Shameless self-promotion: if you enjoyed Travis' ROM dumping, you might find my piece about sniffing the Game Boy's LCD data bus to take screenshots interesting as well.

> Editing text with various multi-finger gestures
What multi-finger text editing gestures am I missing out on?
Undo and redo:
Undo the last edit: Swipe left with three fingers, then tap Undo at the top of the screen.
Redo the last edit: Swipe right with three fingers, then tap Redo at the top of the screen.

My least favourite “feature” of iOS now is shake-to-undo. I’ve never triggered it intentionally. It’s too weird of a thing to remember when I actually want to do it. It would also feel ridiculous even if I remembered it. The only times I trigger it, it’s by accident, and then I need to cancel it.
You should turn it off then. :) Search for shake in the Settings app.

The Back Tap feature is my favorite "hidden" action on the iPhone. You can double (or triple) tap the back of the phone to trigger whatever action you want. For example, toggle the flashlight or lock rotation. Show Spotlight or run a Shortcut.

I think Apple does a decent job telling people about iOS features across the User Guide, Tips.app, and the Apple Support YouTube channel.
The "undiscoverable" features in the article are all there.
Delete the last digit: If you make a mistake when you enter a number, swipe left or right on the display at the top.

Could you cite a source regarding the claim that "it works well to prevent theft"?
Not disputing your claim, just finding it difficult to find evidence either way.

Delightful! Is it 6502?
Edit: It appears to be Z80. Have you done any NES ASM?
Yes, I've dabbled around with the NES as well. But the Game Boy is close to my heart as I had one as a kid. So most of my projects [3] revolve around that old gray brick.

It's actually Z80-ish with some features missing and some new ones included. It's a Sharp LR35902 SoC with an SM83 core (not sure if it has been used in non-GB SoCs).
I can recommend The Ultimate Gameboy Talk for details on it (and much more).

EDIT: I had the SoC and the core names the wrong way around. Thanks svendahlstrand.
I believe the LR35902 SoC is exclusive for the Game Boy, but the actual CPU core, SM83, is probably used elsewhere. Sharp's datasheets [2] mention home appliances as intended application.

The official Game Boy Programming Manual [0] leaked and is available at the Internet Archive. It's a great resource.
If you're just getting started with assembly and want to look at a short program, my maze generator [1] is available on GitHub with annotated source code.
Petmoj is Swedish slang for a rotary dial.
