Because there has been a lot of questions about the Gamepark Holdings Wiz's dpad, I decided to make a video of the "T-Mode" button test. During the test, I tried to push down the entire dpad, but it will only ever register one direction at any time. I also did a bunch of circles to show how it tracks the transitions. The conversion to YouTube doesn't show it perfectly, but from what I could tell, it seemed to track fairly precisely.
Some folks may remember that the GP2X had a joystick that could be clicked down, and they may be interested to know whether or not the Wiz has this feature. There didn't seem to be any way to press the "center" button on the dpad. This, in my opinion, is the way it should be (for a dpad as opposed to a thumb-stick).
I finally fully charged my battery and the battery indicator shows it at 100%. I had mentioned in a previous post that the "bettery" indicator may be off a bit, but now it seems fine after a full charge cycle.
I also took some footage of a bunch of the built-in GP2X Wiz games. This test unit doesn't seem to have all the built-in games that are advertised to be included. I assume that some weren't ready to be included on the pre-release units. Check here if you want to see the official list of built-in Wiz games that should be included.
I'll leave you with some footage of various games being played under MAME (the Multiple Arcade Machine Emulator).
