I've just upgraded to a Pi 4 and performed a fresh install of the latest Pi 4 install file (md5: 9154d998cba5219ddf23de46d8845f6c). I know this is still a beta, but I've experienced a couple of quite big issues. Is it the build or something I'm doing?
WiFi search initially found about 8 of my SSID name (for some reason). I couldn't connect to any, but now it can't find any SSIDs at all
Retropie has crashed on a few occasions (with 'Retropie has crashed' message)
Can't change resolution from 4k to 1080p because I can't get into the resolution menu - it just stays at the same menu level
Have I somehow got the wrong image or copied it to the SD card incorrectly?
I had similar issues
WiFi - I created the file pre setup so didn't have this, however did notice a lot of repeats in Bluetooth when setting up my sixaxis for PS3.
Didn't get crashing
Raspi-config resolution... I couldn't get into this either although I did get a workaround which helped.
Just wanted to chime in here and say that I had this same exact problem, and this same exact solution fixed it for me. And the weird thing is that I definitely had 5200 stuff working previously. This problem only just started happening for me. Very weird.
@tackett1980 Cool.. you know, I'm just gonna say the difference in bios files might be a wild goose chase.. so only search for mine if you're really bored :P Hopefully the reicast folks will address the build issue with the stable branch on rpi3.
