1.12.7.2 bugs:
. FIXED: BRK opcode only pushes PC+1, not PC+2 to stack
. Rich (news-group): Merlin 8 PRODOS v2.57, type O to save object code, specify name, press return (beep beep beep beep (static, rough sounding))
[Tried with 2.47 & 2.57, but can't reproduce. Have asked Rich for a save-state image just before problem]
. FLASHing in 80-col mode
. VBl IO reg not updated in 'Stepping' mode
--------------
1.12.6.0 bugs:
- I'm using a program that has some key combinations that require that both the open-apple and closed-apple keys be pressed at the same time with a key (i.e. open-apple + closed-apple + q). This works on a real Apple II.
. Numpad '0 + '.' + 'q' works though
. OA + Q = Q (
. OA + CA + Q = nothing
. OA + CA, then release OA, then + Q = Ctrl-Q (145)
+ Alt-Gr: WM_KEYDOWN[Left Control] then WM_KEYDOWN[Right-Alt]
[Win98(+XP?): 'Alt Gr' (Right-Alt) emits a Control key-press before the Right-Alt, so key combinations involving Closed-Apple (Right-Alt) will probably fail. Use Keypad's 'Del' instead.]
--------------
1.12.5.0 bugs:
- FIXED: In 80-column mode, the % character doesn't seem to have a slash at all, just the two dots.
From Oliver Schmidt:
- FIXED: The new tabbed dialog is quite tall - it even doesn't fit on the screen in full-screen mode. Fortunately the buttons are still accessable.
- FIXED: At least with my Windows graphics driver the mouse cursor flickers a lot when positioned over the AW window but not in full-screen mode.
> Does this happen at all times?
Just after booting up master.dsk and sitting "idle" at the Applesoft prompt.
When I try to switch to full screen AppleWin 1.12.5 exits without any
comment. There is no info box (about GPF), nothing. I use Win2K En SP4,
DirectX 9.0c, Matrox G400 with newest drivers
--------------
1.12.4.3 bugs:
- FIXED: Running w/out 6502 DLLs doesn't work (internal 6502 emu code is broken)
- FIXED: When in Apple][ mode, certain games crash to monitor:
. BurgerTime, Ultima3(MB version)
. Don't know when this bug was introduced
- Joystick Config: {Mouse, Disabled} -> {Mouse, Keyboard} does not work.
- FIXED: Incorrect chars: ~, `, {, }, %.
--------------
1.12.4.1 bugs:
- Need to check this:
> I'm using AppleWin 1.8j and trying to create a player disk to save my
> character in Ultima I. I have a valid blank disk image created and
> formatted (I think!), but no matter what I do, I get a 'Disk drive

Reply1:
1: It is an emulator problem.
Reply2:
I had this. I believe I just re-ran the calibration and it went away.
However, there are more recent versions of AppleWin available.
- FIXED: PAUSE emulator. Emulator runs at full-speed for a while after un-pausing.
- Screen-saver kicks-in while playing game which only uses joystick input (ie. no KB or mouse).
- FIXED: "Situation critical" game: key response is slow (fine with TK3000e).
- FIXED: "Olympic Decathlon" game: letters scrolling onto screen are jerky (fine with TK3000e - VBL?).
- Johnson Lam's Mock1.dsk still isn't 100%.
--------------
1.12.4.0 bugs:
- FIXED: CPU usage is 100%
- FIXED: Turning mocking board support turns Apple speaker off as well.
- Oliver Schmidt: I personally don't like the "adjusted" hires colors ;-)
- FIXED: Disk][ speed can be very slow.
- Disk speed test utils still show meaningless results (even with enhanced disk speed turned off). Check with Locksmith 6.0.
- FIXED: FLASHing text in mono-mode.

07/08/04: IanH@cableone.net
i found a crash bug. in full screen , if you move the mouse up and down the right side of the screen, it crashes without a message. i'm using win2k w/ sp4
17/05/04: Joshua Bell [mailto:inexorabletash@hotmail.com]
The calibration on first boot seems to have some issues on Windows XP Pro. This is frequently reported to the newsgroups. I haven't been able to figure out why. If you can get past the calibration it works just fine.
16/05/04: rfoxwell@wso.williams.edu [mailto:rfoxwell@wso.williams.edu]
- Win2K, DirectX9.0a & "Turtle Beach Santa Cruz" soundcard: MB output results in a horrid squeals/beep sound.
+ Sent a new build of AW (w/MAME AY8910 code). This resulted in a crash: "AW has generated errors and will be closed by Windows".
09/02/04: HeavyMetalBCAD@aol.com
Whenever I run AppleWin in full screen mode it always eventually
messes up (usually when i go to switch to a new game). Basically what happens is
it shuts down, or minimizes itself preventing me from keeping it full screen.
I've tried a couple different versions of the emulator but still have the same
problem.
30/01/04: Keith Weisshar
- The delreg.inf actually deleted the current user key and file assocations but failed to delete the local machine key. The last line should read HKLM,Software\AppleWin, not HKLM,SOFTWARE\AppleWin. The registry key is case-sensitive. Could you please change the SOFTWARE to Software in the last line of the delreg.inf file.
- The original delreg.inf file didn't delete the AppleWin registry for the local machine because you also forgot to end the last line with the return key. Each line including the last line must end with a return in order for the command to work. I edited the delreg.inf file with notepad and when I move the cursor to the end of the file the cursor was sitting at the end of the last line rather than the next line where it should be. The CRLF is missing from the last line in delreg.inf causing AppleWin to fail to delete the local machine registry key.
18/01/04: Keith Weisshar
- Why do I get an error AppleWin is unable to initialize the sound card when I try to reconfigure the sound to use the sound card. I have a Crystal sound chip built into the motherboard. I'm running Windows Millennium with DirectX 9.0b.
+ -m switch fixes this.
- Why does AppleWin run very fast on my AMD K6-2/300? I just downloaded AppleWin v1.12.3. I tried recalibrating the emulator but it still runs too fast. Is there any way to slow it down to the original Apple II speed?
16/01/04: Andreas Wirooks
- Soundcard doesn't work with 1.12.x (DX9.0b), but works with 1.10.4
+ Added -m switch so DirectSound isn't init'd

Coding Conventions for AppleWin
===============================
History:
v2 - 16-Feb-2006 (TC)
. Updated after discussion with M.Pohoreski
v1 - 04-Feb-2006 (TC)
. First draft
-------------------------------------------------------------------------------
Introduction:
-------------
This doc defines a very simple set of coding guidelines to be used for AppleWin.
This ensures consistency & readability throughout the project, when worked on
by multiple developers.
-------------------------------------------------------------------------------
1) Project files:
1.1: Each module to have corresponding header
EG. Debug.cpp has a corresponding Debug.h
This is for shared vars, enums, structs, classes, etc.
1.2: AppleWin.h to only be used as per 1.1
1.3: Common.h to be used for any common definitions
EG. const/enum/struct
Obviously not for global funcs or vars.
1.4: .cpp files can drop the AW_ prefix
EG. Rename AW_Mockingboard.cpp to Mockingboard.cpp
1.5: PCH (stdhdr.h)
Could ditch this.
Does this gain anything for such a simple project?
-------------------------------------------------------------------------------
2) Coding Style:
2.1: Naming
The following simplied Hungarian style must be used:
Prefixes:
a : array
b : bool
e : enum variable
g_ : global
h : handle
i : iterator (eg. UINT, STL-iterator)
m : STL map
m_ : member
n : int
p : pointer
r : reference
s : string
sg_p : singleton (could also use 'sgp' - to be reviewed)
u : unsigned int
v : STL vector
Tags:
_e : named enum definitions
_t : struct/typedef
Legacy:
dw : DWORD [legacy: existing 'dw' to be replaced with 'u' prefix]
sz : string (null-terminated) [legacy:
EG:
enum MODE_e {MODE1, MODE2, MODE2};
MODE_e eMode;
struct PAIR_t
{
UINT uA;
UINT uB;
};
Simple loop counters (i,j,k) don't need to adhere to this style.
Don't go Hungarian-mad (you might argue that we already have :)
. an array of any type can just be prefixed with 'a'. Eg. Array of bools:
bool aFlags[NUM_FLAGS];
. a pointer to any type can just be prefixed with 'p'. Eg. Pointer to array of bools:
bool* pFlags;
Naming for parameters that are being modified (eg. OUT):
It is recommended (but not mandatory) to use a suffix of OUT or '_', eg:
bool Find(int* pFoundOUT);
bool Find(int* pFound_);
2.2: Matching braces
These should be have same indentation, unless the braces fit neatly on one line.
EG:
for (int i=0; i<10; i++)
{
// Some code
}
2.3: Scope of module vars/funcs
If module vars/funcs aren't wrapped in a class, then declare as static if not global.
2.4: const/enum favoured over #define
Try to use const/enum instead of #define
2.4: Use of bool over BOOL
Always use bool instead of BOOL
2.5: File header
Just description of module
No copyright or other (legal) notice to be used
2.6: Indentation
Tabs favoured over spaces.
2.7: Expression to be well spaced and parenthesised
It is recommended (but not mandatory):
. to have/use explicit parenthesis
. to have spaces between operators
Eg:
. Prefer: z = ((a + b) + 1) instead of: z=((a+b)+1)

AppleWin 1.12 history
=====================
This version of AppleWin is based directly on Oliver Schmidt's 1.10.4 source.
In an effort to distinguish any subsequent releases I make from the other
variants of AppleWin, my release numbering system shall be 1.12.xx.
Tom Charlesworth
tomcharlesworth AT blueyonder.co.uk
Restrictions/bugs:
- SSI263 emulation is very basic: there is no attempt to emulate rate, inflection or filters.
- Win98: 'Alt Gr' (Right-Alt) emits a Control key-press before the Right-Alt, so key combinations
involving Closed-Apple (Right-Alt) will probably fail. Use Keypad's 'Del' instead.
- During Mockingboard playback, Speaker emulation isn't precise
- Speech emu is broken under WinXP (and Win98 too?)
Acknowledgements:
- Debugger rewrite by Michael Pohoreski
- TV emulation mode by Thomas Stahl
- SSI263 phoneme samples from Chris Foxwell (still missing phoneme #0!)
- Harddisk card: source module & f/w by Robert Hoem

- Fixed DELREG.INF
- Reset now switches Alternate char set off
- PC's delete key maps to Apple's DEL key
- Fixed characters: '6', '|', '_'
1.12.3 - 04 Jan 2004
--------------------
Changes:
- Added Thomas Stahl's TV emulation mode: "Color (TV emulation)".
Tested with Karateka, Mindshadow.
"As you probably know, many of the higher sophisticated Apple ][+
games made use of the blurr-effekt that color TV-monitors had on
patterns consisting of horizontal color stripes. Using this effect it
was possible to produce *solid* mix colors like grey, purple, pink,
yellow and aquamarine even in the 2+ *hi-res mode*."
- Included Thomas Stahl's adjusted hires colors:
He "adjusted the hires colors for a more realistic look -
at least in comparison with an Apple PAL-System."
- Changed wording in Config dialog: from "Color (optimized)" to "Color (text optimized)".
- Fixed Config dialog (speed settings were misplaced in 1.12.2).
- Fixed Joystick 2 for Mario Bros: Now when in dual-joystick mode, 2nd joystick
button controls both switches #1 & #2 as one.
- Fixed Mockingboard IRQ frequency problem (Ultima 4 & 5 tunes now play at correct rate).
- Added Applewin.chm to release zip. (NB. This hasn't changed from 1.10.4)
1.12.2 - 05 Jul 2003
--------------------
Changes:
- Added support for 2nd joystick.
If the 2nd Apple joystick is enabled, then the buttons are re-configured:
- Joystick 1 controls only button #0 (ie. not button #1 too)
- Joystick 2 controls only button #1 (ie. not button #2)
This is so that player 1 can't affect player 2's controls.
So there is no way to control button #2 via a joystick. I don't think this will be a problem.
Of course Left Alt, Right Alt and Shift still activate the 3 buttons.
NB. Disable 2nd joystick if playing a 1 player game that requires the use of buttons 0 and 1.
Tested with Archon I, Archon II and One-on-one.
1.12.1 - 24 Nov 2002
--------------------
Changes:
- Changed tone waveform from orthodox square-wave to a more logarithm shape,
based on real MB waveform analysis. This is by no means perfect, but in my
opinion gives the tones more musical quality.
- Added MB enable/disable switch to Configuration dialog.
- Added simple logging support. If AppleWin is started from the command line
(DOS box) with the '-l' switch, then a text log file, AppleWin.log, will be
generated. This can hopefully be used to diagnose problems some users are having.
1.12.00 - 17 Nov 2002
---------------------
- Initial release.
- Supports 2 Mockingboard cards in slots 4 & 5
- 12 voices and noise supported using DirectX 8.1.
- Tested on Win98, 2000 and XP platforms.
