A couple of months ago we shared a video by JackTech, which explored in some detail how the Game Boy CPU works. It was part one in a 'hardware autopsy' series that aims to unpick and explain how the iconic portable device operates, providing some insight into how humble technology was used in clever ways.
The second part has now gone live, this time looking at memory mapping - for the tech-inclined this looks at how behind the scenes operations helped the portable make the most of its resources, and how different parts called on different memory.
It's an intriguing watch - you can check it out below.

...Magic!
I can't find a comfortable seat right now, added it to my Watch Later list... will be investing in comfortable seat.
Hokey smokes. You have to get bombarded with math just to acknowledge a button press.
Kinda like bureaucracy...
Genuinely fascinating stuff.
The amount of things there are which can be learnt about classic videogame hardware such as the Game Boy astounds me.
...This video is giving me a headache.
Conclusion: carts > discs.
At 5:29 (where it talks about memory used for the display, buttons, etc), it's 128 bytes, not 127, because address $FF00 also counts.
Great videos. But they always leave me hanging. Lol. I guess I got used to binge watching.
cliffhanger nooooooooo

Hey, is that Clyde Radcliffe from Creatures (C64) on your avatar?
As for the video - since I used to program stuff in Z80 (GB) and 68K (Mega Drive) assembler as a hobby in my free time, I found it very enjoyable. Love watching (or reading) stuff like that!
@PlywoodStick Yet you complained about Fates should be able to get all three paths in one and not realizing it being an expensive thing to do.
@Fuz
High five, then! Creatures 2 is one of my all time favourite C64 games!
TLCS-900? The one from the Toshiba microcontroller family? If so, then I remember working with it during one of the classes, way back at the University. Awesome stuff!
@Socar Well... Fates is on a card, not a cart. (Discostew pointed out the distinction between cards and carts in the past.) So it's not that expensive. I think $60 retail would have covered it. But I understand that the risk would be higher on such a deal, so they went with the DLC model instead. (As it turned out, it would have still sold like hot cakes!)
@Shiryu Ma*pffhhhe*gic - drooling :^(
Really interesting video! As was the first part (also, there is a part 1.5 to correct some mistakes).
This seems to become a great youtube series, now I want to see the next episode.
