I could install the gngeo-gui, some updates appeared and there was gngeogui update, I didn't know I had installed it, anyway, it is done. Sometimes the emulation is under 52/60 fps, but I am getting 23/31 fps now, will run from gngeo-gui, then from Xgngeo, then from the XTerminal to check the differences. Tip for people, leave Raster effect unmarked (configurations), it makes the videos slow. And emulations is better after reboot and overclocked to 800 MHz.
