No, it's only some work, see other mail. The dat file is from a port of
nasm (the x86 fpc assembler is based on nasm) to arm but it's buggy and
needs to be updated, luckily enough the arm doesn't have that much
instructions as x86 :)

Yes, I know this from win64: you one case and two others break ;)
