In this second tutorial, you will learn how to properly use a Mayflash Dolphinbar as a generic sensor bar for maximum accuracy instead of throwing it away and buying a new one. You will need to download a "beta" firmware and flash it to your Mayflash Dolphinbar.
There are two main problems with Mayflash Dolphinbar.
First, its proprietary driver makes calibration impossible, forcing the player to drag the crosshair on screen.
Secondly, it cannot be used as a regular IR sensor bar since its LEDs shut down after some inactivity if no Wiimote is connected to it (30s). This was introduced in latest firmware 1.09 which every Mayflash Dolphinbar nowdays have.
This beta firmware allows using a new mode: the IR LEDs are powered for 4 hours straight. Afterwards, they turn off. Since it becomes a regular sensor bar, sync button is disabled in this mode only. You need a separate Bluetooth dongle/chipset to connect your Wiimote. This update is only for newer Mayflash Dolphinbar model (it has a power switch behind, next to "sync" button).
In addition, multiplayer becomes possible instead of one Wiimote per Mayflash Dolphinbar for light gun games because you are no longer pairing to it.
