Fix bad boolean handling

A boolean is not guaranteed to be either 0x00 or 0x01, it can have any other value. This holds true especially when the compiler starts optimizing. Therefore, a boolean should never be bitshifted, but instead you should act on its value.

This is a fix for a bug I encountered on actual hardware...
