Folder access needs a supporting desktop browser. You can import a ZIP or add files.
Both modes present complete frames with the browser's refresh. C64 speed preserves PAL/NTSC timing; frames may repeat or be skipped when refresh rates differ. Display speed runs one C64 frame per refresh before audio starts or while audio is unavailable. An active audio device uses C64 timing in both modes, including while muted.
