@Pietze I'm not able to see the game art on the game lists (I've downloaded the NES pack and placed it on ~/.emulationstation/downloaded_images/nes/, is that enough?)
@simonster I have a NTSC set, With component it's the reason I'm using the YUV Transcoder all my other consoles is using Scart cables via a Scart Switch. Some how I eliminated the squeeze picture issue and ran into other problems with Retroarch not saving menu settings. And I can't get cores to run at all. I would down load them but they will not show up.
@CrossCheck The advXYZ set of utilities (including the emulator) are installed in /opt/retropie/emulators/advmame/bin - see Advmame. You'll have to run them from a command line, outside of EmulationStation.
Now, finally I found another image from the retropie facebook grp... tried it and BAM, no more color problems!!! Wth?
Guess I need to compare the configs since this last one was pre-configured for crt.
