*UPDATES* - The PAL / NTSC Section is somewhat lacking and a bit inaccurate. See the many liked comments below for more details. - Many games were specifically coded for PAL, mostly to fix music timing (thanks @Strobo) - Pattern tables contain 4KB of data not 64KB of data. I forgot to divide by 8 when calculating (thanks @HughGenuts)

Many games were made for one standard or another in terms of their graphics, too. The different resolutions resulted in different pixel proportions when made to fit in 4:3 aspect ratio images, so images that were made for one standard will be distorted in the other.

@@CarbonRollerCaco This reminds me of Toy Story on SNES - developed by Traveler's Tales in Europe, the game uses a PAL aspect ratio, despite appearing to be properly adapted for NTSC as far as framerate and timing are concerned. Considering the importance of the film (being a technical marvel and the first of it's kind) I'm kind of surprised Disney/Pixar let that detail go. But it works out nicely because the PAL aspect ratio (what is it, 5:3?) fills more of a modern 16:9 display than the old NTSC standard of 4:3.

Making my first NES game, after a week of study and watching your videos, i have managed to draw a heart sprite to the screen. I already had respect for devs of the time, but experiencing it first hand is really starting to put it all into perspective, just how incredible these developers were.

The pattern tables don't each have 64 kilobytes of memory. Each pattern table has 256 tiles, each 8x8 pixels; that's 16384 pixels with 2 bit color depth, or 32768 *bits* in one pattern table. That's 4096 bytes, or 4 kilobytes.

5:15 The map is correct, but the description is wrong. You see, strictly, PAL and NTSC refer only to the color encodings, not the whole systems. After all, analog TV is a monochrome signal first, plus a color subcarrier. So it's more proper to say the US used System M (525-line, 60i) with NTSC color on top, and most of Europe used System B (625-line, 50i) with PAL color on top. And then Brazil used this funky thing called PAL-M, which was System M with PAL color.

I was going to make this comment. As a Brazilian, I never had a problem to import US games to play here. Until I bought my Nintendo 64 in USA. When I rented "Star Wars Racer" for N64, the game was in monochrome, no colors whatsoever. And the weird thing is it was the first game released here with this problem. So it became a lottery and I never understood what was going on, thinking either the game was broken or, more possibly, the console. Rented "Turok 2" and... same thing. But "Banjo Kazooie" played ok, no problem whatsoever. I found out with "International SuperStar Soccer 2000" that the high-resolution mode was causing the problem. With the expansion pack, some games have the option to run in 480i. But with ISS2000, you can barely play in hi-res, so I tested in low-res. BANG: from monochrome to colors! So I was lost, thinking my TV was broken, until I found out about these signal and color subcarrier patterns in the internet.

I'm really glad (and grateful) that you took the time and energy to produce this video, despite the fact that there are already many videos (among other documents) about the same topic. I know some creators have the attitude that you shouldn't do videos on things other channels have already covered. At least sometimes they do. But I'm glad that wasn't the case with this video. I never believed in that philosophy because even if I've seen other videos on NES graphics before, which I have, it's such a complicated and comprehensive subject that there's no way a 20, 30 or even 40 minute video could give you the full picture (sorry for the pun). Even if they did, there's no way a person could memorize everything in it. So it's always great to have multiple resources to consult on the same subject so you can get the same story told from a different perspective, so to speak. Plus that really helps with understanding the material intuitively, as well. If there's something technical in a video or document I don't understand, it always helps a lot to be able to have it explained differently. tl;dr you have an amazing channel that's not afraid to take chances by covering topics others already have. And it's paid off in spades! Thank you for sharing your passion with us.

Pretty crazy how technical the og Nintendo/ famicom is, being a 40 year old console. I watch alot of videos on old school concoles and the awesome shortcuts and hacks they had to pull off with such little ram and processing power. It's ingenuous the shit the devs came up with. Love this channel so far, this is the first video I've seen. I'll have to check some more out.

SECAM NES did actually exist, but it was a pirated clone. Those were popular in ex-USSR in the early 90s. That particular SECAM edition was named Dendy SECAM Classic, if I'm not mistaken, and it was released in 1992. It was a first Russian NES bootleg clone. Subsequent bootleg models of Dendy were PAL only because of two factors, I think. First, multi-system TV sets became much more common by 1994 already. People even modded their old Soviet SECAM-only TVs by soldering PAL decoder. And second, it seems like Dendy SECAM was a failure from a technical POV, lacking reliable color output.

SECAM was partially compatible with PAL, but produced a B&W image when presented with a PAL signal. So these of us growing up in SECAM regions generally were stuck with playing NES (or its clones) without color until multisystem TVs that supported both PAL and SECAM color became common. It wasn't until several years after I first played SMB that I learned that Mario's overalls are red on the NES.

Technically there were mechanical tvs before crts but they were so impractical and uncommon that I wouldn’t argue with anyone who wanted to not count them. So I’ll let it slide.

@NesHacker

Indeed. CRTs are primary focus here as well since the NES was designed to work with them. I wanted to ensure that the viewer had some exposure to the concept if they hadn’t come across it already as it will be somewhat relevant to discussions of timing and VBLANKS if/when I make videos on those topics. But yes, you’re correct, I should have said “For those who don’t know CRTs were the first commercially viable and widespread type of television.”

I see many videos explaining HOW the NES and SNES read and display graphics, but i haven't seen any videos that show the developer process of drawing and programming a level itself. Like, did the devs first make a drawing software that let them save a map info to past into the code? Or did the literally map it out on paper, and then type line by line the code for how the map would be rendered? I really want to see the gritty behind the scenes of old school game dev flow. lol

Hi! i Love your videos and the editing :D Question: I during a project where i want to read sprite data directly from the cartridge, not running the game itself( maybe with a atmega1284p). I quess i can read the pattern tables directly from the character ROM and the pins connected to it. But i need the OAM data to know how the tiles are connected and how many to each sprite and so on. I'm a bit confused on where to find this data? Is it different from each game, or is there a pattern to look for? I think i have seen and read too many tutorials and got a bit confused:b

I remember learning fairly recently that unlike most other systems, the NES’s available colours are ordered by hue and brightness as opposed to RGB. Each palette specifically uses all different hues and brightnesses for each colour to ensure that the sprites read just as clearly on monochrome TVs as colour TVs.

Oh that’s neat, I knew it organized the system palette this way but I didn’t think about the implications for monochrome!

@@NesHacker I’ve developed an interest in how older games and systems used their limitations to their advantage in ways that aren’t obvious, or even become “problems” when emulated on modern hardware. This is one of those examples where now that I know, it stands out when NES style art doesn’t follow that rule lol Another example is how early Nintendo systems rendered frames narrower than TVs, so the displayed frame was stretched. As a result, some developers actually narrowed their art so that things like circles and squares would display as intended. Ironically, first party developers did this the least. Obviously analog signals on CRT screens weren’t as sharp as modern displays, so some sprite work looks much better when a little fuzzier in general. Another way this was utilized was how dithering got blended together and was effectively unnoticeable on intended displays, whereas some people really hate how dithering looks now. Similarly, using vertical stripes (like the waterfalls in Sonic) made them simply appear translucent. The way even relatively newer games utilized resolution was interesting too. I’ve seen people point out funny looking LODs in Mario 64 that were never visible before. PS1 games that used flat image backgrounds like Resident Evil or Final Fantasy were seamless back in the day but look very strange when emulated at higher resolutions now. A lot of games with “low resolution” textures or lower polygon counts did not seem that low when the display was so limited too. Anyhow, I appreciate your reply. That was probably a long read, much of which was either uninteresting or already known, but I get excited sharing lol Hopefully it wasn’t too bad, and if nothing else I’m glad to hear the monochrome compatible palettes were new to you!

NES that were sold in France were PAL versions. TV using the SECAM standards were also compatible with PAL. They were usually described as "PAL/SECAM" TV sets.

0:42 an interesting thing is that some people learn better from top to bottom or from bottom to top, i.e. screen to transistor or transistor to screen. so what you find works the best for you may not work the best for everyone. (though the the way you understand best is often the way you explain best, so nothing wrong with that.)

04:33 Had a very similar TV design back in the USSR when I was a kid. Had a Dendy hooked up to it as well. Which was a bootleg NES copy. Lightgun and all.

Hi! Although you have placed Brazil in the "PAL" category, the analog system used here is PAL-M, it is unique among analogue TV systems in that it combines the 525-line 30 frames-per-second System M with the PAL color encoding system (using very nearly the NTSC color subcarrier frequency), unlike all other countries which pair PAL with 625-line systems and NTSC with 525-line systems.

is there any way to control the frequency of foreground sprites being written to the PPU. For example, could you load one set of 8 eight sprites one cycle and a second set in between to simulate 16 on a single scan line (I assume it would half the frame rate, but I don't quite understand how PPU cycles and frame rate are related)? I'm not quite sure what terms I could search on dev forums to find an answer.

Hi mate just came across your channel really nice content and detail. I got most of the content however, I'm just lost with regard to the attributes I understood how each attribute byte is split into 4 2 bit segments making a byte of data but get lost when "each segment is used to select the palette for 1 of 4 16 by 16 sections of tile data". I can't see the 16 by 16 other than a whole row made up of 8 attributes boxes by 2 tiles ( H or V) across but I just can't marry up the connection I was wondering can you just clarify the above if possible.

Love 64K

Great video I've been nes and snes hacking for years

how are the background tiles moved in subtile increments to render the directional scrolling/sliding? does the 32x30 grid account for single tile overhang or something?

Just to add some more technical information here, when a CRT television is scanning or moving the electron beam, it actually scans every OTHER line first then goes back and fills in the gaps between those.

Hey it's Dragon Warrior i love that game!!!! :D
