FPGA: Remap DMA1 feature bit to avoid clash
...
Reported by the TASBot community, who was immensely helpful in tracking it down.
DMA1 feature bit in the USB enabled firmware was mapped to the same bit as the brightness limit LSB. This lead to falsely enabled DMA1 feature (i.e. active address spaces where a normal game would expect open bus) which in turn broke an arbitrary code execution TAS movie.
