Nintendo Virtual Boy

[glad forge]

the vga port of this core only drives a real LED array, sorry

[burnt flame]

Hmm! I wonder if Glenn A. Larson had something with LED stripes back in the 80s...

[glad forge]

@short halo is it possible to make something like adaptive scanlines except in all directions? I'm thinking the brighter the LED is the more it should blur outward perceptually

I was looking at this video recorded on real hardware and the leds make it look not very pixelated

[short halo]

Maybe? Something like this screenshot is not hard. And you would just do the same for horz/vert scaling. Of course you could adjust it to look the way you want in terms of pixels blending into the next pixel or leaving some dark area between pixels. And if you use the right kernel then the pixels would appear pretty round and less square. But a potential sticking point is that the scaler may (I haven't looked at the code in forever) only support adaptive filters on one axis and I think you'd prefer both axes to have the bloom effect.

[glad forge]

I have no idea about the axis

the vb doesnt have much dark space between pixels

it looks pretty solid

[short halo]

Are those background dots single pixels?

[glad forge]

yes

[short halo]

Like red, red, red with no dark pixels between? But when they're bright it looks pretty solid red instead of dots?

[glad forge]

red black red black

this is text on a real unit

= sign is one pixel high

[short halo]

I'm not good at reading vhdl but I think only one axis can be adaptive, which would mean one axis would be fixed sharpness and the other could be adaptive blur based on pixel brightness. https://github.com/MiSTer-devel/NeoGeo_MiSTer/blob/master/sys/ascal.vhd#L2397-L2403

[real hawk]

IF o_v_poly_use_adaptive='1' THEN
    o_poly_lum<=poly_lum(o_v_lum_pix);
    o_a_poly_addr<=o_v_poly_addr;
ELSIF o_h_poly_use_adaptive='1' THEN
    o_poly_lum<=poly_lum(o_h_lum_pix);
    o_a_poly_addr<=to_integer(hfrac3_v);
END IF;

[short halo]

I'll look at some virtual boy screenshots tomorrow and see what we could do. I'll post them in here.

[white gorge]

Just in case it is important: https://github.com/20Enderdude20/Ghidra_v810_v830

[glad forge]

that would be amazing, it would be useful for things like adventurevision too

[glad forge]

I thought this was good real hardware shot for judging the glow

[short halo]

Well it took a bit to fix a bug in the preview app math. edit: and there is still something wrong with the math...

But when I started looking at this, I thought the thing to try would be sharper scaling for darker pixels and softer for brighter pixels. But I'm not sure that looks good.

So then I thought maybe if there was a visible LCD pattern that went away for bright pixels, but I'm also not sure that looks good.

So then I thought maybe the way to go is to average a sharp filter at maybe 70% and then a very soft filter at 30% and maybe it would look like a glow/bloom. And then change the weights for the dark/light filters. But that kinda suck too.

So anyway, I basically gave up for the moment, and just added some filters labeled "Test Filters" to the preview app here https://ghogan42.github.io/MiSTer-Filter-Preview-Page/ and if anyone has some good ideas what might look good they can let me know and I'll try that.

Since there are a million filters in there, you should probably type "test" in the "search filters" box to cut down the number of filters in the dropdown.

[short halo]

I should also add that any blur/glow can only reach 2 pixels (in the prescaled image) away, so the glow distance is limited.

[white gorge]

Matching the visual look of the VB LEDs even on a OLED is hard. The bright red is almost white in its core.

[short halo]

Well blowing the colors out isn't hard, if that's the goal. If the core only outputs red though (I just grabbed a screenshot on google since I've never run the core), a filter wouldn't be able to blow it out to white (or more white) since it can only modify what is there. But if the core would output a color like (255, 32, 32) or whatever than an overbright filter would shift toward white for the brightest colers.

[fossil blaze]

The core isn't only red, you can select from several colors

Even does different colors for each eye in 3d mode

[glad forge]

nonetheless it's really just palettes

just one palette per eye

changing around the color per luma is very easy

now, if you asked me how a human percieves two overlapping brightnesses per eye in the same spot, that I don't know

do they get averaged? is there gain? Is there gain only if it's the dominant eye?

[plucky idol]

Well, the other possibility is that (original) LED output is non-linear.

Here's a generic datasheet that shows that it shouldn't be assumed to be - although how badly non-linear it is depends on how it's being driven.

https://www.farnell.com/datasheets/1498852.pdf

Probably the specs are a lot tighter today than they would have been 30 years ago

[glad forge]

palettes even for lcds are seldom linear in any kind of coherent way

vb is easier because the background is black

the only thing the complicates it is that the lcd's have a halo glow

and i'd argue the intensity of that glow is based on the level of brightness

the filter actually might be more brightening the center of the pixel

[plucky idol]

yeah. It's probably from a plastic layer between the LED and the eye that diffuses it

[glad forge]

it seems like a largely unexplored area of visual effect compared to scanlines et al

[plucky idol]

It will also apply to vector displays

[glad forge]

I suppose, yes

similar

this video someone posted above is really helpful for understanding the details of the drawing and visuals:
https://www.youtube.com/watch?v=jW7M8H99x7Y

the brightness is actually PWM

[plucky idol]

I saw that - they should say, "DPS" not"FPS", but that was a prior discussion

oh ok, PWM would end up more linear I think

[glad forge]

around the 8 minute mark they show it

brightness perception of pwm it seems should be logarithmic

@glad forge doing some research it seems human perception can wash out the color in the center of a pixel as an artifact of how we percieve high intensity red light, so there should be a color drain/intensity increase in the center of the pixel and a halo in the outside, proportional to the level of intensity

and the intensity should be logarithmic

why did I tag myself

I really am overtired

I meant to tag @short halo

[glad forge]

it doesnt help that 660nm doesnt fit inside srgb space

monochromatic sources like this are a good argument for HGIG tone mapping

[glad forge]

im gonna be on vacation for a week, but i've been chipping away at it, some games are almost playable. same deal with wario, I really have to take the time to figure out what I broke there

[short halo]

Probably too blurry?

I do think that maybe the palette could be brighter? When I screenshot the mister, the raw 384x225 png had a max level of (160, 0, 0) with the brightness turned up to 5 as shown.

[glad forge]

it can

so on the vb, there's 4 colors, but theere's also 3 brightness registers for each color

I have it modeled but not as well as it could be

it might be slightly blurry but it's not terrible

I like it

each color is one of four phases, and then the three registers determine the length of each phase

A, B, and then color 3 is A + B + C

so it's like number of phases, and duty cycle

[short halo]

I'll keep playing with them for awhile. The thing is that I keep wanting to make the filter boost brightness, but then if the palette was made brighter then the filter would also have to change. So I should be careful not to do that if the palette is likely to change. But if it's already mostly correct then I could jsut do whatever looks good right now.

So right now with the red palette selected is there a way to compute the max color value the core core produces?

[glad forge]

probably wario

give me a minute, ill see if I can get some of my newer work on brightness into a build for you

[zenith pendant]

Would you like the testing sheet filled out while you are away?

[mint tide]

All this red might be frying your brain, ever see the kenny rogers roasters epsiode of Seinfeld?

[glad forge]

@short halo

revised brightness formula is probably more accurate now

although mario's face looks a little dark there

[glad forge]

there's a reference discrepency on color2 using only BRTB

ill evaluate it later but logically I think it should be BRTA + BRTB

I guess other emulators show it as being kinda dim like that too

medafen probably has the most accurate color representation

well, brightness at least

[short halo]

Here's a few test filters for Virtual Boy. The "V1" filter has more brightness boost for the older Virtual Boy core. The others work better with the new core build from a few posts up. They are also up here https://ghogan42.github.io/MiSTer-Filter-Preview-Page/. Don't take them too seriously, I'm just trying things out. But do let me know if you want something different. I also added a few with an lcd grid in case people like that.

[glad forge]

Awesome. I'm away for a week but I'll try more when I get back

[white gorge]

Man that's a huge improvement. Awesome!

nice speed gains

[buoyant vale]

Does the VB have some type of visible LCD grid?

[glad forge]

It has a strip of LED

And mirrors that oscillate

[buoyant vale]

Right, but do you see spacing between the pixels that would create a grid like that?

[glad forge]

Not much

At very low light you can sometimes see them but there aren't super clear

[buoyant vale]

oh okay

[short halo]

Now that I actually watched (well fast forwarded through) the slow mo video kitrinx posted yesterday I see what it actually does. Since there is a small gap between leds vertically there could potentially be horizontal lines and as it moves horizontally there are 3 phases where it could light up and one where the leds are off, technically there could be space between the vertical columns. But I guess you don't really see much of that in real life.

[glad forge]

The glow tends to hide it

Unlike an LCD

The glow also makes it look less pixelated

But that's the whole project here that soltan has been working on

[buoyant vale]

Yeah the glow is reminiscent of the basic bilinear filtering a lot of emulators and GPUs had

latest version looks better

[buoyant vale]

yeah that sounds like what I'd expect

[glad forge]

That's what soltan is working on the glow works kind of like hybrid scanlines except without the line and in both axis

[glad forge]

yeah this current latest version is more correct, the brightness per level might need some tweeking but it's more fundamentally correct now

[short halo]

According to claude, Because human brightness perception follows a roughly power-law response (the same reason sRGB needs gamma), 50% of the photons does not look 50% as bright. It looks considerably brighter than half — closer to 73% of perceived brightness (since 0.5^(1/2.2) ≈ 0.73). I think this means that the 3.2us would be 0.5^(1/2.2)=0.729 times the full palette color value and the 25% would be 0.25^(1/2.2)=0.5325 times the top palette color value. Does that seem right? I always get things backwards on this stuff.

[kindred jasper]

@glad forge I'm limited in what I can provide since I only have two VB games (Virtual Boy Wario Land and Mario Tennis), but I do have some decent quality camera gear if anything's needed to compare against.

[hushed flume]

Do the nintendo VB Switch thingies do anything fancy, or is it just the bare minimum?

[kindred jasper]

Having worked with a lot of LEDs in the past (and currently rewriting some addressable RGB stuff for a different project), if you want an LED at 50% "perceived" brightness you would PWM it at something closer to 22-23% to gamma-correct it.

Without that gamma correction a 50% LED will appear much brighter than you would expect, the difference between 50% and 100% becomes much less apparent.

[short halo]

Yeah that's what the math says, I guess.

[glad forge]

I was trying to get AI to help me out with the math for that along with the brt registers but I think it's still a little off

Specifically with perception in mind

[fossil blaze]

Bare minimum, the switch can't even detect if it's in one. You can basically try to play the games without the accessory at all, the screen will just be split in two

It's nothing more than a plastic or cardboard depending which version you got holder for the switch with a lens that splits the image into each eye

[spring sphinx]

Wouldn't trust what Claude says since it's so prone to lying.

[kindred jasper]

While I refuse to touch AI for similar reasons, in this particular case (LED perceived brightness) it's not wrong

[short halo]

I mean, I don't know nothing about this. I was just too lazy to think about it and it's easy to get gamma calculations backwards.

[kindred jasper]

Right, the one thing I know off the top of my head is "convert to a float and square it" to get "close enough" (gamma 2.0)

Mostly because I'm using a similar approach in a project of mine to avoid lookup tables

[white wolf]

Huh, golf plays pretty nicely

[glad forge]

floats dont work too well in fpga

I choked on my drink when I saw the price for this

[fossil blaze]

.... Wireless? What?

[charred cobalt]

It has rumble tho

[hazy bough]

This is the better version https://www.retroonyx.com/product-page/nintendo-switch-virtual-boy-wireless-controller I got one to try with your Mister VB core

[white gorge]

Yeah but that is basically the deluxe version and all build by hand/3D printed. You are basically looking at my controller because this was made with my 3D scan as reference/base, then rebuild in CAD. This is also the only wireless with rumble solution that also works on NSO at the moment. Very good quality too.

[orchid reef]

Oh hell nah!

That's enough to buy three Steam Controllers 2!

[sacred grove]

If the bulk of the controller cost is the PCB, then why is the 3D printed and buttons part double the cost of the PCB.

That’s an insane price jump.

“custom carbon fiber shell”

ohhhhhhhhhhhhhh

[hushed flume]

proper or just 3d printed with cf filament?

[buoyant vale]

Thanks just ordered three

[hushed flume]

living on the edge, eh? What if three break? What then?!

[fossil blaze]

Ah yes, the people who made the virtual boy cart with the eink display

And... this

Why exactly do you need a WIRELESS controller for the virtula boy? It's a console you have to almost wear like a VR headset, you aren't going to be sitting on the couch while the console is on the opposite wall

All you are doing is making it cost a lot more while having to worry about batteries and interferance

[wind nest]

I own and like the e-ink cart, but I can't justify wireless for the VB unless you mod it for an external display.

[glad forge]

Maybe a tv mod kit

[gray turret]

If you can find them the original 8bitdo Lite makes for a good alternative virtual boy controller. I tested mine out with the VB NSO service and was able to pull off teleroboxer moves properly.

[lament steeple]

I'm actually trying to get one now, I've ordered it 3 times now, because the first 2 times I was sent the wrong controller, because I don't think anyone actually has this thing in stock anymore

[gray turret]

Looks like ebay is probably the only way and even then they are hard to come by.

80JB is the model number

[kindred jasper]

I have two of these actually! One yellow, one blue. They work great for Virtual Boy and Wonderswan

[gray turret]

Never thought about using it for the wonderswan, thats a great idea.

[fossil blaze]

There was a mod that gave it a VGA port, I think it was called the virtual tap. But as far as I know it's been discontinued and sold out for years now

[clear ledge]

yep someone provided a controller mapping for that so it works well w the mister core

(my only contribution to this whole project lmao)

#1046941428758102086 message

i would be curious how the 8bitdo lite compares with using an n64 controller for VB

[white gorge]

Well, the VB and the WS were invented by the same person 🙂

[clear ledge]

https://tenor.com/view/thats-true-kramer-seinfeld-gif-5503484

[sacred grove]

So the VB core seems to run pretty well now

[kindred jasper]

Funny enough, Castlemania's selling a run of them right now through their "Moddern Castle" offshoot: https://www.modderncastle.com/product-page/virtual-tap-embedded-video-out-board-for-the-nintendo-virtualboy

IIRC all the files are out there, so there's nothing stopping someone from building their own aside from, well, parts and a programmer

[fossil blaze]

And soldering skills

Not everyone can solder 100-pin QIL packages

[hazy bough]

Is this the latest build?

[glad forge]

yes

[hazy bough]

Awesome thanks it’s working great

[glad forge]

I think these are the right direction but the grid might be a little too pronounced at medium brightnesses

[dark parcel]

Looks really good

[glad forge]

I think it's not supposed to have the grid

or at least less

[fossil blaze]

I agree, since it depended on persistance of vision I doubt anyone would have seen any hard lines between the pixels like that

[glad forge]

just in practice you don't because of the glow

[fossil blaze]

Yeah that's what I meant, the virtual boy dosen't really have a screen like a gameboy would so it's going to be a lot more how people saw the image rather than being able to copy a screen's geometry

[mint tide]

the net looks like hearts

[white gorge]

one reason why you do not really see the grid is because the screen size itself is quite small on the real system. The example picture above, if you click on it, it gets enlarged. That is way bigger as you would actually see it.

[white gorge]

if I see this right, the current core uses x3 to display on screen. Use x2 with all black outline and you get closer to what the screen size on a actual screen looks/feels like.

[fossil blaze]

Has anyone put some kind of high-res camera on the VB then to see if the grid is noticable? I know there was a high-framerate camera video recently, but was it also high res? I think usually on those cameras they have to sacrifice resolution for those absurd framerates.

[glad forge]

it's not really about that as much as what you see

perception is what matters, since it's a fixed size screen

you want to make a larger version of what you actually see

[untold remnant]

https://tenor.com/view/seeing-red-unwritten-law-gif-19963751

[white gorge]

you need to look beyond the red.

[fossil blaze]

https://tenor.com/view/dakota-laden-destination-fear-eloise-its-dark-gif-16573107

[glad forge]

with and without the v1 filters

@short halo

I think they have an noticeable impact

that rom (test chamber) has vibration I discovered

made me giggle

it's portal inspired, right up my alley

[short halo]

Nice. I'll still look and see if we can do better. Of course, we are a bit limited because the scaler can only do so much.

[white gorge]

yeah that one is amazing homebrew.

[glad forge]

it's kinda slow to download but it's open so here it is

im sort of wondering how the lines look on the real system

if they blend entirely

that would belie a horizontal blending phenominon

real hardware recording I guess:
https://www.youtube.com/watch?v=u8aCWv88mXs

[fossil blaze]

Hmm, yes, I see...

(Why did Discord attempt to display a binary file as text?)

Wonder how common it was to only display the UI in one eye like Teleroboxer does, I was wondering why I wasn't seeing a UI until I switched which eye was being displayed on screen

[zealous sonnet]

Are you using the latest core build? The newest one should have fixed that.

It should be in both eyes.

[fossil blaze]

Haven't tried Teleroboxer on the newest core yet

[zealous sonnet]

It wasn't just that game that had the issue on the earlier build. Mario Clash for example only had Mario and the enemies appear in the left eye image as well. Either way, it's resolved. It was just a curiosity in that build more than anything.

[sweet girder]

.vb is also Visual Basic sourcecode

[fossil blaze]

I remember it happening on more than one version of the core, but they were all early ones

[fluid compass]

So on the darkness thing - has anyone tried Hyper Fighting? Am finding it impossible to see it, but wondering if that's just a quirk of it being an aftermarket game. (latest version of the core btw)

[glad forge]

im no sure what's up with that game

[gray turret]

It is dark on the real VB, I know from experience

[lavish wren]

MiSTer wins again!

[white gorge]

It appears that everything is one or two "steps" darker as it normaly would be. According to some docs it seems possible to control 128 brightness levels via software. It is possible that the coder of that game has set the brightness lower as standard. It is probably a bit unfortunate. The coder was not seen in years. Not sure if that can be fixed.

[glad forge]

there's 3 bright registers and 4 levels of pixel

how those look is a big equasion

how they look to your eye is even more complex because of how the system displayed

pretty straightfoward

[short halo]

I guess you'd just do this unless you knew something about how long it takes the leds to "turn on" fully. Assuming the target is approximately gamma 2.2 like srgb. ```>> [0 0.25 0.50 1.0].^(1/2.2) * 255
ans =

      0   135.7927   186.0837   255.0000```

[glad forge]

well those values can change

they are settable registers

so it's kinda a messy shift math formula

[short halo]

well that's annoying

[warm panther]

Lucky for you, this is an april fools joke. At some point, Kit is gonna be like "The Aristocats"

[fossil blaze]

Time to purchase a 500,000 FPS camera and point it at the leds of a virtual boy

Also, wow, those things have shot up in price nowadays, I think I paid like $50 for mine, and less for the broken one I use for parts

[lavish wren]

Everybody, everybody, everybody wants to be a cat! 🎵

[zealous sonnet]

I am going through Virtual Boy discussion withdrawals.

So what is everyone's favorite Virtual Boy game (not including aftermarket stuff!) that isn't Wario Land?

Mine is Teleroboxer! Super fun once you understand it's played quite differently from Punch-Out.

[swift holly]

My vote would be Jack Bros and Red Alarm

[wind nest]

Vertical Force, I've always liked the Hudson vertical scrolling shooter games. The dual planes makes it a different sort of challenge, and I find it works well with the 3D effect.

[zealous sonnet]

Vertical Force almost needs the 3D effect. Playing it without it is very difficult!

[wind nest]

The ship size changes, but it does benefit greatly from the efffect.

[white gorge]

This game is also with 3D effect difficult to play.

[kindred jasper]

Adding a vote for Jack Bros

[sacred grove]

RED ALARM

[lavish wren]

Amber alert!!!

[glad forge]

sorry im still working on it, just nothing super exciting to report, and i've been a little busier this week

[glad forge]

those glasses aren't the right color codes for any of the accepted 3d standards

more appropriately they would be cyan and red, or green and magenta

One of my favorite films ever. And a very smart one, too, presenting "investors" as the origin of all modern slavery! Just they are presented as "investors from outer space" 😄

[fossil blaze]

What about interesting homebrew? Everyone knows the retail games... since.. there was't many of them. Was trying out a game called Elevated Speed, was like F-Zero with a pretty good framerate

Didn't try it out in 3D yet, curious how well the effect works on that

Nice! Vertical Force is like a Star Soldier or Blazing Lazers type game.

[white gorge]

unfortunately Vertical Force is not very good playable. Playing a shooter like this needs focus and this is something you loose very fast in that game.

[agile anchor]

The new game (not released previously) is not in this batch I don't recall his named ?

[white gorge]

zero racer and dragon hopper

[fossil blaze]

Still waiting for those, I'm guessing they're planning to release them last

Only ones I'm really interested and honestly since I played all the others long ago

Surprised Bound High isn't also on the list

[wind nest]

The main difference is keeping track of an upper and lower plane, using the perspective hints to determine whether something's higher or lower. I consider it as playable as anything else Hudson made.

[white gorge]

yeah I am worried they keep booth for last. 🙁

[hazy bough]

If only we can play the Switch2 virtual boy in dock mode

[white gorge]

the gameplay is not the problem. Keeping track is hard because it is red black, the almost needed 3d and it just has that few colors. It is very busy on the screen. I like the VB but I think games on it should not be so busy or if they are, it should be clearly visible to comfort the eye.

[wind nest]

I honestly don't see it as unplayable. I've mostly played it on an actual Virtual Boy, but bringing it up in the core it plays fine too. Seeing the perspective hints is critical to playing the game, but it's just brightness and sprite size for the most part.

[white gorge]

I did not say unplayable but not very good playable compared for example with Soldier Blade or Final Soldier. But that is just my opinion 🙂

[wind nest]

Absolutely valid, I'm offering my opinions as well. I liked it enough to buy the cartridge, but I could understand that not everyone would enjoy it.

[white gorge]

I once had a full VB collection. Now I still own almost all JP titles. Vertical Force is not bad. But if the VB would have lifed longer, I am sure other SHMUPS would have made things differently. I experiment with R-Type myself.

[wind nest]

Probably. I felt Hudson's attempt at expanding their shooting game lineup to a console with the ability to display 3D perspective was kind of neat, even if it isn't perfect. I wonder how well a horizontal scroller would work with multiple planes?

[white gorge]

you can get a glimps here:

[wind nest]

It looks good, how would you see adding depth (as in planes) to the gameplay? Or just using the 3D more for visual pop?

[white gorge]

Your question just gave me a quite unique idea 😄 But to answer the question, I think this depends on the game/level and what is possible. Visual pop is always a option but having something for the gameplay is always good.

[median turtle]

[feral storm]

I quickly analyzed the files from the last update on NSO, nothing new concerning the game files, as all are already with known public hashes & other values.

[nimble rampart]

They likely downloaded them from the same sources we do so that makes sense

[white gorge]

the Hashes and stuff are the same because the rom is the same for these games. But this does not mean that N is taking roms from the Internet.

[fossil blaze]

Exactly. I remember a few years ago when several sites were running the story that Nintendo just downloaded a rom of Super Mario Bros for sale on the eshop, the "smoking gun" was the header... despite the fact that nintendo had licensed the ines header. I have a rom dumper and used it to dump most of my snes, n64, and gba games, and the CRCs for them all matched the public dumps.

[mint tide]

licensed from who exactly?

[feral storm]

There's a lot of confusion surrounding all of this, and I can explain what happened, having discussed it with Cifaldi at the time, and also since then with the team in charge of the NES emulator for the Wii.

What happened was that we found a header marked DISKDUDE! on ROM files contained in two games. This signature came from ROM files shared by a group, and it ended up in a GoodNES set from that era.

The contracted external team in charge didn't receive the ROM files (from the internal section at Kyoto) in time for validation and final packaging before sending them to an internal Nintendo service for signature. So they rushed to grab a ROM from the internet, using whatever they had on hand.

Cifaldi turned this into Nintendo downloading ROMs from the internet, etc., during a GDC conference on preservation (long before he founded the Video Game History Foundation with a few others).

But he apologized the following year and provided clarifications after knowing at least some more of these infos back then, which were not widely accepted by the public.

Regarding Kawase, yes, he worked on iNES at the time, on the sound portion of the Famicom. He was later hired by Nintendo, initially in development (for Doubutsu no Mori / Animal Crossing), but in recent years he has been Head of an Internal Digital Archives department, in a Kyoto branch.

We had found traces of emails and references concerning him, during the backups of the Famicom Disk System games, and the loss of the Zelda master disk, where it was necessary to recreate one from a decompilation of a cartridge for Famicom Disk Writer (kiosks for the shops in the 80s).

No iNES involvement or license here.

[fossil blaze]

So Mario Bros was downloaded off the internet?

[feral storm]

Yes, but not by Nintendo. It was an external contractor who did it.

[fossil blaze]

Ah

So Nintendo did end up using a rom downloaded from the internet then even though they didn't do it personally

You would think CRC checks would have shown that it was not a clean dump but one that had a group's name in the header

(I assume if you dumped that game from a cart yourself that name would not be in the header)

Modern sets I assume don't have that in the header anymore?

[feral storm]

These older headers with watermarks have been obsolete for at least 15 years, following large-scale dump campaigns organized by public groups and the advent of modern open-source dumpers.

These values ​​have been definitively established and once again verified since Nintendo's internal lists were leaked, containing all the information, including the CRC32 values ​​of the masters they keep internally.

This even made it possible to discover variants or revisions of games that had never been dumped.

[fossil blaze]

You mean from the gigaleak?

[feral storm]

Yes.

[nimble rampart]

I know, I was making a funny because... Nintendo

[sacred grove]

lol Cifaldi

[feral storm]

You know it, I know it.

[zealous sonnet]

Didn't know the core had save states?

[warm panther]

I think areku meant to post this in the game gear channel

[dry loom]

My bad... I meant to post it in the NES channel... 🤦‍♂️

[zealous sonnet]

No forgiveness.

[clear ledge]

say three hail robbys at morning and night for a week and don't do it again

[dry loom]

A week? That's too much... 😩

[sacred grove]

I literally re-upped for the Nintendo Expansion pass just because of Virtual Boy

[spark mountain]

Haha same. Just did it yesterday

[sacred grove]

I did it today!

[zealous sonnet]

I shall be patient and wait for the core to be finished!

[fossil blaze]

I'm just interested in those two never released games

[sacred grove]

@glad forge hey, Nintendo put out an article today that explained how the Virtual Boy displayed visuals

Virtual Boy™ – Nintendo Classics - The What, How and Why of Virtual Boy - How are the Visuals Displayed?

I hope that helps with the core

[glad forge]

I know how

[mint tide]

That’s the next part

[pastel venture]

can i look at nintendo today tomorrow?

[pallid grotto]

Katrinx are you planning on launching core with swappable palette or is it stock red? Is there any value (comfort) in that?

I assume it's not as harsh vs the real VB. I also haven't checked out how Nintendo is doing it on NSO yet

[glad forge]

probably red and 3d colors

it's not as simple as just a palette

like it can be "a color" but the actual levels of brightness are a lot

it's not just 4 colors like you might think at first

[sacred grove]

How many times the LEDs stay on

[glad forge]

pulse width modulation

4x boolean phases and a number of variable durations

[sage helm]

Why did they do this

[covert pasture]

Just want to say thank you again for this. Its the core I've been most looking forward to (apart from save states added to cores)

[glad forge]

it's coming along

the cpu feels pretty solid now

vip needs more optimizing

[zealous sonnet]

Agreed. Love that we're finally getting a Virtual Boy core. Looking forward to testing out the next build.

[formal cloud]

Wait, it's actually for real, this time???

[zealous sonnet]

Always has been real!

[formal cloud]

No, actually. Like, I can't tell what is or isn't a joke anymore. Is this actually happening?????

[untold remnant]

Yes, Kit is working on it

[formal cloud]

YESSSSSSS

[glad forge]

no it's a trick

[spark mountain]

Haha I thought it was a trick because it came out on April Fools Day…but its actually real!!! 😁
