Although the game mentions "sound irregularities" on the disc as a result of emulating Majora's Mask on the GameCube, no mention is made of the game freezing. This is a common issue encountered less often when not using the rumble function. The framerate of the Collector's Edition version of Majora's Mask is also lower than the 20 FPS framerate of the original game. The problems could be caused due to the game's reliance on the Expansion Pack. Majora's Mask also presents a high number of graphical issues, such as the blur effect commonly used during cutscenes either not disappear or not loading entirely. As Ocarina of Time does not use the Expansion Pack used by Majora's Mask, less problems occur. It, however, does experience some minor emulation issues, such as lens flares and other special effects not appearing. Both games also experience another issue. Under normal circumstances, opening the inventory menu will capture the screen and add it to memory before opening the menu so it can appear on top of the game screen. Emulators have difficulty adding this image to the memory, thus, the game will appear to freeze for a couple of seconds before the menu opens up. While this image is being removed from memory as the menu is closed, the game also freezes for a short time.
