The Gameboy is the perfect example of using technically outdated technology to make a truly awesome product noone had seen before. The game gear and lynx might have been more advanced, but with battery life being small, no one could really play them for long periods of time.

Indeed. The Game Gear might have basically been a portable Master System, the 6 AA batteries it required (and how fast it munched through them) was definitely a major downside.

The battery life of the game gear was actually good, just not in comparison to a slightly beefed up calculator (dmg). Blue LEDs did not exist at the time of the game gears release, which is why it had to rely on a compact fluorescent tube to provide backlight. This tube is what actually consumed the majority of the battery life. Remember that the nintendo switch has the same battery life as the game gear. Oh how far we have come 💁‍♂️

@@CrossedCoder true about the technology used and all, but I don't think it's fair to compare battery life between products nowadays with rechargeable Li-Ion ones that last for quite a few cycles, vs disposable batteries or the occasional Ni-Cd ones (that sucked) or Ni-MH (which some people say were super common in early 90s meanwhile many people didn't even see them until the early 2000s... very varying experiences regarding those. Also price wasn't what it was in early 2000s). But it indeed is quite terrible how fast a Switch goes through it's battery, and I would even say that the Lynx and Game Gear competed between each other, while the Game Boy was doing it's own thing barely related, and that proved successful instead. The Game Boy went with a cheaper and more feasible alternative, the other two went with the cutting edge. Hard to even think they competed.

it always blows my mind back when hardware was so limited, programmers had to be really creative just to do simple things things we now take for granted. it adds a certain magic to the finished products.

A lot of this is wrong. You can't combine AF into a single 16-bit register (except when saving/restoring to stack). F isn't a general purpose register, it's flags from the previous operation. The hardware and games don't use the header information at all. The Game Boy only checks that the logo is correct (a failed license control system) and the header isn't corrupted. Super GB and GB Color check for some flags to enable their features, but nothing uses the type/size fields. Games were generally coded to assume they had the correct chips (because why wouldn't they?) and would just go ahead and use them without needing any setup or checking. The MBC chips are basically just simple latches for the high address lines of the ROM chip. Nothing prevents a game from trying to access more banks than it really has. It would typically just read back an earlier bank because the higher address lines aren't being used. It's all fairly simple transistor logic, so there's no complex protocols or verification. You just directly control the hardware. How the ROM area and extra RAM are split up is entirely up to the cartridge. While most (all?) licensed games followed the rules outlined in the video, they aren't enforced by anything. You can make a cartridge with different bank sizes, different control methods, ROM in the region usually used for RAM and vice versa. The only restriction is that it needs to have the logo and startup code mapped to 0100 at power on. (Some unofficial cartridges even did some timing/mapping tricks to swap out the logo for a different one after it was verified, so they could display their own!) Technically there's no limit to how many banks you could add to such a custom cartridge, either.

I don't like saying "when the system knows [...] thanks to the header information" that I just feel is completely inaccurate. The header information is purely descriptive, and its only useful parts used by the boot ROM is just the Nintendo logo portion and Header checksum. The only real use of all of it is as metadata for emulation (or perhaps Super Game Boy). A game's code only rightfully assumes that the hardware is already present and does not base itself on the header information to know. The system itself is completely blind to this and doesn't do anything in particular, the game will do the job needed itself.

I was about to make the same comment. A real game boy DOES NOT USE this header information, it is simply documentation of what the cartridge circuitry itself contains. This is meant to solve the problem NES ROMs had, which is that a ROM dump alone tells you nothing about what hardware the cart contains and is therefore not enough information to emulate the game, for example.

This video has some rather rough misinformation. At about 5 minutes in the presenter demonstrates they haven't understood that the cartridge is literally where the game is running from; there's no load step, nor memory to hold bank 0. Next comes the direct contradiction of "the programmer didn't need to write their own controller code for the bank switching" quickly followed by "they were still responsible ... to let the MBC chip know". It's all magic! The best part of the video is the cut in to note that nothing here is unique or new to the Game Boy, as the rest of the script misleadingly suggests.

Super Gameboy wouldn't care since it has the same physical cart as the Gameboy. Otherwise yeah I was going to point out a lot of the same stuff you did. In addition AFAIK the split of 16kb between bank 0 and bank X was probably up to the cart. The Gameboy is just asking the cart "what is at address 0x3000?" and the cart has complete freedom in how it answers. So the bank switching didn't need to be supported by the Gameboy at all, it was all on the cart. But it was standardized by the set of standard MBC chips commonly used, hence the common behavior of a 16kb bank 0. AFAIK there was nothing stopping someone from making bank 0 8kb or making a bank X and a bank Y that could be switched independently. You could even remove the a dedicated bank 0, but the problem is the code you are running from when switching banks should not change since, well, you need to be able to read the code you want to keep running. Most reliable way to do this is set aside some address space which is guaranteed to not change when bank switching and always do bank switching from there, which is exactly what bank 0 does. The innovative thing about the Gameboy it would seem is how far Nintendo took advantage of being able to cram custom hardware into each cart. I am sure they wished they had added some of those capabilities to the system itself, as it would have been cheaper overall to not have to make this hardware for each cart but just each system, but of course lessons learned would go on to influence future Gameboy hardware design. It's also worth noting carts were well established by the GB era. Atari and their competitors back in the day used them. NES used them of course, and NES carts used custom hardware as well (IIRC SMB3 2D scrolling was only possible thanks to this). Some arcade cabinets allowed you to swap out boards to have different games run (not sure where in the timeline this falls if it predates home consoles or not, but it is definitely the most primitive way to do it).

MVG, I love you, but I'm annoyed that there a whole bunch of small inaccuracies in the video. If you're interested, the next time you're going to do a video about Gameboys, I can offer to proofread the script. (I'm the person who runs the GB dev wiki, btw.)

Great video - sure there are some small inaccuracies but it does a good job of explaining the basics. I was a Gameboy Color programmer back in the day, we used MBC 5 for a 4MB cartridge and external save-ram. It's tricky to develop with bank switching in mind, because the moment you switch banks, that entire bit of ROM is now filled with entirely different data, so if you want to access some of the same things (like animated status bar graphic tiles), you either have to keep those in the extremely limited Bank 0, or load them into the even more limited RAM, or duplicate them in whatever banks you are switching to while the status bar is on the screen. When you start developing a game, you'll organize it - "Bank 64 for minigames A and B, Bank 65 for combat effects, Bank 66 for the title screen and menu", etc. But by the end, you are cramming bits wherever they can fit, it gets ugly.

@eDoc2020

3 жыл бұрын

Doesn't the GBC only display from VRAM? Couldn't you just switch to the bank with the needed tiles only once per frame during the update routine? = But yeah, it's just plain so much easier to develop software with a linear memory map. Devs for 16-bit x86 will have similar difficulties with segment switching as GBC (and other) devs have with bank switching.

@@eDoc2020 I was trying to quickly come up with a simple example of the need for shared data :) Been like 16 or 17 years since I actually developed on GBC, so my memory is hazy of exactly what the problems were we ran into, but we pushed the system HARD, far beyond what it was designed for (ie, hundreds of colors per frame), so ran into a lot of tricky bits because of the need for bank switching.

I received a Gameboy for my 10th birthday, and it was one of the best gifts I ever received. So many happy hours with that console. Strange to think that was 28 years ago. Utilising the cartridges to get more space is bloody genius!

In the very late 90s, I was briefly fascinated by assembly programming on TI graphing calculators. They were Z80-based systems (the one I had, anyway) and were in some ways comparable to Gameboys. It's great to get an idea of just how different the actual Nintendo Gameboy was, though.

The MB Microvision had a much more interesting cartridge system, the CPU was stored in the cartridge plate! Would love to see a video on that The first 256 bytes are actually used for the BIOS of the gameboy. The BIOS is swapped out when it finishes processing and the first 256 bytes are no longer reserved once the game itself is actually running With the proper mapper you can make both banks swappable, although it does make programming more complicated. Also, with the correct technique you can hot swap cartridges by copying a short look into RAM so that the processor is no longer looking at the cartridge while you swap it, and then you can jump back into the reset vector yourself to start the new game. It was never done in practice but it is possible!

The reciprocating action of pushing the plastic lid in and out created a high enough charge to become an ESD sensitive device destroyer. Not a well thought out cartridge design.

I may be 21, but I grew up playing Mario Deluxe, and Rampage on an old Atomic Purple Gameboy Color that my dad gave me when I was 5-6, and I loved it. I also loved tech in general from what I recall I'd take things apart, and put them back together often back then, and my parents tried to encourage it, which I'm thankful they did. We didn't have much else, cause we wasn't well off, or anything. However I loved the things I did have, and enjoyed them thoroughly. I don't have that old Gameboy Anymore due to so many moves, it must have gotten left behind, or lost along the way. However I recently reacquired a Gameboy Color Atomic Purple online, and have been playing Pokemon Yellow, it's so much fun I even forget I can play modern games now on my Switch, Gaming PC, or PS4. I don't know if it's just nostalgia, but it's true what they say, nothing beats playing on the original Hardware. I also have a DMG, and I love the bulk it has, it just fits in my hands so well, even if the LCD is so much better on the Color.

I remember these back in 2000 in elementary school my friend had a yellow game boy and played Pokémon red green and blue GTA and couple other games. I remember it being really cool for being 10 years old at that time

Bank switching was common in the 8-bit days, most of the old home computers were doing some form of that, at least to switch between their own ROMs and parallel RAM sections. Even the Atari 2600 from 1979 did it. However the Gameboy was solid in wrapping up the best of the whole era.

Oh boy countless hours spent with this beautiful handheld console.. Worth every single penny, the one i have still works flawlessly to this very day.

I don’t understand much of this technical talk but they’re still good videos to watch.

I remember a long time back there was a very special cart made ...it had a cable out the back that would connect to Aprilia scooters (Direct injection models) and you could derestrict them. First time I seen it I was amazed , it was cheap enough and all you needed was a regular gameboy to use it.

I'd say taxi 2's intro - although much shorter - is even more impressive as it's a real movie scene instead of an animation and all on GBC.
