Just received my brand new Wiz (the serial information indicates that it's build date was May 5th, so it's pretty fresh). First thing I did was dump a bunch of my old GP2X software on it, but nothing runs. Going through the File Archive at OpenHandhelds I've been pulling down "Wiz" versions of various programs. Some of them work perfectly, or mostly perfectly. Doom runs without music even though I have timidity at the root of the SD card. Quake runs well and looks awesome. Quake 2 looks great, but there is no sound, at all. Mame4All works with the same roms that didn't work on my old GP2X still not working on this one (no surprise there). Some things don't work at all, even though they are listed as for the Wiz - Wolfenstein never leaves the loading screen. Vice Wiz simply returns back to the menu after few moments. Shanghai2x does not work. Rise of the Triad - no dice. Have I failed to install some crucial library that all these games need? Most of the stuff on the File Archive comes with rudimentary, or worse, no documentation, so I'm a little in the dark as to what to expect. I thought this thing was backwards compatible with the old GP2X but my experience has been that not a single piece of software from the old machine has worked on the new one. Are the games that are running built to more up to date firmware, and the old games that are not working now perhaps built to earlier dev releases? The firmware on this Wiz indicates version 1.0.0 and I see no firmware update on the GP2XWiz.com site (at least the english version of the site and I don't read Korean very well.) Any thoughts and comments on this are welcome. I'm feeling like a bit of a pioneer at the moment.
