Design ventoy (support for setting different backgrounds for different folders).

[serhat100]

regexp --set=1:name '.*/(.*)$' "${vtoy_iso_part}${vt_chosen_path}"
        configfile ($vtoy_dev,1)/ventoy/isocfg/${name}.cfg
So your code kdr.iso.cfg will still boot ok
Note: kdr.iso must be in the data directory of the partition

thank you so much @nguyen ha thai trong *****
