Well for games such as Castlevania whenever I want to access the menu, walk into another room, etc it runs just as smoothly as it did before. However for games such as Golden Sun and Pokemon, every time I enter a room, access the menu, get into a fight, etc I have a 5-7 second delay each time. I never encountered such an issue with Heart Gold/White (Before applying any of retro's updates), I just updated my TTDS with retro's latest updates and though I am overjoyed I can play more games, the delay is a nuisance. I have used the same TTDS card and 4GB Sandisk MicroSD for the longest time. I still have around 500-700MB of free space and the format has been the same. Any suggestions?
