OK, that's what I started to think already. But how come I can create 8bit, 16bit & 32 bit "A" modes with the Picasso96 tool, but no 24 bit mode, which is supposed to be supported? I guess it's me. But I cannot find any how to guide for dummies like me 
dont worry my CV64 also dont work with 32 bit :-) same like your ,
16 bit is ok
