Hi,
Is there any development area that is badly needed in AROS? If I don't get any suggestions I will put $50 into the 64-bit porting, which I think will be impressive.
Aren't you a little late for 64bit? Michal has had the x86-64 build up quite a while and it is very cool

Just do what I do and split your donation evenly across the projects that interest you

68k native is my current interest.
