Are there any particular barriers to go from “have most” to “have all”? Unlike the endless task of preserving PC software, it would be nice to say the consoles are “done” from a preservation standpoint.

I just squared a cross fade last week...

Compilers will often remove that completely, because it can be statically determined, which can lead back to the original problem.

Yes, I did the original work, but I can’t do any updates now...

MSAA doesn’t help fonts at all. For a chunky pixel font, magnify it by 3x, so an 8x8 is 24x24, then use bilinear filtering.

Yeah, I understand it wasn't there on the production hardware, my question is why MS didn't ask for it during design, since they would have been aware of the annoyance that big endian would be.

I never saw a PPC NT box, but this article says it ran the cpu in little endian mode, which makes me all the more curious why they didn't make the XBOX 360 that way:

I know it is used with still images, I was thinking about the video recording case (on a tripod), getting different subpixel offsets per frame.

I wonder if you could synchronize vibrating a camera sensor with the shutter to deliver super resolution over multiple frames. A 2x quincunx pattern at opposite ends of a sine motion seems do-able.

It is always surprising how much code breaks when operating on a 3GB file with internal offsets that set bit 32.

I'm no better than most at tune estimates. Someone: "We are budgeting ten weeks" Me: "I can do it in a day" <takes three days>

The system has always supported h265 for sideloaded content, but the browser still doesn’t.

It can go to 5760x2880 30 FPS, but that isn’t worthwhile from an aliasing perspective. It would be great if Samsung also updated, since the exynos chips can already do those res.

Should be the same as a snapdragon S7. The one difference is that we have a firmware update coming out soon that supports 5120x2560 30 fps, which the Samsung snapdragon systems don't.

I generally agree with this for realtime applications -- you want to know about it with an assert or log if your generous mental model of how many things there are going to be is actually in error.
