+# MII Version Changelog
+## 1.9
+#### Video
+ * Video driver now only draw when the apple II video *really* changes. It keeps track of touched lines across the screen, and only updates when needed. This saves a considerable amount of CPU time.
+ * Redid the monochrome video rendering, low-res, double low-res and dhires
+   now have luminance based on the color, and not just a fixed value. This
+    makes the monochrome rendering a lot more accurate (and attractive).
+
+ * Added 2 other RGB color palettes, an alternate NTSC and the Mega2 (apple IIgs) one.
+
+| NTSC Palette                         | Mega2 Palette                        |
+|--------------------------------------|--------------------------------------|
+| ![NTSC](docs/screen/v19ntsc.png)     | ![Mega2](docs/screen/v19mega2.png)   |
+|--------------------------------------|--------------------------------------|
+ * Added AVX/SSE/generic vectorial versions of some code paths, for speed.
+ * Added some more 'artifacts' color frindges to the HIRES rendering as well.
+
+<p align="center">
+   <img src="docs/screen/v19artifacts.png" alt="Artifacts">
+</p>
+
+#### Other bits
+ * Fixed a bug in the floppy stepper motor code that was preventing some floppies (demos, but also some prodos disks) from booting.
+ * Reworked the SmartPort code a bit, should be more compatible with some prodos programs. Also fixed a crash in block reading code.
+* Joystick can now be plugged after starting the emulator, it will be detected.
+* Changed the way the 65c02 core emulator is interfaced to the rest of the emulation. It was made to be 'pretty' but was also quite suboptimal, so I made it a bit less pretty, but it is now easily twice as fast as before.
+* While before the emulator was using perhaps 25% of a core on my current machine, now it uses about 9% CPU for the same task.
+* The 'floppy' and 'hard drive' file selector dialog now has a small popup menu with the last few directory used, so you can quickly switch between them.
+* Added support for 'pasting' text in the emulator. Paste your pet BASIC programs, it works now. (Control-SHIFT-V -- not in a menu yet).
+* There is a non-functional Mockingboard driver in the code, it's not hooked up to the UI, it still needs work (mostly make the audio output work).
+* UI library got a massive overhaul, since it was released separately it had to get a serious cleanup. Some files are duplicated unfortunately, but that is needed to be able to use it as a standalone library.
+
+## 1.8
+ * Changed the floppy disk view. *It now rotates*, and the heat map is now a
+   'trail' of the head, showing where it's been. It looks awesome!
+
+<div align="center">
+  <img src="docs/screen/v18new_display.gif" alt="New Floppy display">
+</div>
+<center><i>Poor quality gif, It is a LOT smoother at 60fps in the program!</i>
+</center>
+
+ * Added support for a *Ramworks III card*, with 1MB of RAM. It could have more,
+   but I thought and extra whole friggin MEGABYTE was enough for anyone.
+ * Added support for flashing text in text mode. I know, it was a bit of a
+   glaring omission, but it's there now.
+ * Internal changes to the UI, I've split the whole codebase into a few more files,
+   split the 'XORG/GLX' code from the 'Pure GL' code from the 'MII UI' code, so it should be a lot easier to port to other platforms.
+ * Redid the *DHRES rendering*, it's now a lot more accurate, has the correct
+   artifacts. It's not as optimized as the previous version, but it looks better.
+ * Now remap the *joystick* coodinates to a 'square' -- my current 8bitdo joystick
+    has a circular deadzone, and it was a bit annoying to use. I might make that
+    a setting, but for now, it's hardwired.
+ * *Emulator now passes a2audit*. There is only one kludge to do it, regarding the
+ 'phantom read' of the indirect addressing.
+ * *Working Super Serial Card Driver*, it can bridge to a Linux /dev device for the moment, or to
+   a 'fake' loopback device. IN#x and PR#x works, and I can bootstrap using
+   ADTPro. It's all in there so I can run Mastodon!

+### libmui
+ * Standard file picker now shows *floppy icons*.
+ * Added a *Color Apple Menu*, in pure Macintosh II style.
+<div align="center">
+  <img src="docs/screen/v18colorapple.png" alt="Color Apple">
+</div>
+
+ * Fixed a few minor memory leaks.
+ * Tons more stuff in libmui, inc new font styles (bold, underline, condensed). There is also a text edit control now (still prototype).
+
+### Internals
+ * Made an architecture document, see [Compiling](docs/Compiling.md) for a top-down view.
+ * Ported the support for VCD (Value Change Dump) from simavr, so I can now
+   record and playback the whole simulation of the floppy driver. No real use for the user.
+ * Split the video rendering into bits with a 'main' line rendering function pointer that is set only when video mode changes. This is a bit faster, and that gets rid of the Giant Function.
+
+## 1.7
+ * New animated about box, because, everyone loves a good about box.
+ * Added support for Write Protect of floppy disks; disk can be write protected manually, or if the file lacks write permissions, OR if the file format (NIB, DSK) doesn't support writes.
+ * New fancypants 'bit view' of the floppy are they are read/written, with a
+   heat map to show where the head was last. Drive 1 appears left of the screen,
+   drive 2 on the right. It fades out after the drive motor stops.

+<center><i>DOS 3.3 Disk 'bitstream view' on the left, the green trace shows what's just be read.</i></center>
+
+## 1.6
+ * Another big update, yanked the old DiskII driver, and replaced it with a
+   homebrew one, low level, with native support for WOZ (1 & 2) files (*read AND write!*) as well as NIB and DSK (read only).
+ * This is big news, and MII can now boot all kind of copy protected disks, in
+   fact I tried a few hundreds, and they all worked so far!
+ * There is currently no way to create a new disk, but you can use a tool like
+   [CiderPress](https://a2ciderpress.com/) to create them, and then use them in MII. Or just copy your DOS 3.3.woz file and reformat it!
+ * There were a few other minor changes, mostly added some timing measurement
+   tooling, and a couple of (necessary for disk to work) tweaks to the emulator
+   itself as it was not counting cycles correctly for a couple of instructions.
+ * The UI now has support for pure power-of-two textures, for really old OpenGL
+   implementations, it is turned off by default, but could work with some
+   old hardware. Also updated *libmui* to make it less linux-centric.
+ * Fixed some more color issues, mostly DHIRES.
+ * Added 'typeahead' for when you select files in the dialog, like on old Macs
+## 1.5
+ * BIG update, loads of changes, fixes, improvements.
+ * New super UI, using home-made libmui, channeling both GS/OS and MacOS 7.x!
+ * New emulation fixes, way more accurate. Video redone, audio redone.
+ * New front-end program using XLib and OpenGL 'low level'.
+ * New Icon.
+## 1.0
+ * Fixed a few graphics rendering bugs/color swapped
+ * Fixed a few Makefile issues involving pathnamed with 'spaces' in them.
+ * More tweaks to the emulation, added a few cycles here and there.
+ ## 0.9
+ * Added a 'debugger' shell, accessible via telnet.
+ * Added a mini-assembler, used to compile the drivers and the CPU unit tests.
+ * Added a 'Titan Accelerator IIe' simulation, to turn on/off fast mode.
+## 0.5
+ * Initial release

+
+*Note2:* UI Library has moved to [libmui](https://github.com/buserror/libmui)

 I know there are many out there, but none of them were ticking my fancy, so I decide to write my own. To start with it was "How hard can it be really?" then it snowballed as more and more things were fixed & added. It's been shelved for a while because well, it lacked documentation, headers, licence and stuff, so I spent some time cleaning it up for release.
 
 One primary reason for this project was that linapple (or -pie) codebase is really horrible. It dates back from 2000's or before, with loads of Windows crud leftover, some SDL crud added, the audio just doesn't really work, and overall if you want to hack around the codebase, it's pretty dreadful.

 ## What needs doing?
 * I'm sure there are bugs. I haven't tested it on a lot of hardware, and apart from quite a few games and a few known productivity app, it had had very little extensive testing. So testing!
 * In the code there are a few bits which needs fixing
-   * The mouse card is not working properly. It works for some (most importantly A2 Desktop), but it's not working properly. I suspect the VBL Interrupt handling.
-   * In mii.c, the *mii_page_table_update()* does work, but it sub-optimal, it was handy to debug the countless combination of soft-switches, but it is not the ideal way to handle that problem; it needs a proper switch-case statement.

-   * Plenty of the most complicated piece of code (video, memory mapping) load a dozen of soft-switches, it probably should use a separately maintained bit field that is maintained by the on/off switches, and would make it a lot easier to test for bit combinations.
-   * The static array of memory 'banks' works, but it prevents me easily making a memory extension card. It should be refactored at some point.

+# MUI Version Changelog
+
+## 1.2
+* More tweaks to the menus. Popup menus can be justified left/right/center. Removed quite a few fudge factors.
+* Added a notion of a control (per window) having the 'focus'. Currently listboxes and text edit boxes can have the focus.
+
+## 1.1 -- since the release of the original verison
+* Added support for horizontal scrollbars.
+* Added a faster (vectorized) version of an obvious 'cg' function.
+* Fixed a problem with mui_timers. Also typed it now.
+* Added a bunch of extra comments to mui.h
+* Added a *fully justified* text style for text boxes.
+
+## 1.0 -- original version

 # Why?
 Well I wanted a UI library for MII -- something without tons of dependencies, and I didn't want the typical 'game like' style with "Arrow Keys + Return + Escape" sort of menus.
 
 I started with Nuklear immediate mode UI, but it both look super ugly, AND is very limited as soon as you want to do something 'custom', and I didn't see myself hacking into that codebase. One thing I particularly dislike is the 'layout' engine that decide to put stuff where it wants, and it's *never* in the 'right' place, like a hard case of 'computer say so' -- typicaly result into

 The other things I don't like with the trendy IM UIs is that they promise you that you don't have to keep a separate state around blah blah, however they forget to mention that there IS a state kept for you, based on hash values, and if you are unlucky enough to have a hash clash, you are screwed. I've seen that happen in real life, and it's not pretty to debug.
 
+I miss the days were UIs were /crafted/ not just decided for you bad a bad 'layouting' engine with huge rectangular flat buttons and no sense whatsoever of 'design' or usability.

-The cool thing about ui_playground is that it loads ui_test.so as a *plugin* and auto-reload it if it detects a change. So you can hack around ui_test.c, and it will reload it and run it again! You can code a new dialog insanely fast with that, pretty must as fast as you would with a resource editor.

-A good trick is to use 'make watch' on the *libmui* directory in a terminal tab, and it will rebuild the library and the playground automatically when you change something, that with the 'auto save' of your editor, and you will have a constantly building/running playground as you hack around.

+ * This file defines four types of data structures: singly-linked lists,
+ * singly-linked tail queues, lists and tail queues.
+ *
+ * A singly-linked list is headed by a single forward pointer. The elements
+ * are singly linked for minimum space and pointer manipulation overhead at
+ * the expense of O(n) removal for arbitrary elements. New elements can be
+ * added to the list after an existing element or at the head of the list.
+ * Elements being removed from the head of the list should use the explicit
+ * macro for this purpose for optimum efficiency. A singly-linked list may
+ * only be traversed in the forward direction.  Singly-linked lists are ideal
+ * for applications with large datasets and few or no removals or for
+ * implementing a LIFO queue.
+ *
+ * A singly-linked tail queue is headed by a pair of pointers, one to the
+ * head of the list and the other to the tail of the list. The elements are
+ * singly linked for minimum space and pointer manipulation overhead at the
+ * expense of O(n) removal for arbitrary elements. New elements can be added
+ * to the list after an existing element, at the head of the list, or at the
+ * end of the list. Elements being removed from the head of the tail queue
+ * should use the explicit macro for this purpose for optimum efficiency.
+ * A singly-linked tail queue may only be traversed in the forward direction.
+ * Singly-linked tail queues are ideal for applications with large datasets
+ * and few or no removals or for implementing a FIFO queue.
+ *
+ * A list is headed by a single forward pointer (or an array of forward
+ * pointers for a hash table header). The elements are doubly linked
+ * so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before
+ * or after an existing element or at the head of the list. A list
+ * may be traversed in either direction.
+ *
+ * A tail queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or
+ * after an existing element, at the head of the list, or at the end of
+ * the list. A tail queue may be traversed in either direction.
+ *
+ * For details on the use of these macros, see the queue(3) manual page.
+ *
+ * Below is a summary of implemented functions where:
+ *  +  means the macro is available
+ *  -  means the macro is not available
+ *  s  means the macro is available but is slow (runs in O(n) time)

+	calls into the Cx00-CxFF area.
+
+	Once running, the thread will monitor the 'tty' file descriptor for each

+
+	The SSC driver itself just monitors the FIFO state and update the status
