Help with roms please

Hey guys everytime i dowload my rom and extract it i go to open it using NO$GBA and i get the save data could not be accessed. Please turn the power off and reinsert the DS game card.
Any suggestions? please and thank you

Use no$gba 2.6a that comes with the 'Auto' save-type option.

i found out the problem i had to change the NDS cartridge to Flash 512k bytes for anyone else who gets this simple problem xD thanks though dude

I encourage you to use the 2.6a(if yours is the old version, if not, change it to Auto),
as changing it manually can resulted to another save problem for another games.
