@mitu
Thank you!!!

@sleve_mcdichael said in Where is the Default Theme Font Located?:

@AlphaBetaPie ah, I don't know then because I only ever use it over terminal myself. Log in as root, maybe?

...or add them to a regular folder over FTP then SSH in and sudo cp them via command-line for the "last mile."

Thanks, appreciate the help. I'll keep fiddling with it and if I need more help I'll check back. Much appreciated!

@mitu Discovered my problem. There were actually two theme.xml files that needed editing, the first in the root of the designated theme and a second copy in the retropie subfolder.

Sure enough, modifying both theme.xml files got the font working!

Please provide the rest of the info asked in https://retropie.org.uk/forum/topic/3/read-this-first.

You should upload the gamelist.xml for the system where the faulty files reside, to make sure it's not been incorrectly generated.

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.
