[edit] How Do I Install Emulators, Games And Other Applications?
Unlike Windows applications, which tend to install themselves, there is no need to do that with Wiz applications. Simply unzip the archive it comes in, consult the README file and then copy the required files to a folder somewhere on your SD card. Then, if using the default Wiz menu, you simply select "Launcher", navigate to the applications folder and select the "appname.gpe" file.
However, not all applications are the same and these instructions may not apply to all of them but generally following these will work and any extra information required will usually be supplied in a README.
[edit] How Should I Organize My SD Card?
One efficient way is to make a few folders in the root of your SD card with very generalized names. For example, one such folder structure may be:
- Applications
- Books
- Emulators
- Games
- Movies
- Music
- Photos
Inside each, it may be best to keep everything categorized for easy and understandable access to your Wiz applications and media.
[edit] How Do I Get The Menu Back Up In My Emulator?
There are many emulators released for the Wiz and these button cominations change all the time so it is best to check the README file for your particular emulator which will certainly contain this under the controls section. However, if you are unable to do this for some reason then here is a list of the most common emulators and their key combinations used to get back to the emulator menu but keep in mind it may not be entirely up to date:
- Dr. PocketSnes - Press the Volume +/- at the same time.
- Picodrive - Press the "Select" button.
- MAME4All - Press the L + R + "Select" buttons.
- GPFCE - Press L + "Select" buttons.
- VICE - Press the "Select" button.
- gpSP - Press the "Y" button.
[edit] The Touchscreen Is Inaccurate, Does This Mean My Wiz Is Faulty?
The short answer to this question is no. The first thing you should try is going to the Wiz "Settings" menu and selecting "Calibration". Then follow the on screen instructions to recalibrate your touchscreen. This should help but if it doesn't entirely alleviate the problem then the remaining inaccuracy is likely caused by the present immaturity of the Wiz firmware. For reference, at the time of writing the current Wiz firmware version is 1.1. Sometimes, one-sided pressure from the case can cause inaccuracy. In this case, try softly pushing the case onto the device, through putting light pressure onto spots left and right of the screen. This should only help if there are gross inaccuracies.
Changing the Wiz clock speed by Overclocking or Underclocking is known to cause issues with touchscreen accuracy.
[edit] Why Are My Video Files Not Playing Correctly On The Wiz?
An expanded port of Mplayer by Ikari is available which has support for H/W YUV 4:2:0 Layer, Overclocking, subtitles, multiple file formats, and several additional features over the built-in Wiz player. It is available on the Wiz Archive at OpenHandhelds.org.
Currently the built in Wiz video player only supports videos compressed using either the MP4, DivX or XviD codecs. Furthermore, even if a video file uses the correct codec for compression it may still not play back correctly on the Wiz if it has a resolution that too large relative to the screen's.
If your video files do have issues during playback then try re-encoding them to use one of the correct video codecs and have a resolution of 320*240. A resolution larger than this does not yield any benefit when played back on the Wiz. Furthermore, MP4 playback is rather haphazard in the current (version 1.0) Wiz firmware so for the best playback performance it is best to use either the DivX or XviD codec with an AVI container.
[edit] Is It Safe To Overclock My Wiz?
Yes. Overclocking your Wiz is perfectly safe, though it may marginally reduce the life of your Wiz console. Selecting a clock speed that is too high will cause the system to freeze, crash, or restart
A large majority of Wiz handhelds can be overclocked to up to 800Mhz with no ill effects.
