save file help

I use an Original R4 with Wood as my firmware which saves games as .nds.sav and I want to convert it so that I can play it on No$GBA. I tried the shunyweb save converter but that didn't work unless I'm not doing it right or missed something, please help. This may sound noobish to ask but could i just change the filename from .nds.sav to just .sav?EDIT: I just fixed it all by myself, so whoever is in charge here can remove this thread or whatever.

Just make a copy of your save and rename it to gamename.sav then place it into the battery folder basicly.Also be sure the name of the ROM and Save Match.
