So 50% of the time my RBPi2 with RetroPie does not boot, if creates a bunch of errors, see photos below. After a while it stops and does not nothing, when I pull the powerplug and put it back in it usually boots up and I can use it.
When I have used it and I reboot trough the Emustation software it stops working about 50% of the times as well. Pull plug once or twice and it boots correctly.
RBPi2 with RetroPie buzz build from 6th of February (Compatibilty topic Page 4)
16Gb microSD Transcend Class 10
So I tested with a different PSU and USB cable, (i use 220v to USB and then a cable) But the problem remains.
Not sure what you mean here. Have you actually tried a different wall wart completely? The part that actually converts AC wall voltage to 5VDC? If so, then I would try a different Pi next in the list of troubleshooting steps. If that’s not feasible, try a different display, but that is a long shot
