- lots of hex numbers were not identified in the cheats conversion from the xml, much better now (particularly for the masks)
 - cheats using watches with loops inside are now supported !
 - you could not disable sound, not sure if it was for all drivers but probably. Setting emulate sound = no and then going back to the game was reseting this to yes ! I guess nobody tried to disable the sound for a very long time ! It's fixed, but notice that some games don't like to have sound disabled and you can get errors if you try to do that (in neogeo for example, you get a nice error about the z80 !).
