gba模拟器vba的源码，c语言写的，结构清晰易懂

Welcome to VisualBoyAdvance version 1.7.2. 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. Support ------- Please support VisualBoyAdvance by making a donation. You can donate money using PayPal (www.paypal.com). Use the contact form to find how you can send donations. Also, it is recommended that you use the VisualBoyAdvance forum on www.ngemu.com message board. Default keys (can be edited in the Options menu) ------------------------------------------------ Arrow keys - direction Z - Button A X - Button B A - Button L S - Button R Enter - Start Backspace - Select Speedup - Space Capture - F12 You can change the configuration above to use a joystick. Go to Options->Joypad->Configure... menu. The 1 thorugh 4 joypads allow you to have different settings which can be easily switched. System requirements ------------------- Fast computer (Pentium III 500 Mhz recommended) and Microsoft DirectX 7 or greater. Translations ------------ Translations can be done as long as you have Microsoft Visual VC++ on your computer. If you just want to use a translation, place the translation .DLL on the same directory as the emulator. From the Options->Language menu, select Other... and type the three letter (or two) language name from .DLL. For example, VBA_PTB.DLL: type PTB on the dialog. These translation files are only for VisualBoyAdvance GUI and messages. Games will not be translated and cannot be translated by the emulator. Skins ----- Skins consist of a bitmap (.bmp), a region file (.rgn), a draw rectangle on the region and an INI file. Once you have the bitmap, you the region creator which can be found at the downloads section of emulator website along with a sample skin. This allows for irregular skins with holes or any shape. Create the INI file like this: [skin] image=<relative path from ini to image bitmap> region=<relative path from ini to image region> draw=<draw rectangle defined as x,y,width,height separated by commas> buttons=<number of buttons in the skin> (optional) Then, for each button with n starting a 0: [button-<n>] normal=<relative path to button normal bitmap> down=<relative path to button pressed bitmap> over=<relative path to button hover bitmap - mouse over the button> (optional) id=<id of button action, menu or emulator joypad button - see below) rect=<rectangle where the button is to be drawn> region=<region to create a non rectangular button> (optional) The id member can be one of the values found under Tools->Customize to have an action button. If the intended use for the button is to open a menu, it can be one of the following values: MENUFILE - The File Menu MENUOPTIONS - The Options Menu MENUCHEAT - The Cheat Menu MENUTOOLS - The Tools Menu MENUHELP - The Help Menu If the intended use for the button is to provide a joypad button, then the it can be one of the following values: A - A button B - B button SEL - SELECT button START - START button R - right L - left U - up D - down BR - RIGHT button (shoulder) BL - LEFT button (shoulder) SPEED - speed up button (emulator) CAPTURE - screen capture (emulator) GS - GS/AR button (cheating) UR - up and right combination UL - up and left combination DR - down and right combination DL - down and left combination Example: [skin] image=gbc.bmp regions=gbc.rgn draw=20,20,144,160 Skins are only supported in DirectDraw and GDI modes and are also not supported in fullscreen mode. To avoid scaling problems, please not the following: GBA screen size: 240x160 GBC screen size without border: 160x144 GBC screen size with border: 256x224 Not using multiples to these values will cause distortion on the image drawn by the emulator. This is not a BUG on the emulator and rather a problem of the skin size. 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. Reporting a crash ----------------- If VisualBoyAdvance crashes, please do the following: 1. Win 95/98/ME: start DrWatson (drwatson.exe) and reproduce the crash. DrWatson will capture the crash information in a log file (.wlg) file that needs to be sent to me. Please also open the .wlg file on your machine by double-clicking and copy the details section into the email. Microsoft made life harder when you migrate to WinXP (or NT or 2000) by not allowing DrWatson to read its old file format. 2. Win NT/2000/XP: make sure DrWatson is the default debugger by executing drwtsn32.exe -i and then recreate the crash. DrWatson will generate a log file that needs to be sent to me (usually in c:\Documents and Settings\All Users\ Documents\DrWatson). Depending on your system configuration, you may be asked if you want to generate a log file. If so, please click on yes.

Costis for his help fixing some of the graphics bugs. Snes9x developers for the great emulator and source code. Gollum for some help and tips. Kreed for his great graphic filters. And all users who kindly reported problems. 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.
