The instructions are not working for including Mame4All into AdvanceMenu.
It keeps giving an "Invalid Arguement" for the first directory location line. I have tried to use the "/home/pi/emulator" path, but it gives the same error.

From thread: http://pimame.org/forum/discussion/524/trackball-issue#Item_4

To change mouse polling, from a terminal: sudo nano /boot/cmdline.txt ... then add usbhid.mousepoll={number in ms} ... to the end.
1000 hz = 1 ms
500 hz = 2 ms
250 hz = 4 ms
125 hz = 8 ms
100 hz = 10 ms

When you use Mame4all as the emulator from the advmenu, the games list shows up as the filenames, so is often difficult to tell which game is which.

To produce a file that can be used by advmenu to give the correct titles, run this command in the Mame4all directory:
mame -listinfo > mame4all.lst

Then copy the mame4all.lst file into the .advance directory.

I've just updated this to include new items and be easier to read, etc.
Tell me what you think :D
