If editing files around is not something you're familiar, then my suggestion is to find a system with a bit more performance and has the righ GPU. Even if you'd manage to get EmulationStation working, other programs/emulators might have similar requirements and you'd be struggling to make it work.

@mitu Fixing the case sensitivity worked! Thanks for your help.

@jerryfudd It's a raspi-config configuration error. Modify the /etc/systemd/system/getty@tty1.service.d/autologin.conf file and replace its contents with [Service] ExecStart= ExecStart=-/sbin/agetty --autologin pi --noclear %I $TERM then restart your system.

wow!thanks all you guys! I fixed this problem.i used those command： sudo apt-get update sudo apt-get install fonts-droid-fallback sudo reboot and i changed theme‘s font file to chinese font. ps: If you rom file name not enghish,DO NOT use usbway to copy roms.Because the rom name will be like that：“？？？？”no matter what you do.

No. I use a True Type font. The gamelist font on my theme has some screen tearing. Some extra dots by some letters. On my Windows ES there is no problem. V-sync? Use of SVG? VRAM? Use of other font? Changed it all? Btw. RetroPie is on a Ubuntu PC with a NVidia card. I will send a photo from the thing. Hope somebody had a similar problem with the solution. Thank you.

Damn, I read the whole thing but didn't check the "important links". Thanks a lot @EctoOne, I was completely lost. I will check with another font.

Just thought i'd mention it here. OTF works natively. No need for conversion.
