So the logos are complete, but i don't know how to do them work with custom art mode. I have created folders xlogo_m, xlogo_sk and etc.. in renfe and render folders but i couldn't get them work. Strange thing is that xcommon, xovrlogo and xfescr logos work, and even xlogo_sk in renfe folder work, but i can't get work xlogo_m, xlogo_s, xlogo_f and xportbck logos. If someone knows the answer what i am doing wrong, write here.
As for now the only way they works is to import them into viv files.
I will release them today or maybe tomorrow.
