Rockey 4 is far more advanced then u think and Rockey 5 and 6 used well leave no option for hacking. Rockey 4 dongle can include beisides data u can store in dongle a user algo zone where u can store small algos. That zone is write only so is little chances fix that if author used it. Anyway if u like i could take a look at to see how it works. Anyway before start such thing i suggest good understanting of their sdk.
