Important Windows 8.1 hotfixes and Windows Server 2012 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 8.1/Windows Server 2012 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows 8.1 and for Windows Server 2012 R2" section. MUM, MANIFEST, and the associated security catalog (.cat) files, are very important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems.

I updated my ray marcher to use RGB colours internally and random dither back to 16 colours.This should allow me to add things like partially transparent surfaces, or atmospheric fog at some point.
This is a flicker palette expansion demo that uses 59 colors of an available 136 "colors" to animate a randomized, circular rainbow "video wipe" style effect. This is achieved by drawing two different colors on the same pixel in quick succession to dazzle your senses into tricking your brain into thinking it's seeing more colors than Pico-8 can actually draw. It looks okay at 30 fps but really benefits from 60 fps.
Apparently there is historical evidence of arcane "Super CGA" video cards using this method to expand the color palette of old 16-color monitors from a bygone era. Cool stuff. Most of the CGA cards like the CGA board that went into the IBM PC XT back then were only displaying four colors at time so there wouldn't have been much incentive to write a piece of software that actually used this technique.
This GIF image example is 30 fps since capturing a GIF at 60 fps only shows one half of the frames so the effect is lost in the conversion. This 30 fps example is also slow enough to give an idea of how the effect is achieved: each band of colors is actually three bands wide. The code runs at 60 fps which looks 100% better than the example GIF.
I found cart by dw817 called "256 Colors" with Pico-8's "Lucky Draw" feature which looks to be showing at least 136 unique colors (and 120 duplicates) which was where I got the inspiration to try something similar. I had been watching videos about legacy computers and just had to try this out. It's easy to imagine how someone might have been able to get old 16-color CGA monitors to behave in a similar fashion either in software or with special hardware.
Shout out to David Murray "The 8-Bit Guy" whose video "Meet the Super CGA Cards" discusses specialized CGA video cards like the Plantronics Colorplus and the QuadColor II. I think I just figured out how the Quadcolor II supposedly has support for 136-color on 16-color displays. dw817's cart is a literally picture of a similar set of colors using Pico-8s official 16-color palette.
I highly recommend "The 8-Bit Guy" to Pico-8 developers for some insights about what 1970's and 1980's era PC gaming was actually like. Does anyone remember when the swatches in Microsoft Paint in Windows 3.1 were dithered on some systems because the hardware didn't support the colors? Nostalgia ...
I haven't implemented any dithering which seems to open up quite a bit more color options. There might also be a way to flicker in an extra color layer or two for broader color depth but at a considerable cost to frame rates.
There's lots of little variables you can play with in the code to change how this little tech demo behaves. I think of it as a piece of parametric software but I haven't yet brought out the parameters to the GUI so this cart would benefit from that work.
There's no music but this might be a good effect for any demoscene kinds of work I might do with Pico-8's amazing synthesizer capabilities which I barely know how to leverage in code at this point but after discovering luchak's "RP-8" cart I need to dig deeper, awesome stuff.
Feel free to use, optimize or expand this code in any way your see fit for example to accompany music, simulate shock waves or whatever other project you're working on if you just need to slap a flickering rainbow on something. It can easily be modified to use other colors and might look amazing with some fast dithering techniques maybe using special characters or something.
My last jammy thing was qdlst(), the Quick 'n' Dirty Locally Similar Tiler algorithm that I subsequently used to build Greave, the dungeon crawler I released this past weekend. Today, for a change, I decided to try my hand at a worldmap builder in the vein of Civilization.
Being as I was on an airplane and was not about to shell out good money for lousy wifi, all I had to work with was PICO-8 and the text-based manual. Since I couldn't remember any perlin noise procedures off the top of my head, I had to improvise, which is more fun, anyhow. I decided to go the geological route: I'd build a world by pummeling a blank slate with a bunch of meteors. add a little random noise every ten rounds or so, and you've got yourself a planet!
The end result is surprisingly nifty and builds a cool 128x128 world map in a matter of seconds (toggle the real-time viz off by pressing the up button to see the algorithm work at full speed.) Use the left and right arrows to increase/decrease the number of meteor iterations the program goes through.
In order to expand Pico-8's scope of influence and interest, I was wondering if it was possible to compile a Pico-8 cartridge to a new kind of EXE. Not one that requires Windows as it can now but runs perfectly well in DOSBOX ?
The code has a string and number stored to find in memory.There is also a graphic and sfx to locate in memory.I initially made this to look at the lua code and answer a few questions I had like what the endianness of the CPU is (it is little-endian if I worked things out correctly). Perhaps there are other things that can be found about the CPU. Maybe I could add a way to poke values in to test things.I whipped this up and added a few features to make things a bit easier. Do whatever you want with it. If the BBS gave me the option I would have put it as CC0, but I selected CC4 because it was closest. 2b1af7f3a8
