emulator not finding my roms

I'm new to the whole emulator thing and i downloaded no$gba and downloaded some Roms and wen i go to insert the cartridge the files aren't showing up so i need some help on what to do

Put your roms in the SLOT folder...

ok i tried that and the roms are still not showing up

They can be in any directory. It looks for a file with a .gba or .nds extension. You need to extract them from their archive. Read this tutorial :) Once you've extracted them and got the ROM, you can load them like usual, or drag and drop the ROM onto the .exe, OR you can do what I do, and set the .nds file extension to be associated with no$gba (right click any .nds file, then Properties).

thanks for the help it worked
