up the development.\nWe will replace them by pure public domain code when we will have enough resources.\n\nFeatures include :\n\n- i386 and \"custom\" architecture\n\n- Graphic framebuffer (standard: 640x480 monochrome)\n\n- Keyboard + Mouse or touch screen \n\n- (USB or SDcard) Mass Storage (FAT32)\n\n- Audio Device (mono 8kHz/8-bit in/out)\n\n\n\n![qemu](doc/screenshot.jpg)\n\n## License\n\nSee
