It&#8217;s a game console from just a ATMega644 mcu and a\u00a0AD725 (RGB-to-NTSC converter) chip. Thats the whole idea. The RGB signal is created by a manual 3:3:2 resistor based DAC, and audio is pure PWM signal.<\/p>\n<p style=\"text-align: justify;\">The awesome part of this console is the &#8220;kernel&#8221;, written by Uze (Alec Bourque), which has several video modes available, and a 4 channel audio mixer, all done in interrupts, so that when you code stuff to this console, you don&#8217;t have to think about the clock cycles of your code, as the interrupt will always update the screen and audio output &#8220;behind the scenes&#8221;.<\/p>\n<p style=\"text-align: justify;\">The project is now also supported well by a small but great community, that has helped Uzebox with more video modes, games, and even a realtime emulator!<\/p>\n<p style=\"text-align: justify;\">I have made a few additions to the emulator (uzem), adding threading to split the SDL screen blitting from the MCU emulation in seperate threads, a funny RAM\/Progmem visualizer, and a SD card FAT16 emulator.
