Hey!
..I just provided a new patch for the PAL integration, upgraded everything to the latest SVN, Revision 243 before. It will probably cause many problems to integrate this one and should be seen as starting point for a PAL integration, there is definitely more to be done. But hey, it works here so I can provide help, if needed!

I will create a better patch as soon as possible.
