So I've been reading about the history of these carts. Quite obviously, everyone who has submitted a run has done so on an Everdrive or emulator. These pirate carts were originally developed in China and sold in Russia. Both of these places use the 220v / 50hz power type, as opposed to the NTSC 115v / 60hz type. The Dendy (and European NES) run at a slower clock speed to account for the difference. This likely means these runs are being done at an abnormally fast clock speed. This may also apply to other Hummer Team titles using similar mappers, such as Somari, Kart Fighter, etc.

While Dendy and Pegasus, the two most popular famiclones run at a peculiar NTSC with forced 50Hz, most famiclones do not. The games themselves work natively on Famicoms. Also, there is no standard famiclone. Several clones have different graphical chipsets and architecture. Some are NOACs that don't run even these games. Unfortunately some clone carts cannot be played on a standard Famicom but this is solely because various wires are bodged together because most clones use bad mechanism to read carts. Dumping such games, they will then work natively with no issue on Famicoms.
