MII Version Changelog

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's a bit more useful, and looks cooler.

Poor quality gif, It is a LOT smoother at 60fps in the program!

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!

Super Serial Card config dialog

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).

Made an architecture document, see Compiling 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.

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.

DOS 3.3 Disk 'bitstream view' on the left, the green trace shows what's just be read.

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 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
