I've looked at Visual 6502 and it's way beyond me. I've even looked at the scans where it shows how they severed the connection to disable 6502 decimal mode on the NES.

There seems to be a bug in the code for handling input, certain combinations of pressing or releasing left and right can cause the paddle to get stuck moving to the left or right, especially when Left and Right are held down simultaneously.

MRAM (magnetic and non-volatile) had some applications in GBA cartridges to replace small amounts of battery-backed SRAM.

Great, now converting a float to int will cause the C compiler to randomly reformat your hard drive...

Focus of controls is the hard part. You end up needing a Per-seat version of focus in an application.

How many Portal test chambers could be solved with Mario 64 jumping alone, and no use of any portal gun?

Maybe count perfect solves in a separate average than solves with mistakes?

When I mentioned "perfectly reversible", I meant the FFT itself. You run the FFT. You run the inverse FFT. Because the FFT was quantized to 0-255, you end up with a lot of stuff that doesn't belong in the image.

That one does not seem to be an undither project, it appears to be a special way to encode chroma information within a monochrome dithered image. NTSC television also encodes chroma within a grayscale signal, but that's different than black and white only.

Speaking of which, are there any good ways to undither images? Things like GIMP FFT are not perfectly reversible.

We know that crooks are selling fake drives where the size is over-reported. Shouldn't something that tries to be sneaky under-report the size instead? Not just in the partition.

A magazine disk was the first time a game containing Sonic the Hedgehog was released. He was thrown into a game as an enemy character in a platformer game (Adventures Of Quik & Silva) without any regard for copyright law. This happened before the actual Genesis/Mega Drive game released.

(and no, that game is not on this site)

When you have a dialog window too big for the screen, you can Alt+Space to open the system menu, then activate the Move menu item, then you can use arrow keys to move the window around, even with the title bar out of bounds.

Not just for obsolete systems, sometimes a full screen application might pick a tiny desktop resolution as well, and not properly restore the resolution, so you could need to deal with a too-big dialog box in that situation as well.
