Thanks so much, right there on the page I missed completely. 16 bit has to be the trick.
Which is sad...I'll have to wait for physical device I guess...I've been working on some 800 x 480 games but using nice 24/32 bit graphics
It will serve nicely for lots of non-graphic things and for "backwards compat" testing for things I target the A81/CE 6.0 with.
Thanks so much for the emulator.
