There is for the save file. See the Boot options page in the FAQs.Is there any commands I can add to the grub to make it load the save and .sfs files placed in a folder and not the higher level of the directory?
Example grub entry:
title Fatdog64-610 (on /dev/sda6)
rootnoverify (hd0,5)
kernel /610/vmlinuz savefile=direct:device:sda6:/610/fd64save.ext4
initrd /610/initrd
The savefile argument means to use a savefile named fd64save.ext4 located in /fd610 directory of /dev/sda6, save directly to it.
EDIT: Just saw rcrsn51's post. Ditto on the Menu > Control Panel > Utilities > Savefile Argument Builder.
