r25 | 2009-09-17 23:46:49 +0400 | 2 lines
[Issue 4] Fix incorrect int8_t behaviour if compiled with /J flag.
------------------------------------------------------------------------
r24 | 2009-05-13 14:53:48 +0400 | 2 lines
Forgot about #ifdef __cplusplus guard around 'extern "C"', so inclusion to C files has been broken.
------------------------------------------------------------------------
r23 | 2009-05-12 01:27:45 +0400 | 3 lines
[Issue 2] Always wrap <wcharîàž with external "C" {}.
It turns out that not only Visual Studio 6 requires this, but also newer versions when compiling for ARM.
------------------------------------------------------------------------
r22 | 2009-05-11 22:22:15 +0400 | 3 lines
[Issue 3] Visual Studio 6 and Embedded Visual C++ 4 doesn't realize that, e.g. char has the same size as __int8 so we give up on __intX for them.
his should close Issue 3 in issue tracker.
------------------------------------------------------------------------
r21 | 2008-07-17 09:47:22 +0400 | 4 lines
Get rid of these compiler warnings when compiling for 32-bit:
warning C4311: 'type cast' : pointer truncation from 'void *' to 'uintptr_t'
warning C4312: 'type cast' : conversion from 'uintptr_t' to 'const void *' of greater size
------------------------------------------------------------------------
r20 | 2007-10-09 16:54:27 +0400 | 2 lines
Better C99 conformance: macros for format specifiers should only be included in C++ implementations if __STDC_FORMAT_MACROS is defined before <inttypes.h> is included.
------------------------------------------------------------------------
r19 | 2007-07-04 02:14:40 +0400 | 3 lines
Explicitly cast to appropriate type INT8_MIN, INT16_MIN, INT32_MIN and INT64_MIN constants.
Due to their unusual definition in Visual Studio headers (-_Ix_MAX-1) they are propagated to int and thus do not have expected type, causing VS6 strict compiler to claim about type inconsistency.
------------------------------------------------------------------------
r18 | 2007-06-26 16:53:23 +0400 | 2 lines
Better handling of (U)INTx_C macros - now they generate constants of exact width.
------------------------------------------------------------------------
r17 | 2007-03-29 20:16:14 +0400 | 2 lines
Fix typo: Miscrosoft -> Microsoft.
------------------------------------------------------------------------
r16 | 2007-02-24 17:32:58 +0300 | 4 lines
Remove <BaseTsd.h> include, as it is not present in Visual Studio 2005 Epxress Edition and required only for INT_PTR and UINT_PTR types.
'intptr_t' and 'uintptr_t' types now defined explicitly with #ifdef _WIN64.
------------------------------------------------------------------------
r15 | 2007-02-11 20:53:05 +0300 | 2 lines
More correct fix for compilation under VS6.

Make _inline modifier for imaxdiv default option. Use STATIC_IMAXDIV to make it static.
------------------------------------------------------------------------
r12 | 2006-12-13 16:42:24 +0300 | 2 lines
Error message changed: VC6 supported from now.
------------------------------------------------------------------------
r11 | 2006-12-13 16:39:33 +0300 | 2 lines
All (U)INT* types changed to (unsigned) __int*. This should make stdint.h compatible with VC6.
------------------------------------------------------------------------
r10 | 2006-12-13 16:20:57 +0300 | 3 lines
Added INLINE_IMAXDIV define switch.

Added <wchar.h> include to avoid warnings when it is included after stdint.h.
------------------------------------------------------------------------

2. CPU
Bandai SPGY-1001 ASWAN 9850KK003
NEC V30 MZ - fast version of V30 with internal pipeline (16 bytes prefatch buffer) running at 3.072 MHz.
V30 MZ is aprox 4 times faster than V30.
The V30MZ performs pipeline processing internally, performing instruction fetch (prefetch), instruction decode, and
instruction execution in parallel. For this reason, it is difficult to determine what part of the program is currently being
executed by monitoring the output of the address bus for the instruction code fetch.
If there are conditional branch instructions, even in case branching does not occur, the address of the branch
destination is prefetched (only one time), so that further monitoring of the program is difficult.
The V30MZ has 8 prefetch queues (16 bytes).
There are a few other differences between V30MZ and V30 cpu (unsupported opcodes , different flag handling after mul/div).
Timing:
Hblank : 256 CPU cycles
Vblank : 159 Hblank = 159*256/3072000 = 75.47Hz
3. MEMORY
20 bit addressing space = 1 Megabyte. Memory is splitted into 64KB blocks (segments/banks).
Segments:
0 - RAM - 16 KB (WS) / 64 KB (WSC) internal RAM (see below)
1 - SRAM (cart) SRAM is BSI device BS62LV256TC - 256K(32Kx8) Static RAM - TSOP 0 - 70 c, 70 ns (http://www.bsi.com.tw/product/bs62lv256.pdf)
2 - ROM Bank (initial bank = last)
3 - ROM Bank (lnitial bank = last)
4 - ROM Bank (initial bank = last - 11)
5 - ROM Bank (initial bank = last - 10)
6 - ROM Bank (initial bank = last - 9)
7 - ROM Bank (initial bank = last - 8)
8 - ROM Bank (initial bank = last - 7)
9 - ROM Bank (initial bank = last - 6)
A - ROM Bank (initial bank = last - 5)
B - ROM Bank (initial bank = last - 4)
C - ROM Bank (initial bank = last - 3)
D - ROM Bank (initial bank = last - 2)
E - ROM Bank (initial bank = last - 1)
F - ROM Bank (initial bank = last)
Segments 2-$F are switchable using ports :
$C2 - Segment 2 (value written to port is ROM Bank number ($FF means last ROM bank (last 64 kbytes of ROM file) , $FE = last - 1 .. etc)
$C3 - Segment 3 (same as above)
$C0 - Segments 4-$F - bits 0,1,2 and 3 of port $C0 are bits 4,5,6 and 7 of ROM bank number in segments 4-$F . Bits 0-3
are taken form segment number ( for example , IO[$C0]=$4E -> segment 9 contains ROM bank $E9).
RAM Map :
$0000 - $1FFF WS/WSC
$2000 - $3FFF 4 Col Tiles WS/WSC
-------------
$4000 - $7FFF 16 Col Tiles Bank 0 WSC only
$8000 - $BFFF 16 Col Tiles Bank 1 WSC only
$C000 - $FDFF WSC only
$FE00 - $FFFF Palettes (WSC) WSC only
Some games required initialized (?) part of RAM, for example:
$75AC = $41 = "A"
$75AD = $5F = "_"
$75AE = $43 = "C"
$75AF = $31 = "1"
$75B0 = $6E = "n"
$75B1 = $5F = "_"
$75B2 = $63 = "c"
$75B3 = $31 = "1"
4. VIDEO
Screen size - 224 x 144 pixels (28 x 18 tiles)
Tile size - 8 x 8 dots , 16 bytes/tile (4 col modes) or 32 bytes/tile (16 col modes)
Map size - 256 x 256 pixels (32 x 32 tiles)
Layers - Two layers - Background and Foreground (top layer)
Maps locations - Selectable using port $07
Tiles locations - Fixed, two banks - one at $4000 , second at $8000
Map format - Each position in the map is defined by one word:
bits 0 - 8 - Tile number (0-511)
bits 9 - 12 - Palette number (0-15)
bit 13 - WS = unused / WSC = tile bank
bit 14 - Horizontal flip
bit 15 - Vertical flip
Tile formats - Depends on video mode (port $60)
Sprites - Max 128 sprites , limited to max 32 on scanline
sprite format:
byte 0,1 - bits
0 - 8 - Tile number (0-511)
9 - 11 - Palette number (0-7) + 8 -> (8-15)
12 - Sprite window clipping on/off
13 - Priority with respect to the layers
0 - appear between the 2 background and foreground layers
1 - appear on top of both layers
14 - Horizontal flip
15 - Vertical flip
byte 2 - Y position on the screen
byte 3 - X position on the screen
Sprite table is buffered durning frame display.
Probably up to scanline 140 (1238-144?)
Colors - Wonderswan (Mono) is capable of showing 16 shades of gray(only 8 can be selected at any one time)
These 8 shades form a pool from which the palette definition can select shades. There are 16 palettes.
All 16 palettes are used by BG and FG layers , the last 8 are used also by sprites.
Which 8 colors are used for palette generation is defined by ports 1C and 1E- port 1C
defines palette colors 0 - 3, port 1E defines 4 - 7. Each palette selection is 4 bits in
size:
1C : 11110000
1D : 33332222
1E : 55554444
1F : 77776666
(where color 15 is the darkest one)
Ports 20 - 3E are used to define the palettes themselves.
20 : x111x000 - palette #0
21 : x333x222
In color video modes each color is defined using one word,
where bits:
0 - 3 Blue
4 - 7 Green
8 - 11 Red
12 - 14 unused
Color palettes are stored in the RAM (segment 0) , at address $FE00
Scrolling - Each of layers can be scrolled horizontal or vertical using ports $10 - $13
Transparency - Wonderswan - if bit 3 on palette number is set - color 0 of that palette is transparent
Wonderswan color - color 0 of each palette is transparent
Windows - There are two windows - rectangular areas for disabling /enabling FG layer (FG window) or sprites(Sprite window)
5. SOUND
4 Audio channels.
Each channel can play short samples ( 4 bit , 16 bytes ( 32 sampels = 2 samples in byte (bits 0-3 and 4-7))
with selectable frequency = 3,072 *10e6 / ((2048 - N) x 32 ) Hz , where N = 11 bit value.
Location of that samples is unknown.
Volume of each audio channle is controlled by writing two 4 bit values ( for left/right output
channel) into ports $88 - $8B. Master volume is controlled by port $91
(2 bit value = first 'used' bit in master volume output (11 bit wide) , D/A converter can
read only 8 bits , starting from bit set in port $91 , for example if first 'used' bit
is set to 2 , D/A using bits 2,3,4,5,6,7,8,9 for audio output)
Additional (selectable) functions :
- channel 2 - voice - can play 8 bit samples writing frequently data to ch2 volume I/O port
- channel 3 - sweep - two parameters:
- step = 2.667 x (N + 1) ms , where N = 5 bit value
- value - signed byte (-128 - 127)
- channel 4 - noise - 7 selectable noise generators (probably I/O port $8E)
For detailed info please check ports $80 - $91 in section I/O Ports.
There's also Audio DMA (please chec ports $4a - $52).
Transfer rate is 12KHz (HBlank).
I/O ports $4A-$4B and $4E-$4F are autupdated durning data transfer .

8,9 - Checksum = sum of all ROM bytes except two last ones ( where checksum is stored)
7. INTERRUPTS
The Wonderswan CPU recognizes 7 interrupts from the hardware, these are:
7 - HBlank Timer
6 - VBlank
5 - VBlank Timer
4 - Drawing line detection
3 - Serial Recieve
2 - RTC Alarm (cartridge)
1 - Key press
0 - Serial Send
Whether the CPU should indeed take action when one of these interrupts come in
is determined by port B2. The above mentioned interrupts correspond with the bit
numbers of port B2. When an interrupt occurs the corresponding bit of port B6 gets
set to 1 and, if enabled, an interrupt to the CPU is generated. This bit of port B6
will have to be cleared through code when the interrupt has been handled.
Example:
The Wonderswan is set to react to VBlank begin interrupts. Then bit 7 of B6 is set high
and keeps the interrupt line high until the CPU is able to take action upon this interrupt.
A typical VBlank interrupt routine is as follows:
<push registers>
<do some useful work>
out B6,40
<pop registers>
iret
The mentioned interrupts do not correspond with the same interrupt numbers for the vectors
in the vector table. The base for the actual interrupt numbers is set through port B0. If B0
is set to 20h then a VBlank begin interrupt routine must be set at vector 26h. (Base is 20h
and VBlank begin interrupt is 6)
8. CONTROLS - It's easy to check buttons status reading/writing port $B5(see below).
There's required some delay between writing and reading port $B5 ( few NOP-s)
9. Internal EEPROM Communication(?) and 'owner' info structure
I/O Ports in range 0xBA -0xBE seems to be used for serial reading of internal
WS EEPROM (for example - 'owner' info).
0xBA (Word) - Data
0xBC (Word) - Address (calculated probably Modulo EEPROM size (unknown))
0xBE (Byte) - Communication (?)
bit 4 set before reading data
bit 1 set by hardware , when data is ready to read
Example :
mov ax, $1B9
out $BC, ax
mov al, $10
out $BE, al
xor dx, dx
miniloop:
inc dx
cmp dl, 32
jnc bad_data
in al, $BE
and al, 1
jz miniloop
in ax, $BA ; Month and Day of birth
'Owner' info structure :
- Name - 16 bytes ( 0 = Space, 1 = '0' ... 0xA = '9', 0xB = 'A'... )
- Year of birth - 2 bytes (BCD)
- Month of birth - 1 byte (BCD)
- Day of birth - 1 byte (BCD)
- Sex - 1 byte (1 - male , 2 - female)
- Blood - 1 byte (1 - A, 2 - B, 3 - 0, 4 - AB)
Struct size - 22 bytes = 11 reads,
Address range = 0x1B0 - 0x1BA
