I tried to start gngeo-gui with the commands and the fullscreen worked the first time, but when I started on the gui directly it crashed when there was an osd transition (volumen), the performance is similar to fba, just fba is more fluid (framerate constant higher 45/60), but when overclocked to 1Ghz it is good. Still have to try the aes file, I got a neogeo.zip file, when I searched for aes-bios.bin, I think the file should be inside the zip, but can't see now as I don't have zip app, I remember I had it before (zip and rar apps) in the other N900, but now can't find it on App Man... BTW, I discovered something, probably you already know; I was trying to install psx4m on App Man, but was'problems' a file similar to libs 700201005m... was needed and I couldn't install, so I tried on X-Terminal via root apt-get install 'nameofapp' and it asked to install the dependency package without authentications I said 'y' then Enter and it installed ok. Sorry for off topic from this thread.
