Download the two BIOS files you need (they are here in a zip file.).

See, no more error message.Īnd now, you can play Playstation PS1 game on your RetroPie. If you need more info, you probably can read here.

And copy it to /home/pi/RetroPie/BIOS directory. May be download them here? You will need to download these three files and rename it to lower case. So, it is best to find where to download and copy these BIOS onto the RetroPie.Īs you can see the default systems does not come with the Playstation BIOS. You still can play the games, but it might have problem. “No PlayStation BIOS file found – add for better compatibility” One problem I found when I launched the game is You probably wanted to create directory for each games. There are many others out there, just find those that is reputable and no-virus.

RetroPie will be intelligent enough to enable the PCSX Rearmed emulator for all the games you placed down here.įor education purpose, I am going to tell you where you can google and download some PS1 roms for experiment. You copy all the PS1 games onto this directory. So, there are some games you would want to play again. So, by right, you can run Playstation 1 (PS1) games on your Raspberry Pi 4 + Retropie. Playstation Emulator on Retropie is using PCSX Rearmed. So, make sure you have proper heat sink, CPU fan to drive those heat away. So, it will generates a lot a lot of heat. Oh ya, we are overdriving the Raspberry Pi 4. Mine does not work on 2147, but it works on 2000. May be set the arm_freq=2000 and try again. OK, if the Raspberry Pi 4 won’t boot, may be is the arm_greq=2147 is too high. I am also trying to get the Nintendo DS emulator (Drastic) to work properly too. You might even play Nintendo Playstation, PSP, Dreamcast and N64 games here. This will greatly improve your Retropie capability. This will tell the Raspberry Pi to overclock the Raspberry Pi to 2.147Ghz, and set the GPU to 750Mhz. Uncomment the arm_freq line, and add in the following. Sudo vi /boot/config.txt (using vi or nano as text editor is fine).

In case you are stuck, reboot Raspberry Pi and press and hold or hit many times the SHIFT key while rebooting to skip the “overclocking” config. You also need to know what you are doing. To overclock the CPU and GPU, you need to edit the /boot/config.txt file. Press F4 to exit from RetroPie into the unix prompt. You can see what is your CPU clock speed using this command. And you can overclock the CPU (Default is 800Mhz) and GPU (default is 500Mhz). All info obtained from Google Search.Īnd only after a few months later, RetroPie came up with the Beta version of RetroPie for Raspberry Pi 4. *This blog entry is for education purpose.
