Hi


I changed calls for do_put_mem_xxxx ; other places are often using 
STMemory_WriteXXXX. So adding a call to flush cache just in this 
function should be enough (that was my plan, but I forgot to do it 
yesterday :) )

See my other posts, it's not related to VBL or video, for some reasons 
it's the cache access / shift operation that shows this slowdown as if 
the code was really not well optimised in that case. Really strange.
