I Installed libsdl-1.2.5-slzaurus20030704 and now I can get znester to work properly. I can play ROMs, sound works, graphics seem ok. The only problem is ,I forget where I got the libsdl from, and it only runs in a tiny little window in the middle of the screen. Also, I can't figure out all the buttons.
So, in reality, itstill isn't usable, but at least the roms run. Need a bigger display and key control.
