Split MouseInterface to isolate DirectInput code.
Avoid overflow in platforms where RAND_MAX is a big integer constant.
Fix include files for gcc (where enums cannot be forward declared).
Switched Mockingboard/6522 Timer interrupts & Mousecard's VBlank interrupt to use synchronous events.
This is a linked-list of ordered timer-based event, where only the head of the list needs updating after every opcode.
Video mode: "Color (RGB Card/Monitor)"
. RGB HGR rendering (no half-dot-shift, no vertical blend)
. RGB DHGR rendering
- Color 140-mode is a real 140x192 mode with no color fringe (Video7 patent, shows that way on real hardware)
- Mixed mode: correct transition for Color 140-mode <-> B&W (validated on a real IIc adapter.)
. Complete Féline support (eg. 2 distinct greys)
. Fixed Video7 SL7 inverse text
. Fixed DHIRES mixed mode detection
. NB. Prince of Persia will switch to B&W (560-mode) when going from HGR back to DHGR (same on real hardware).
Video mode: "Color (Composite Idealized)"
. Previously this was "Color (RGB Monitor)" (and before that, the AppleWin 1.25 "Color (Standard)")
. Now this mode does not support the extra RGB cards' video modes
Currently only Apple Color Card and Video7 SL7 are supported.
The RGB card can be defined through the command-line:
-rgb-card-type: apple (default), sl7, eve, feline
The default text color can be modified when SL7 is selected. On the actual card this was defined by dip switches.
-rgb-card-foreground <color>
can be 6 (blue), 9 (amber), 12 (green) and white (15)
Details:
. Added RGB FG/BG Text + mixed GR mode
. Added Color Text80
. Added Duochrome HGR
. RGB card defaults to Apple Color Card + B&W text
. It's an Apple II plus clone.
. The 48K bank-switched Rom is controlled with AN0 and AN1.
. The character generation video Rom has two full character sets: English and German (F10 to switch).
NB. At the prompt, "TEST" runs the ROM self-test.
- 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!
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).
. 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
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).
