Quote:Jan 29th, 2012 - DS2x86 version 0.32 released!

This version only has a few minor improvements. I have only had a couple of days to work on DS2x86 during the previous two week period. As it will probably take me another two weeks to get the graphics blitting improved, I decided to release a new version today, even though it has not had much work done compared to the previous version. This is what is new:

Mouse emulation has been implemented, it should now work similarly to DSx86.
Screen mode "Scale" in high-resolution modes scales also in Y-direction.

The lack of progress is mostly due to an extended electrical blackout that occurred on last Monday, and which (indirectly) caused two of my three computers to die. My laptop (which is almost 9 years old and still had the original battery) ran it's battery empty during the blackout, and it looks like this finally caused the battery to fail completely. The machine does not run without a battery, so I had to order a new battery for it. Somewhat surprisingly some online stores still sell (and have in stock) batteries suitable for a laptop that old!

The bigger problem was that the motherboard in my HTPC also died. It was less than two years old, so it should have lasted longer, but of course it only had a one-year warranty. So, I had to spend all my free time last week with first familiarizing myself with the current status of suitable hardware for a HTPC machine, then online shopping for parts, modifying my silent cooling system to fit a new socket type, and then finally building and configuring the new machine. That left no time for me to work on DS2x86, as I only got the new machine up and running yesterday evening.

I hope to finally get back on track with working on DS2x86 during the next week. I first want to improve the screen blitting speed and quality in the higher-resolution modes, and then I really need to re-implement the SoundBlaster digital audio support. Sorry that it will take so long for me to get around to these, but sometimes unexpected complications arise.

Source Changes
--------------
Rewrote tilemap.c as a C++ class. For now kept the global functions
and just inline mapped them to the class. Will do a pass soon to
actually update drivers to use the C++ methods directly. Also, the
tilemap callbacks are now delegates which should make for cleaner
integrating into modern devices and drivers going forward.
[Aaron Giles]

Add libjpeg; converted Sliver to decompress pictures on the fly
[David Haywood, R. Belmont]

Remove support for 4bpp packed graphics. These only manifested for
drivers that used GFX_RAW support for 4bpp systems, and yet we had a
bunch of extra code to support it. Updated these drivers to do without
it and removed all the extra code for supporting it. [Aaron Giles]

tagmap is just a C++ template now. Added iterators to it as well.
Updated a few outlying uses. [Aaron Giles]

bunch of kludges [Angelo Salese]

Added Intersil IM6402 UART emulation. [Curt Coder]

Added documentation (pinout/dips/chip ID) for popobear based on PCB
picture and manual. [Tafoid]

i386: fixed a bug with JCXZ opcode [Carl]

Changes for GCC 4.7 compatibility [Belegdol]

Added FLAC (lossless audio) codec support plus experimental hooks in
samples and chdman. Bumped up CHD-CD hunk size to get better
compression ratios on both zlib and flac. [David Haywood, R. Belmont]

i386: Made stack limit checks better handle the difference between 16
and 32-bit stacks in IRET and RETF. [Barry Rodewald]

i386: Stopped IOPL from being changed by IRET when CPL is zero. [Barry
Rodewald]

addresses/data scrambling for different EPROM types on 16-bit mode.
[Roberto Fresca]

Move devices into a proper hierarchy and handle naming and paths
consistently for devices, I/O ports, memory regions, memory banks, and
memory shares. [Aaron Giles]

Fixed pcap network device search [Carl]

Converted Lemmings, Wizard Fire, Desert Assault, Rohga and Schmeiser

of the two unknown Turbo Out Run sets. [Brian Troha]

oki6295: force creation of banks so loading a state from after the
game has set a bank before the game sets the bank doesn't die
[R. Belmont]

SDL: don't show misleading message for .BDF UI fonts
[R. Belmont, The Flying Ape]

Quote: 2012/01/29 2.64 released
- At setting of "Option" button in the start window, "MiddleLight" button
was added. If your PC power isn't enough, please use this.
- At "TV Mode" and "Horizonal Scanlined" mode (Setting->Screen menu), the
image quality setting of default was changed. The density of scanlines was
changed to 70% from 30%.
- At 640x480FullScreen, Horizonal Scanlined (& TV Mode) and Full-Stretched
Mode, the image quality was improved. * At this mode, a stretch of screen
isn't performed. The FullScreen is drawn with drawing of overscan area.
- The speed and timing were brought close to the movement of a real machine.
In "Circuslide", The problem that BGM occasionally fell into disorder was
solved.
- The processing of switching to full-screen has been improved. (
correspondence to older PC environment)
- Additionally, a detailed part has been improved and corrected.

Quote:Beta 14:

- Input panel qualifier key/button support. I think this was requested many many years ago.
(I didn't originally plan to do this now but someone reminded me few days ago..)
* - Any key or button can be configured as a qualifier (like a shift or control key that modifies behavior of other keys)
* - Any Input Target can be configured to require qualifiers. Input Target only triggers if it's Input Source and all configured qualifiers are active at the same time.
* - If multiple slots are configured, only slot(s) that have matching qualifier will be triggered, for example if slot 1 has qualifier and slot 2 has none: Only slot 2 triggers if Input Source matches without qualifier active and only slot 1 if Input Source matches with active qualifier.
* - Same qualifer code (1-8) can be configured to more than one key/button.
* - Qualifier(s) set to any other types than keys or buttons is currently undefined.
* - End ("*" in GUI), Shift, Alt and Control keys are mapped to built-in qualifiers.
* - Most previously hardwired key mappings (END+F1 etc..) are now implemented using Input qualifier system
* -- Exceptions: F12 so that there is no way for users to accidentally disable GUI access. END+<number> and END+<numpad number> disk swapper and statefile shortcuts, I didn't want to add 30+ new mostly pointless input targets.. Disabled if END-key's qualifier flag is removed.
* - Qualifiers and custom events: slots 1 to 4 and 5 to 8 can have different qualifiers.

- Doubled number of input target slots (4 to 8)
- "Copy from"-button corrupted memory.
- Added keyboard default options to "Copy from"-button. Can select either Amiga or PC default mapping.
- TODO: restore only single input target to default.

- Less than 35Hz vsync display refresh rate: show only every other frame.
- Workaround for strange Windows feature or a bug. First call raw input RegisterRawInputDevices() to unregister HID devices and then immediately call to register them again: Windows randomly stops reporting HID events.
- Windows to Amiga clipboard sharing wrong string size if string contained cr/lf line endings.
- Low latency VSync screen mode switch fixes and updates.
- Native code execution (winlauch.alib etc..) is not anymore allowed by default. Option in misc panel.
