- GdiSetBatchLimit() fails with 0
- GdiGetBatchLimit() returns 20
Removed GdiFlush from VideoRefreshScreen():
- GdiFlush() only for GDI draw functions (not StretchBlt!) that return a BOOL
- stops tearing
Moved WaitForVerticalBlank() before StretchBlt()
- window is updated after StretchBlt(), not after GdiFlush()
Still get juddery animation.
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
