NO$GBA - Incredible lag

Im a noob when it comes to emulators so it may just be my tupid mistake or just how it runs but, im trying to play Tales of Innocence on 2.6a NO$GBA and its really, really laggy i havent even gotten past the opening, is there anything i can do?____________________________EDITStrangly enough it just stopped lagging so its working fne now and i can play tales of innocence :D

probably not, what are your computer specs (CPU/RAM/graphics). and can you post a screenshot of your No$GBA options.

It's probably because you had to many applications open at that time.
