- option to use BIOS file
- zip/gzip file support
- directory selection for save state, battery and screen capture
- fullscreen mode (selectable resolution)
- video sizes 1x, 2x, 3x and 4x
- graphic filters Normal, TV Mode, 2xSaI, Super 2xSaI and more
- interframe blending support
- same emulation core as VisualBoyAdvance: GB and GBA emulation
- built-in ARM/THUMB assembly debugger
- 10 save states accesible through keyboard

- pause, reset through keyboard
- 16, 24 and 32 bit desktop support
- GDB remote debugging (see below for information)
- auto frameskipping and throttle
- AGBPrint support for development
- RTC support

Compiling the sources
---------------------

See the INSTALL file for compiling instructions. Please note the following
requisites to compile:

- GCC must be 3.x or greater in order to compile GBA.cpp with -O2. Earlier
  versions have a problem during optimization that requires an absurd
  ammount of memory and usually ends up crashing the compiler/computer
- On Windows, Microsoft Visual C++ 6 or later is needed. Please note that
  some of the source code will not compile with the shipped header files.
  You will need to install the most recent Platform SDK from Microsoft.

Installing
----------

The easiest installation is to place all files in the distribution in the
same directory.

Per game settings
-----------------

Version 1.5 introduced the support for per game settings for GBA games. You
can defined the following settings on a per game basis by using an INI file
called vba-over.ini in the same directory as the emulator:

rtcEnabled=<0 for false, anything else for true>
flashSize=<65536 or 131072>
saveType=<0 for automatic, 1 for EEPROM, 2 for SRAM, 3 for Flash or 4 for
EEPROM+Sensor>

Use the 4 letter game code to separate settings for each game. Example:

[ABCD]
rtcEnabled=0
flashSize=65536
saveType=0

[ABC2]
rtcEnabled=1
flashSize=131072
saveType=0

FAQ
---

See online FAQ for more information: http://vba.ngemu.com/faq.shtml

Please don't email about what you think it is problem before consulting
the FAQ.

System requirements
-------------------

Windows: PIII 500Mhz machine for GBA emulation. GB emulation requires far less.

Linux, MacOS X, BeOS:
  SDL (>= 1.2.2) runtime library must be installed prior to running the
  program. You can download it from http://www.libsdl.org

Key combinations during emulation
---------------------------------

- F1...F10: load save state 1...10
- Shift+F1...F10: save state 1...10
- Alt+1...4: auto-fire A,B,L,R
- Ctrl+1...8: enable/disable graphical layers (BG0, BG1, BG2, BG3, OBJ, WIN0,
  WIN1, OBJWIN)
- Ctrl+N: pause on next frame
- Ctrl+R: reset
- Ctrl+P: pause
- Ctrl+B: rewind (if enabled and available)
- F11: enter built-in debugger
- ESC: exit emulator

GDB support
-----------

VisualBoyAdvance now provides GDB remote debugging support. This gives
developers the full power of GDB to debug GBA applications.

In order to use this, you will need a cross-compiled GDB for either the arm-elf
or arm-thumb-elf target (used for the --target= option of GDB configure
script).

You can also use GDB frontends like DDD, CodeMedic, etc... or even GDB/Insight
for GUI debugger (if using anything other than GDB/Insight, please make sure
to point to the right GDB executable).

The emulator provides two transport protocols for remote debugging:

- TCP: allows debugging through TCP using port 55555 (or any specified) port.
  The advantage of using TCP is that it allows true remote debugging but it is
  slower compared to the pipe method (pipe method does not work on Windows -
  probably a restriction imposed by the CYGWIN port of GDB).
- PIPE: allows debugging through a PIPE between the emulator and GDB. This is a
  lot faster than TCP and recommened on Unix systems.

Using TCP transport
-------------------

To use the TCP transport, use the flag -Gtcp[:portnum] where portnum is an
optional port number to be used instead of 55555. VBA will wait for a GDB
connection on the specified port (printed on screen). Start GDB by passing the
.elf file, then connect to the emulator by using the command:

target remote <hostname>:<port number>

where hostname is the host where the emulator is running and port number is the
printed port number.

Using PIPE transport
--------------------

To use the PIPE transport, start GDB with the .elf file to be debugged. Connect
to the emulator by using the command:

target remote |<full path to VBA>/VisualBoyAdvance -Gpipe

Debugging with GDB
------------------

Once you connected to the emulator, you can set breakpoints and debug the
application. But before doing that, you will need to issue the loda command on
GDB to load the code into the emulator. Optionally, you can pass the ELF file
on the emulator's command line (along with the -N option to not parse the debug
information in the emulator) instead of issuing the load command.

After connecting and optionally loading the file into the debugger, you can
start debugging: add breakpoints, step, etc...

While using GDB, any console output (see below) will show up in GDB's console.

If you want to break into the GDB, press F11 and it will give you full command
in GDB again. Pressing ESC will terminate emulation.

You can also detach GDB from the emulator.


Console Output
--------------

There are two forms of console output in this version:

- Mappy style dprint: use the following code (from Mappy's documentation)
  to get output:

- VBA style: use the following code to get output:
  // THUMB code
  void print(char *s)
  {
    asm volatile("mov r0, %0;"
                 "swi 0xff;"
                 : // no ouput
                 : "r" (s)
                 : "r0");
  }
  // ARM code
  void print(char *s)
  {
    asm volatile("mov r0, %0;"
                 "swi 0xff0000;"
                 : // no ouput
                 : "r" (s)
                 : "r0");
  }

When using GDB, the output will show up in GDB's console. When using the
built-in debugger, output will go to standard out.

Built-in debugger enhancements
------------------------------

The built-in debugger has the following enhancements (need debug enabled ELF
file):
- ELF file support: both multiple and regular. Please report any messages or
  problems reading ELF files. C++ classes and some miscellaneous features are
  not supported yet. Also, method names may be mangled in C++ code.
- break command: add a breakpoint on a function, line number of file:line
  number
- locals command: print the local variables on the current function
- print command: prints the value of a given expression. Valid expression
  include *this, ptr->member, var.member, array[0], sizeof(expression), etc...
- symbols command: list information known about a symbol (or symbols that start
  with the given name)
- radix command: sets the output radix to eithe decimal, octal or hex.
- file and line number when stopped: the debugger will show the file and line
  number (if available) for the current address
- fixes to some breakpoint handling problems
- fixes to break on write function

Profiling
---------

VisualBoyAdvance has profiling support. It produces output in the format
supported by GPROF. You need a cross-compiled binary of GPROF (binutils
GNU package) compiled with --target=arm-thumb-elf (or similar).

The output will always contain the histogram of PC positions at the specified
frequency even if the code is not compiled with call graph support.

In order to enable profiling, you need to add a call inside your code
to start it (download vba.s for a ready to use file for GCC):

void monstartup(u32 lowPC, 32 highPC)

This will start profiling for the given address region. If the code was also
compiled with -pg, call graphs will be recorded.

Other calls for fine grain control:

// control profiling
// 0 - stops profiling
// anyother value starts it
void moncontrol(int mode)

// stop profiling and output gmon.out file
void moncleanup()

// record call graph (used by GCC)
// r12 contains previous caller
// r14 contains function that was called
void mcount()

GCC bugs
--------

All versions of GCC previous to the working version 3.3 have bugs when
generating profiling for thumb functions.

The errors are:
- movtip,lr not a valid instruction (typo in gcc/config/arm/arm.h)
- LPxx undefined when linking (missing . before LP causes the problem)

You can fix these problems by either recompiling GCC (recommended) or by
modifying cc1.exe to fix the problems.

In the first option, find the given code in gcc/config/arm/arm.h and fix
the typos (remove the extra blackslash from the mov ip,lr instruction and
add the missing dot before LP%d) or change THUMB_FUNCTION_PROFILER to call
ARM_FUNCTION_PROFILER (the recent changes that were performed in CVS).

If you don't want to compile your own GCC, then you can use an hex editor
to fix the problems. Locate cc1.exe under <dir>/lib/gcc-lib/<config>/<version>
and find the movtip,lr instruction. Change the extra backslash to a space.
Locate the .LP string just before the mov instruction and change it to
.P instead (make sure to place 0 after the P). Then find the text .word
LP%d and change it to .word .P%d.

Histograms will be output even if the code is not compiled with call graph
support.

Options configuration
---------------------

All configurable options are accessible from the configuration file
VisualBoyAdvance.cfg.

This file is searched in this order:

- current directory
- user home directory (defined by HOME environment variable)
- user profile directory (Windows only defined by USERPROFILE directory)
- executable directory (either relative or defined by PATH variable)

All options are documented in the file supplied with this distribution.

Contact
-------

Please don't email unless you found some bug. Requests will be ignored and
deleted. Also, be descriptive when emailing. You have to tell me what version
of the emulator you are writing about and a good description of the problem.
Remember, there are several interfaces (Windows, SDL and GTK+) and
several systems (Windows, Linux, MacOS X and BeOS).

Also, there are still people writing about the old VisualBoy which is no longer
supported. Also remember I am not paid to work on VisualBoyAdvance. This is
just a hobby.
