You mean provide some compatibility modes to allow the less tricky software
(Ie not copy protected games etc) to function etc, but do other things by
direct hardware access, or have some nice utility routines in the ROM too,
to make creating custom software easier.
Ie things like BUS enumeration, initialisation, resetting, reading/writing
addresses of the buffer etc. etc. So the programmer never has to touch bare
metal.
