Mala Frontend Gamelist Help

[JadeJ19]

Recently i started the project of building a small arcade emulator on my old computer. Everything has went great following guides and such until i got to the Mala front end. I was lost and confused until i found UncleT's  Guide. I followed it exactly and it was going good until i finished and ran Mala. I'm not sure if it was supposed to be like this but my Mala game list shows 1408 games. This isn't what i wanted    on the list are games that i don't have (in ROM files) , some of mine are they're and launch , and some are just plain missing. How do i fix this so Mala shows the game's i have and none other or less ? Please help cause at the moment I'm at the point of     

Thanks , Jade
