well no matter... the WINE project is great but I think if a protable library is built well (ie the unix MainWin or GTK etc...) then we won't have to worry about an API port.
The only draw back is that the PPC games will have to be written from the start to support it or modified. I looked at pocket frog for this very reason: It is very fast and already used by many.
I think the best solution would be for microsoft to support a more strict POSIX implementation of WinCE and start using the ELF exec format... but am I dreaming... this is Micro$oft I am talking about.
