Hi everyone,
First off, MameCE3 now has game screens centered in most games !
A few odd ones seem to be fighting the fix, but I'll see if I can WhIP them into shape by the next release. :) Thanks to Darren for his centering code. It didn't exactly work for me but it helped me to figure out where to direct my energy.
FYI Darren, move your centering routines to the Create_Display routine and use a static variable or 2. This will better optimize the draw_to_screen (blit) routines, since Create_Display is only done once when you start the game.

Second, Sound has been fixed in many games! Sound has been cleaned up a bit and I think I fixed the memory leak that was being caused by it (cross your fingers). Unfortunately there is now a discreet hum in the background but it is very low and can almost be ignored now that the sounds work mostly correct in many more games. Mr Do is much more playable now that the sound is working right.
That annoying high pitched hum at the beggining of Donkey Kong turns out to be music :) It is more understandable and I think, if I can fix that annoying low hum in all games, it should also fix the problem in Donkey Kong.
My Sound routines are definitely improving and I will go back to tinkering with them after I fix some other stuff.

Next 2 hot fixes i'll be working on are, Screen rotation and On-Screen buttons.

Thats it for the moment. If things go well expect a new release real soon :)

Cheers,
