![]() ![]() Previous models' GPU memory configuration ( Memory split) are not needed for the Pi 4B. The Raspberry Pi 4 model is supported by Raspbian starting with Raspbian Buster (based on Debian 10 'buster'), while RetroPie added support the the 4.6 image version. If you have the official power supply for your Pi 4, you shouldn't have any problems. This has been corrected in the 1.2 revision of the board, released Feb 2020. The first Pi 4b revision (1.1) has a non-compliant USB-C charging port and doesn't work with as many chargers as it should, especially E-marked USB-C cables/chargers. Using a 4k resolution on the Pi 4 is still too demanding when using RetroPie, so if you have a 4k display and you're seeing slowdowns/stuttering the first time you boot, there a few options available to alleviate this issue:Įither use Raspi Config from the RetroPie menu in EmulationStation to set the resolution, or edit the config.txt file on the sdcard and add the following lines at the end: NOTE: If you are using both HDMI ports of the Raspberry Pi 4 for simultaneous 4k video output, you are limited to for both displays. To change it 60hz refresh rate, add hdmi_enable_4kp60=1 to config.txt or use raspi-config to enable the video mode. By default it will select a 30hz refresh rate for a 4k resolution. The Pi 4B can use 4k video resolutions when supported by the display. More details about video configuration options - Video Options in the official Raspberry Pi documentation. Because composite video requires a very specific clock, setting that clock to the required speed on the Pi 4 means that other clocks connected to it are detrimentally affected, which slightly slows down the entire system. IMPORTANT: the configuration comes with a performance penalty. This will disable the HDMI video output, so make sure you remove this option if you change the video output on your Pi 4 to one of the microHDMI ports. Analog videoĬomposite video from the analog RCA port is not enabled by default on the Pi 4B, you need to add enable_tvout=1 to the config.txt boot configuration file. NOTE: The Pi 0 miniHDMI cables are not usable for the Pi 4B microHDMI ports. It's recommended to use the port adjacent to the UCB-C power input (labelled HDMI0) to connect your display, since is has sound enabled by default and it's the only port that supports CEC. ![]() Either of them will be fine for RetroPie, the memory capacity doesn't influence the emulation speed. There are currently a few Raspberry Pi 4 models available, differentiated only by the RAM option - 1Gb, 2Gb, 4Gb or 8Gb. Raspberry Pi 4B specific questions, configurations and differences.
