re naming roms

i have downloaded quite a few roms nowmy questions is,is there any way i can rename the rom i have downloadedi.e 3046 - 101 In 1 Games (E)(M6)(VORTEX).nds this is what i have and would like to have it read like thismy numbering name of game1 101 in 1 Gamesits this possible ?

yes, rename it the same way as you'd rename any other file. However, if you've already played the game and have a save file, you will need to rename that too, so both have the same name (But a different file extension).

ok thankyou for your help

YEah, take note of the last bit... i forgot to do that and started a game all over again.
