Why is xemu banned from the boards? I tested the whole game out on it today and it has no issues or slowdown to have a major advantage over MAME/Dolphin users.

It also doesn't make sense because the Namco Museum 6th gen leaderboards itself have Xemu as an accepted platform for emulation on Dig Dug Arrangement and high scores.

The only "issue" I came across on xemu is the title not loading the correct graphics, loading a white rectangle.
