Well I want to transfer my heart gold game save to another Heart Gold ROM, and I don't know how to do that D: Can someone tell me how? I'm using No$GBA if that helps.
Just make sure that save file(.nds) has the same name with the rom(.nds). e.g Pokemon.sav = Pokemon.nds
Your emulator or flashcart will automatically try to use the save file it finds, rather than creating a new one. As long as it is named correctly.
If your save file is from No$gba previously, just rename it. You can find it from your BATTERY folder in your no$gba folder.
When I tried to rename it, it gave me a warning message that it might become unusable if I change it. Should I click Yes or No? (Yeah I know, I'm careful)
When I used my No$Zoomer I opened the new rom I downloaded, but the save file was not there. Was there anything else I was supposed to do?
