I'd advise you to use the official RetroPie image when installing RetroPie and not some 3rd party image.

@goalieadam said in Display error, can't launch games:

Not sure how to mark as resolved but this has fixed it.

Edit the topic title (by editing your first post) and append/prepend [Solved].

Did, by any chance, use rpi-update on your system ? What kernel version does your system have (run uname -a to find out ) ?

@GreenHawk84 yeah that should work

@mitu I dont think so

Okay, so now I'm getting blanking AND random "No Signal" to the TV. The no signal issue recovers when I exit the game. Could it be my seven dollar HDMI cable?

@mitu of course
Sorry

Sorry, I actually forgot I posted that, my bad!

The TV supports 1080, but I found the solution by hot swapping the unit after booting with the computer monitor. This boot up set the output to the monitors resolution. Once attached to the Television I had a clear and steady picture. Using the video set-up in the Retropie menu I set it up to use the monitors default resolution. I then shut down and rebooted, and the system loaded to the retropie config I had just corrected. Going back into the Retropie menu's video set-up, I was now given the option to change the resolution to television, progressive, at 720, which is where I wanted this to run to allow for portability. I saved and rebooted and the system loaded on the next try. Four reboots later the system is still easily displayed.

@ss3000

Try setting the overscan in /boot/config.txt using:

overscan_left= overscan_right=

Edit: Of course if that works, you may have to reconfigure your RetroArch display settings to accomodate.

OK I don't know if this is the best way of doing this but it seems to be working. The new config files were saving to configs/all/retroarch/config. The retroarch file being looked at is in gba/retroarch.cfg. I simply copied the content of the new config file and overwrote the content in retroarch.cfg with the new data. I kept back ups of the original files in case anything goes haywire. So far it seems to be just fine. Thanks.

@bense2k Yes, no worries. I've been trying to use the HDMI with no screen connected.

@obsidianspider Thanks for the reply =), no that is not the problem. The problem is that the emulator dont use the CVT standard.

@dankcushions Ok thanks my Raspberry Pi is running now thanks!
