How Graphics worked on the Nintendo Game Boy Color | MVG

[@CodaBroda]

Love that you added how GBC was able to “upgrade” older games with color! That was a mystery of mine as a kid; very cool they had a master list to retroactively set the color palettes.

[@WindowsXPFrog]

CodaBroda same, it blew my little mind.

[@leojei]

Same here, exactly why I watch this video in the first place. The default colour list is a genius move on Nintendo and game dev part, making old game cartridges work as-is w the new hardware w colour.

[@BlazeHN]

I opened this video just because I wanted to know that, for example how the new Gameboy Color knew the old Super Mario Land 2 Mushroom had to be red and white for example.

[@leojei]

@César Leiva me too. Preset color palette by Nintendo is actually a clever implementation.

[@TtEL]

I guess not the GBA, He showed Link's Awakening (the original, not the remake) running on the GBC and it doesn't look the same as me running it on my GBA. At least running it on my AGB-001, I have not tried it on my AGS-001 SP.

[@ModernVintageGamer]

A Few corrections : 1:10 - Xekkusu is actually titled X or X (エックス, Ekkusu) in Japan. 7:30 - Technically VBlank occurs at any scan-line above 144. 9:26 - Hi Color mode can display around 2000 colors instead of 4000

[@MarcoGPUtuber]

MVG, I have access to both a Wii and a PSP devkit. If you're interested, hit me up. Gear Seekers knows me.

[@KoenHendriks]

What i found out on Mario Island 2 - 6 Golden Coins is that on the boot of the gameboy you can override the color pallet by holding the B button and using the D-pad. You can even chose the original 'black and white'

[@dan_loup]

The DMA unit on the gameboy color can also copy data from the cart to the video ram VERY FAST, like 4MB/s, it's a massive upgrade over the 100KB/s if lucky you had on the original gameboy and it's what allows it to play FMVs etc.. the DMA on the original gameboy was fixed on the task of copying sprite parameters from the memory to the sprite memory so you could not use it to do things such as copying tiles to the vram.

[@mrverybored]

You're really over-stating the CPU speed - according to the GBC dev manual the CPU is 1.05mhz in normal mode, and 2.10mhz in GBC/double-speed mode... a quarter of the speed stated in the video.Makes some of those effects achieved look even more impressive :)

[@dan_loup]

​@@mrveryboredIt's a bit more complicated. The gameboy CPU execute one instruction every 4 cycles, so they're dividing the clock on the manual due that. And there are instructions that takes more cycles, but on the gameboy CPU i think it rounds to multiples of 4.

[@jwilder47]

I'd always wondered how my GB color was able to colorize my older games.

[@Ned47628]

Some of the later original game boy games had colour graphics in their code for use with the Super Gameboy

[@Smetroretro]

[@sapiense-science-cerveau]

If I remember right you were also able to change the colour palette assigned to GB game by holding the D-pad in a direction while booting. (Or maybe it was only on GBA, not 100% sure... But I used this trick a lot to change my Tetris experience)

[@Zuudo]

8:13 nice T-Spin

[@AttilaTheHun333333]

Would have bern nice to show the real screen of the GBC more often. People get the wrong impression it was this contrasty and colorful on the original Hardware.

[@HCkev]

Some emulators can emulate the "washed out colors" look of the GBC screen

Thank you for putting these together. I know you’re putting a ton of effort into these and I don’t know how you find the time.

[@poptheweasel100]

Game Boy Color is probably my favorite Nintendo handheld. It's weird, it's rather overlooked, the library is decent at first glance, but when you start searching for the unknown games, like Bootlegs and cancelled games, I swear, you'll never find a more underrated handheld. Some of my favorites include: Zook Hero Z, a fantastic Mega Man bootleg that combines Classic gameplay with MMX style movement, it's fairly long for a GBC game, has great level design, fantastic soundtrack using Capcom's soundfonts, and is a joy to play. Infinity also comes to mind, a cancelled GBC RPG that had SO much potential, being made by RPG lovers, with sound engineering by Mathew Valente, the composer for Chrono Resurrection. The battle system is unique, the story is surprisingly detailed, there's quite a lot of lore, and even the source code is available online, so hey, if you wanna work on a GBC game, give it a shot! There are plenty of other bootlegs as well that are awesome, like Pocket Monster Saphire, a good strategy RPG with horribly mistranslated Pokemon, Fire Emblem GBC, a decent if slow Fire Emblem game, and even a few decent RPGs, if you can read Chinese, that is. I'll also mention Mythri, which like Infinity, is a RPG with a demo, but it isn't that good standalone. The story was pretty good for its time, and you can read about it online somewhere. But with all these games, there are still some fantastic ones out there. Handheld Underground has all the bootlegs you'd want, while the cancelled games can be found by typing their name and GBC. I love these games and I want more people to love them, so I'm spreading the word!

[@terraspent]

ty for the insight, i think a gameboy color just may be my next direction for a new addition to my collection.

[@HieiTF76]

My only regret is that they made Link's Awakening DX backward compatible, which seems to have limited the colors they used (gameboy color games only always have better colors than backward compatible games), which felt average.

[@Pr0f3_YT]

overlooked?!? under rated handheld?!?! what universe are you living in. the GBC is the most popular model next to the SP. it came back into the modding scene in a huge way. there are hundreds if not thousands of dedicated communities, modders and collectors under rated?!?! HAHAHAHA 😂😂

[@Pr0f3_YT]

under rated handheld is a Sony Vita

That edit at around 5:40 is unbelievably clean - it's insane that you reach a level of quality like this every single week!

[@MousePounder]

Every one of these videos is simply fantastic. Thanks MVG for all the hard work!

[@faustianblur1798]

Horizontal Blank interrupts were the key to getting that classic Mode 7 perspective on SNES too. Mode 7 allowed the SNES to apply transformations like scale, skew and rotation to a 2D image, but by scaling each horizontal line separately developers could make it appear as if the image was shrinking as it receded into the distance (up the screen). It seems in implementing H-Blank on the GBC, Nintendo enabled the same effect (minus the arbitrary skew and rotation).

[@BrianM180]

It's really fascinating how much you can get out of the Gameboys. Recently I tried out the Resident Evil prototype on the GBC and was quite suprised at how well it captured the original style of the game.

[@r35.]

Watching vids of 1990's tech in 2020... I never imagined this 'future' back then lol

[@overlordalfredo]

Hamtaro Ham-Hams unite is one great example of what the GBC was capable of. That game looks like a cute little GBA game, but it is from the GBC Era and also runs without any slowdowns at all! Such a good system!

[@sawbonesquad4876]

The first gaming system ever bought for me. Nostalgic. The GBC had a lot of good exclusives, sad it was short lived due to the GBA.

[@jwr2904]

Same here, got mine in Dandelion yellow with Pokemon yellow. Good times lol

[@SirCharles.]

@@jwr2904 I got mine in the translucent Atomic Purple with Pokemon Yellow. I still have the GBC but unfortunately lost that cartridge somewhere. Good times indeed!

[@davidoros3268]

One of my favorite aspects of the GBC was being able to change the palette that the system used for GB games. Playing Pokémon Blue with negative colors (is that right?) or switching from just blue to a blu-ish green was awesome. I feel like not many people know about it and while it was kind of mentioned in the video it would have been cool to see it displayed. You switched the color palette by pressing directional buttons or directional and A or B while on the “Game Boy” screen.

[@HomeAmatuerRacer]

David Oros OG night mode

[@joemck85]

Speaking of, the pink/blue pastel palette option is useful in Pokemon Red/Blue to get through Rock Tunnel without Flash. The game turns 3 of the background colors into black and the 4th into dark gray, and all the sprite colors to black. Picking the pastel palette made that dark gray a pale blue. You still can't see NPCs but you can see the walls easily. This trick wasn't possible in Yellow since it sets GBC palettes, but it wasn't needed either since you could just talk to Pikachu to illuminate the screen for a moment with its sparks.

[@davidwells6259]

This was a really interesting video. MVG videos always are really informative. It's cool what was possible on old systems because of the ingenuity of the hardware engineers and the programmers.

It's incredible what they were able to do with the Gameboy and GB Color. Looking back at retro game hardware/software development you can really feel that they were pushing the boundaries, using creativity and ingenuity to work around the limitations of the time. Feels good to learn about the tech behind this little handheld console that fueled my childhood. Awesome video!

[@Kafei2006]

Toki Tori on GBC simulates prallax scrolling. Here's what Collin Van Ginkel of Two Tribes BV told me about how they achieved this (this here is a direct quote, not my words): "The multilayer scrolling is actually faked by having a 'video' of a scrolling 64x64 pixel pattern stored in ROM that's being streamed every frame. If I remember correctly, this is also where most of our ROM size went to. The rest of the game was really tiny and Nintendo didn't have any smaller cartridges, so we thought we'd just use it for that then."

[@miguelmejia4656]

it's not fake if it's shown perfectly on the screen. it's still considered a side scroller.

[@Kafei2006]

Those are the words of the actual dev, not mine. If you think you know better than the dev itself...

AMAZING !!! Next ? : How Graphics worked on the Nintendo Game Boy Advance ? Can you please talk about the (software based) 3D capabilities of the console ? I need to know if some games like Street Racing Syndicate for GBA are in true 3D or not.

[@NYCJoeBlack]

Alessandro Cussino - Yes, please do the same for the Game Boy Advance and Nintendo DS. Actually, do one specifically for the Game Boy Color!

[@DJCosmicLatte]

If I'm not mistaken, the GBA does actually have Mode 7 hardware, enabling effects such as 3D perspective illusion, rotation, etc., and plenty of games took full advantage of it.

[@startedtech]

@@DJCosmicLatte it also can render true 3D. There are plenty of full 3D games, check out Punching Weight videos on the GBA. There is some seriously impressive stuff that can not be "faked" using mode 7, Doom-style 3D, Sprite scaling etc. It is true 3D.

[@DJCosmicLatte]

@@startedtech Interesting, I wasn't aware. To be fair, most of the games I've played on GBA used 2D graphics with occasional Mode 7 distortion (ie Pokémon) or isometric views with 3D models rendered out to 2D sprites (ie Spyro the Dragon).

I think what's even more impressive in all of this is the *forwards-conpatibility* -- that the original GameBoy could seamlessly run any GameBoy Color software that didn't need the additional RAM or power, and could at least display a custom error screen for the convex cartridges that did. They really did an excellent job of keeping the GameBoy accessible to its very last breath.

Really great video, you highlights some things about the hardware that I was completely unaware of which gives me a new respect for the little device. To me, the original Game Boy and Game Boy Color stand as probably the finest example of Nintendo's design philosophy of "Lateral thinking with withered technology." It's a sentiment that goes hand in hand on the console side of things in that the most powerful machine on the market during a given generation is never the market leader or most popular.

[@dan_loup]

The GBC trounces the game gear in almost everything but colors per tile. It's quite a step up from the original spinach little box.
