Configuration

VisualBoyAdvance.cfg

• Joy0_ * (where * is a number): Enables you to modify the configuration of the buttons based on the wiki values to know which value to put according to the buttons of GP2x.
• frameSkip: modify the number of images which the emulator skips. The higher it is, the faster the emulation is, but less fluid. And the lower the value, the slower the emulation (compared to the GBA). The values can go from 0 to 5; 5 being the default value.
• gbFrameSkip: allows you to modify the frameskip for the Gameboy and Gameboy Color. the values can go from 0 to 5, 5 is the default value, and while it skips 5 frames, it is the fastest.
• video: allows to define the enlarging of the screen of the GBA. the default value is 0 thus screen identical to that of the GBA.
• fullScreen: Full screen mode, strech the image of the emulation to fit in all the GP2x screen.
• soundOff: Activate/Desactivate the sound, you can gain fps if desactivated. 0 to activate the sound other value to desactivate it.
• soundQuality (sound quality): Defines the quality of the sound the values stand for: 1 for 44 Khz, 2 for 22Khz, 4 for 11Khz. The default value is 4.
• showSpeed: displays the FPS. Off by default.
• autoFrameSkip (automatic jump of image): allows to regulate the automatic management of the Frameskip by the emulator. It is activated by default.
