what does snes stand for This is a topic that many people are looking for. bluevelvetrestaurant.com is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, bluevelvetrestaurant.com would like to introduce to you Graphics & Palettes – Super Nintendo Entertainment System Features Pt. 01. Following along are instructions in the video below:
“Video is part 1 in a series about super nnintendo entertainment system features. We ll ll be introducing the various graphics nformats as well as palettes and how they are to assign colors to the graphics. Suppose we have an image that we want to store non our console how can we represent this 2 dimensional image nas a 1 dimensional stream of bits. We know we can divide our image up into pixels nand that each pixel has a single color or it s transparent for now.
We ll just treat transparency as its nown special color. Let s start at the top left work across nand down listing off the colors of each pixel. Then we can represent each color as a single nnumber by finding the appropriate amount of red green and blue in the color for reasons you ll find out later. We treat neach color as a 5 bit number ranging from 0 to 31.
If we do this for each pixel. We ll end up nwith 512 bytes that correspond to an approximation of this image. I say approximation because we may have lost nsome color data when we limited our color space from 0 255 to 0 31. But this works we can retrieve our image by just reversing nthe process.
Going from a byte stream to a 2 dimensional image as long as we know what nthe size of our original image is what we have done here is called direct color the graphics data holds the color of each npixel within it without having to do any extra work. The only problem is that this file. We made nis very large you can tell just by looking at it that there nis a lot of repetition since we use the same colors. A lot maybe instead of storing.
The color of each npixel in the file. We store which color. It is and then make a list of all the colors nto reference we ll call transparency 0. Black 1 white n 2.
And so on separately we ll keep track of which color nis..
Which number without it we wouldn t be able to restore nthe correct colors of the image. This is called indirect color and it s nwhat most of the snes graphics formats use another benefit to this format is that we ncan switch our color table the palette and create a copy of the graphics with a different ncolor scheme to learn how the data is truly stored in memory nlet s use a more simpler image for now. This image has only two colors black and nwhite. So our color indices are just 0.
And 1. This is already in binary. So we just start nat. The top left work our way across and down to form our file.
We used 1 bit to encode each pixel so we nsay that this file has a depth of 1 bit per pixel or 1bpp if we step up to 2 bits per pixel we find nthat we can expand our palette to be 4 colors intead of 2 and our indices run from 0 3. This is the lowest depth that the snes supports nand it always treats color 0. As transparent. But there s a small catch the two bits per pixel are not stored togetherin nmemory.
There s this thing you have to keep in mind nthat s called a bitplane. The nth bitplane is the nth bit of each index nfor each pixel. So the first bitplane is the least significant nof each index and the second bitplane is the most significant bit to store this image in the snes s 2bpp format. Nwe take the first bitplane then the second bitplane of each row.
Then we add on each row. Until we get to the nlast row. There are other ways to store graphics in na 2bpp format. But this is just how the snes interprets graphics.
The next depth the snes reads is 4bpp this allows for 16 colors since each pixel nuses a 4 bit index we interleave the first and second bitplanes nlike..
We did for the 2bpp image. Then we interleave the third and fourth bitplanes. We can also continue this pattern for 8bpp nimages. Which allow for 256 colors there s another 8bpp format.
The snes recognizes nused with mode. 7 graphics 8 bits per pixel is just 1 byte per pixel nso. We can just store the pixel indices directly one after the other this makes more intuitive sense. But it isn t nreally expandable.
Which is why the other formats. Don t use this method. 8bpp graphics. Can also be stored in direct ncolor format when a certain switch is set the downfall to using direct color is that nyou are limited to an 8 bit or an 11 bit color space instead of a 15 bit color space.
We did all these examples with an 8×8 pixel ntile. But what if we had more graphics than that 8×8 tiles are stored one after the other ntwo tiles will never combine or interleave data. Generally tiles are organized in rows of n16 due to how objects and 16×16 characters work. But you can really interpret the data nhowever.
It applies to the situation. So now we know how the graphics are stored nbut. We still have the color data to deal with you ll notice the highest color depth supported nup to 256. Simultaneous colors that just happens to be how many colors.
The nsnes can hold in its cgram at one time the colors are stored in the same 15 bit format ni showed earlier a palette is the sequence of colors used to ncolor in a particular graphic..
According to the color indices palettes can be 4 16 or 256 colors depending non. The bit depth of the graphics themselves the first color of the palette is always treated nas transparent and can t be changed. Even if the tile doesn t have any transparency. The first color in cgram color.
00 is used nas the background color behind everything so now given a dump of cgram. Which holds nall the colors and a dump of vram. Which holds all the graphics. You should be able nto figure out what the graphics look like you can use an emulator s debug tools.
Such nas bizhawk or no sns to look at the ram and graphical representations of the ram in real ntime. If you are curious thank you for watching this series of videos aims to introduce various nthings and explain them on a basic level. There are a lot of details that may not find ntheir way into these videos so i encourage you to do more research on your own if you nare seriously interesting in this sort of stuff. to save money i don t know but it s got similar locations and carice van hooten who played the red witch in game of thrones she stars in this as well in a not dissimilar role.
I ll say that but it actually revolves around the plague and its origins and there s a supernatural factor and swords and armor and mud and caves. And you know it s again it s not the best one in the list. But it s it s solid. But it is the closest thing to game of thrones you re gonna get without it actually being in the real thing and number one for me i had to go with the best movie that i was able to put on this list that i think qualifies and while it s not as similar to game of thrones as black death.
The one i just mentioned braveheart is a solid choice. If you just are going through game of thrones withdrawals. It s got a lot of similar elements obviously it takes place in our real history. Not in an alternate history.
But that aside it s gonna feed the fire it looks and feels like it takes place like in the north..
So that that sort of vibe does a lot of what you get from it and most of you who ve seen this this is one of those movies that very very few people. When you ask them have not seen it. Unless you re younger or just now old enough to maybe see it it s great. I can t say too much more about it.
But i ve wanted to include it one because it is the best one i could come up with as far as its acclaim not necessarily its similarity. But it s a claim and i think it s similar enough to satisfy again to scratch that game of thrones itch. So please let me know what you thought of this list. If you think i m just crazy for including some of these things and they belong nowhere near game of thrones.
Let me know in the comments. If you ve got other recommendations. Please let us know because people will read these comments and these recommendations will help them as they re going through this this very difficult time and they re they re really there last year. Without game of thrones before it s finally over so thanks for watching likes comment.
Subscribers are always appreciated and in fact if you want to win that deck of cards. I told you about the deck with these cool designs on it see if you can see someone there s just like a rabbit. All the jacks are a different version of jack nicholson. So that s kind of cool.
You know i m excited about these this is my deck. So i m gonna send the winner a brand new there s the warriors. I m gonna send the winner a brand new deck even the back school it s got like guns and all kinds of stuff on it so if you want to win that deck just be a current subscriber and comment and the top comment after four weeks. I m gonna reach out to you directly and get your address and ship you your own deck of cards so thanks for watching and you will see me next time ” .
