It's based on an ESP32 and an 2.4" ili9341 Display. If modified the nesemu code from Espressif. I've added multi Rom support and a little Menu with sound-, fullscreen- and brightness-settings. Fullscreen can cause graphical glitches and it has very bad sound. But it's fine for me...maybe i'll try in the future to add a save- and load-function.But all of this is coded very dirty... :D
