N64 Tutorial: Disable N64 Nintendo 64 Anti-Aliasing/Blur for Sharper Image WITHOUT OSSC & ultraHDMI 

Interesting that this was effectively an options that developers could've switched on or off, but its seems that nobody ever went for it.

This has been suuuper helpful...thanks Wobbling Pixels, and thanks Velby.

On a crt these games look really good. Hd tvs show everything that you never were supposed to see the n64 is a hard system to bring up to date. Sucks cause its my fav console.

A lot of these games don't seem to look like they were made for 0 anti-aliasing in mind, like idk the fact that there is heavy dithering says something, and this is coming from someone that quite likes PS1 dithering. The dithering here just looks like a way to create more colors when a heavy blur is added to the image.

I have recently been playing with these patches (NTSC N64, RGB bypass mod, RGB SCART lead, CRT, Everdrive) and the difference between having AA on or off is visible in many of the games with 3D geometry. The N64's AA algorithm is pretty low quality, especially in combination with the low resolution. Did you notice the top and bottom line glitching (black pixels) in the Super Mario 64 clip in this video? That's present in the game as released and is the algorithm deciding that the border takes precedence over the game image where polygon geometry collides with it! Ultimately, it generally comes down to YMMV and personal taste. Some games look better with AA disabled and some look worse for various reasons (e.g. all of Tamagotchi World's flat objects have a blue outline around them for some odd reason, which is largely masked with AA turned on). Some games, such as Gauntlet Legends, don't have AA enabled in their retail form, which is an interesting developer choice, don't you think? Perhaps because it looked bad enabled and they decided against it? What I do wonder is if we get some frames back on real hardware by disabling AA. It isn't apparent from your video, but that may be down to system used, capture and render methods, etc., so we may not be able to determine it by watching this footage.

AA is one part of the blur, i been working on patching for both this sand the IV blur but freaking jet force gemini will only do the noAA patch app because the only way i seem to be able to IV deblur is through patching with a gameshark code and while it looks great for one minute it always quickly crashes :/

Body harvest work in anti-aliasing off?

That is not antialiasing. wtf was Nintendo even thinking, that's extreme blur!

This is such a great comparison that clearly shows the pros and the cons. It softens edges and gets rid of banding and chekerboarding on solid colors, but at the cost of MASSIVE loss of finer details on fine lines like the soccer jerseys and textures details in scenery and distance. Anti aliasing? Nah, more like cataract simulator. P.S. What game is that at 4:30..? I don't recognize it but it is giving me Metroid Prime vibes.

Hello. I can't find 007 The World is not enough AA code. Can you help me?

Now if someone could figure out how to get rid of or disable the dithering on most games in an attempt to get the console to look more "emulator" like, I think we would have a home run! The massive amount of triangular shaped dithering on games like Star Fox makes it unpayable on an hdtv, and with the ultra HDMI installed, it makes the dithering look even worse!

Great tool! Are there games it doesn't work with? Seems like some games I sue it and get the patched rom, other times it doesn't appear to do anything.

Thanks for the hard work! A while back I wrote down some of the codes from Assembler Games and put them in a Google Drive: drive.google.com/drive/folders/1unUffkR6NIjBNM8vaHKE-vLBFAMmibwW There may be codes I've missed to write down, and not every code has been tested!

Thanks man. The original links are all dead, and it's harder to find the original files for this stuff. I did find a Reddit thread with a link to the program through Internet Archive, but this is much easier, so I liked and saved this video. I still have a question though. When you read the read me file that goes with the program it mentions some other stuff that could be tweaked. Probably nothing you should mess with. Still, I would like to know how you could though. How do you even get to the "filter options" mentioned in the "usage" part of the read me file?...

3 point filter is disabled, not just the AA

FXAA this filter is not... though I guess FXAA or MLAA or SMAA also add some blur. I wonder what the main purpose of this filter that is being disabled here was... certainly does provide anti-aliasing in some instances but even more than removing aliasing this filter is removing dithering. I think they developed this filter to remove dithering patterns first and foremost and AA effect is side effect, even if they later realized it does also masks aliasing.

Left looks better. Just upscale it in an emulator if you want it sharper

Thank you brother! using this along side my cheap hdmi adapter i am getting ultrahdmi levels of image quality! This is single handedly the biggest image improvement you can get for n64. booting up DK64 and mario kart after this patch was mind blowing!

Does the footage also have the de-blur enabled? From RGB or ultrahdmi?

Thx for tips Finally n64 games look like ps1 games on my crt:)

Looks like it's a matter of personal preference. Some games look better with the patch, while others (namely Star Fox 64) are better as-is.

it's almost like seeing all those N64 titles running on a PS1 lol

The fact that n64 games could have been sharper is really annoying. Developers should have given players the choice to switch off the AA

Thank you for making this video. Honestly the differences are minimal. AA off exposes the dithering. N64 was a mess.

I don’t why people insist that turning blur off in these games make them look better. At least the antialiasing made the games have less of that hard edge pixelated shimmer

Can you give us a pack of rom?

Idk if it's cope or not, but I prefer the look of the anti aliasing. I hate the look of dithering, and some games are a bit too sharp on the edges.

The video title is misleading. "Anti-aliasing" and "blur" are two separate issues on the N64, and this only affects the former.

I was jamming out to the diddy Kong racing title screen
