Thanks 4 your answer .
I finally got both orientations .

I first got a 1915 ipaq with Xscale ( the MMX of mobile cpus ? ) ( couldn't wait for more attractive devices to be availlable or shipped ....Next might be a 22xx series or new Axim ... ) and wish to learn Xscale optimisations/programming and "demo like coding" in general on mobile devices " i used to code on amiga many years ago " give me few months and i might be of some help .

I'm waiting a GP32 also ...

At the same time, one of my first approach might be turning around source code of Mame and its various ports ...

I i can get achievement in routines optimisations ,i'll certainly contribute with pleasure to every project ...

Cheers

Chapaai
