R4ultra, ysmenu, DLDI , and GBA_Backup_Tool

Okay, here's my question...
i am running an r4ultra with ysmenu on dslite, and i attempted to use gba_backup_tool...
However, when attempting to run it, it continuously said loading. (i have even tried waiting 20 mins!)
so i tried to patch it with a dldi and i have been having trouble finding it...
if someone could send me a DLDI for R4ultra with YSmenu, or tell me what is wrong, i would greatly appreciate it...THXTHillman01

gba_backup_toolI assume you wish to backup a gba game using your slot 2 in you're NDS ?, are save file maybe .If not then don't recommend using the program at allI used my nds lite to backup a GBA game with an R4 original , and it dose work right away , no waiting at all, it also backed up the games in seconds to 2GB micro sd chip .Maybe its just the clone R4 card you have, clone cards have many issues .
