor that supports transparency. I use Paint.NET.

Good news. I am receiving a 3DS Capture Card in about 3-4 months. I should be able to make sprite images in accordance to your guidelines, Hiccup.

Very good news! Sorry about the strict guidelines, I just wanted the images to be consistent.

Oh, of course. Once I receive the capture card, I will be more than happy to get those sprite pictures.

Know what'd be the best? Some hack to force the game to render sprites separately and send them to a dump, with transparency preserved.


But of course that's a completely different thing difficulty wise.

That sounds.. interesting. Would it be possible?

Would definitely require ASM hacking. Or somehow probing into the GPU to dump what's being rendered.

That would be better as it sounds, but until then perhaps I could take screenshots of the game when everything is frozen at startup for like a mere second. Do you know what I mean? That way, I can put sprites near Mario and screenshot it on boot up so that they are in the original position.

That's a good idea. Maybe you can also place them against a fixed-color background (basically removing the background). It'd make it easier to recover the transparency on the borders.



The best, but dunno if it's possible: take a snapshot of the sprite against a fixed background of one color, then another identical snapshot against another color. That way we could completely recover transparency by looking at the differences between the two (and writing some good code to do that).

What about the black background used in the final course of the Gold Classic Pack?

Can work I guess.


What happens if you specify no background or an invalid background for a level?

You can't change the background, as of now.

The middle tiles of the coloured blocks in the grassland tileset are solid colour. And the light green one is a great colour to use.

Ooooh, that's a good idea! I didn't think of it.
