FapTap review
FapTap separates the timing script from the video. Its FAQ and creator guide explain when a script can be saved as a separate file. The product page lists several ways to connect supported equipment.
Check whether the creator permits script export
FapTap’s help says a creator decides whether a published timing script can be downloaded. Its upload guide names the .funscript format and shows that a creator can disable the download option. The script is a separate file with timing instructions.
Choose the connection documented for your setup
PornCornVR describes using a Handy connection key for titles that have a script. FapTap’s product documentation lists browser Bluetooth and an Intiface route alongside named device integrations. Intiface uses a separate app. FeelXVideos names Chrome, Edge and Opera on desktop for direct Bluetooth and keeps that route separate from its app-based connections.
Anabel’s take
I'd check whether the creator had enabled script export before expecting to use the file in another player. If I meant to stay in the browser, I'd pay more attention to the connection method for my device.
