This change does two things:
1. Updates the registry APIs to reduce the likelihood of uninitialized
variables.
The code wasn't always checking the return value of registry load operations.
In some cases, this led to uninitialized memory being used, and crashes could
result. For example, LoadConfiguration in Applewin.cpp was using an
uninitialized value for the computer type if no registry variable for the
"Apple 2 type" was set.
New registry reading methods and macros have also been introduced, allowing
default value fallbacks for the cases where a registry variable is not found.
This makes registry access simpler and safer when a default value is known in
advance.
The registry code's style has also been updated to conform with the rest of
the code base (tabs instead of spaces, naming conventions, etc.)
2. Introduces string safety improvements.
A number of code paths have been modified to use safe-string functions instead
of their unsafe counterparts (e.g., strcpy, sprintf). In the process, some
strings were converted from "char" to "TCHAR". This was done mostly for
consistency with the rest of the code-base.
Supports:
- all "woz test images" v1.3 (WOZ1, WOZ2) are working, except 3.5"
- additionally: Frogger (spiradisc), Choplifter (not Enhanced //e!), Lode Runner, Marble Madness, Skyfox.
- woz images can be .gz or .zip compressed (ie. same as other supported images)
- save-state
Limitations:
- read-only, so WOZ images are forced to be write-protected
. as a result, games that need r/w images won't work (Stickybear Town Builder, Wizardry)
- 5.25" only (not 3.5")
- Added Configuration GUI to include checkbox for "50Hz"
- Implicitly use PAL or NTSC base 6502 clocks depending on video refresh rate
- Added new -50hz and -60hz command line switches
- Updated save-state for video refresh rate
1.28.8.0: Updated version & history.txt
Updates for DHGR MIX (#633):
. Support new switch -rgb-card-invert-bit7 to invert bit7 for Dragon Wars.
- Reverted DHGR MIX mode and AN2 off to invert bit7
. Support DHGR MIX mode and AN2 off to invert bit7 (undocumented)
. Improve the video-mode precondition to check for 80COL access occurring before $C05F
. Relax the video-mode precondition to just checking VF_MIXED
. In DHGR B&W mode, then HGR screen is also B&W
. For '50% scan lines', don't blend in NTSC B&W mode (as this was inconsistent with the RGB colour rendering), and DHGR MIX mode would look odd!
For the RGB hires look-up table:
- extended to include the previous video byte's high bit
- so it's now: {previous high bit + prev 2 video bits + next 2 video bits} & current byte
For all the RGB look-up tables:
- reduced from 512 to 256 lines (only 256 were being used, so it was just wasting space)
Refactored CopyMixedSource():
- fixed the Rainbow demo (#627)
- sped up in Debug config
Bumped version to 1.28.3.1.
Support the old AppleWin 1.25 vertical blending for hires:
- extended Config dialog to include 'Vertical Blend' checkbox
- Persist 'Video Styles' to Registry
- new cmd line options to select this style & also select 'RGB (Color Monitor)'
- code refactor to support enum VideoStyle_e (and replaced g_uHalfScanLines with a bit in g_eVideoStyles)
Bumped version to 1.28.2.0.
Supported modes selected via toggling AN3 and clocking in 80COL:
- 140 color mode (Apple calls this mode 2, Video7 calls this mode 0).
- mixed mode (Apple calls this mode 3, Video7 calls this mode 2).
- 560 mono mode (Apple calls this mode 1, Video7 calls this mode 3).
Save-state is also persists the extra state.
And there's a few corrections to APPLE2E.SYM for the 80STORE and 80COL I/O addresses.
Renamed this video mode to: "Color (RGB Monitor)"
Also renamed "Color (Monitor)" to "Color (NTSC Monitor)".
As for the colours: I've changed them from the original 1.25 colours. Instead I runtime-generate the colours from the NTSC code. See NTSC.cpp's GenerateBaseColors(). This shifts the same 4-bit pattern in, combining with NTSC color phase, until the colour stabilises. Then I average the next 4 RGB values to get the final colour. The reason for this is that we now have consistent colours between NTSC and this simplified rendering mode.
NB. The 2 greys (in GR,DGR,DHGR) are now the same RGB value.
Added new cmd-line switch: -videorom <file> to replace the video ROM for the Enhanced //e.
- Support video ROM sizes of 4K, 8K and 16K (top 8K only).
- NB. The rocker switch is set to European video ROM.
F10 (for //e or Enhanced //e models) emulates the PAL //e's rocker switch (under the keyboard) to toggle between European or US video ROM.
Other:
- Fixed debugger's view of the AltCharSet soft-switch (it was showing the opposite state).
* Refactor Language Card:
. MemSetPaging() now not used for $C080-C08F accesses.
- Instead LC registers its own I/O handler like all other slot 1-7 cards.
. Saturn uses base LC's 16K for bank0
* Move all 'modechanging = 0' to UpdatePaging()
Added support for #590:
* Changed Apple II original to default to no LC
* Added new cmd-line switch: -s0 <languagecard|lc>
* Changed so when LC is in slot-0, it now use Apple II+'s F8 (auto-start) ROM
Support for #408:
* added slot-0 LC and Saturn 128K for Apple II and II+
* added save-state support
- for slot-0 LC/Saturn, save the LC state in the slot-0 card, not the //e MMU; and switch to a new Apple2 unit ver2
* added g_Slot0, g_SlotAux
* added new LanguageCard.cpp/h to project and moved Saturn code into these new files.
* updated VS2013,2015,2017 projects
Support partial reads for sequential accesses of 6 or less cycles.
- And 31 or less cycles when in "Disk Access Speed" = "Authentic Speed"
Save-state support for partial read cycle (Disk][ unit v3)
Added boot-time logging for Phasor1.dsk (ProDOS 1.1.1)
. For the 14M video modes (DHGR,DGR,80COL), start rendering 1x 14M pixel early to account for these video modes being shifted right by 1 pixel
. Revert the display width back to 560 by disabling EXTEND_14M_VIDEO_BY_1_PIXEL
. reverted default so that ALT+TAB is not hooked (#556)
. reverted default so that ALT GR's fake LCONTROL is not hooked (#558)
. added new switches: -hook-alt-tab and -hook-altgr-control to support hooking these key combo's (#556)
. When Alt Gr is pressed, then manually post WM_CHAR message on receiving a WM_KEYDOWN (manually translate and account for shift/control/caps-lock)
. Hook filter: suppress Alt Gr's (ie. RMENU's) fake LCONTROL messages
Also:
. Hook filter: allow Ctrl+Shift+Esc (for Task Manager)
. Keyboard: refactor only use accessor functions to get the Alt/Control/Shift state
. Created a dedicated thread with message loop (#570)
HookFilter dll: Only call GetKeyState() if keycode is ESC (instead of every time)
DebuggerCursorUpdate(): reduce sleep from 10ms to 1ms
. When in MODE_LOGO, don't pass WM_CHAR to Apple II keyboard (now consistent with WM_KEYDOWN)
. Small refactor for Apple II keyboard's WM_KEYDOWN handler
Move code for log init & done to Log.cpp
Changed HGR rendering, such that that last video byte (at hpos=64) clears g_nLastColumnPixelNTSC so that the end-of-line off-screen pixel is zero (see #555).
. Fix for GetKeyState() not detecting the special keys as being up (so AKD was erroneously reporting the key still down).
. eg. Whilst pressing TAB, press LEFT ALT, then release TAB.
. Also suppress ALT+SPACE
. PostMessage to AppleWin message-pump for WM_KEYDOWN, WM_KEYUP for these special key combos
. Add special any-key-down (AKD) handling for these special key combos
. Start video rendering from screen position -1 (ie. 1 DHGR pixel offscreen)
. Allows 559th DHGR vertical column to be visible
. But now an HGR HCOLOR=2 vertical line at column 0 is only 1 DHGR pixel wide
Also:
. Fix TEXT80 to be aligned with DHGR
. Fix FLASH in TEXT80 (inverse aux bits needed to be masked with 0x7f)
