There are some serious shenanigans going on with this install. The icon never works properly, just gives a "Please wait a moment" message in portrait orientation, and then switches back to landscape and quits.
When i try to run prdoom, it fails to find the iwad. The only way to get it to run is to make a symlink to the prdoom.wad in the directory that has the doom.wad in it, and run prdoom from that directory. Otherwise it fails to find the wads. If i try to modify the .cfg in home/zaurus, it still fails to find the wads, and also appears to spontaneously combust afterwards (even if i change it back) requiring a nuke and reinstall of the prdoom package before it will work.
Finally, in order to get it to run in landscape mode (assuming i'm running as described above, from the wad directory), i have to set it in the cfg to run at 640x480, which is pretty jumpy.
I haven't figured out how to turn on and off magnification, but perhaps if i can find a commandline switch to magnify the app, it will work even with 320x200 (magnified).
There are obviously some poor install scripts in one or more of these packages.
Ideas?
