Jigsaw Madness .bin and .cue files

Can anyone help?Downloaded Jigsaw Madness. Used win rar to extract file (as usual) but instead of getting a .nds file I got two files - a .bin and a .cue. Not tried them in daughter's ds but bet they won't work.How do I convert that format to .nds ?Thanks ;D

Jigsaw Madness is a PS1 game. You can't play PS1 games on the DS.

Ok - I'm an idiot. I usually check as well! Thank you.
