Activating the smooth graphics and disc speed?

[Tjno]

Hi,

Does someone here knows how to activate the Smooth Graphics and Disc Speed properly??? I activate them and after I do a reset on the console they go back to standard! And besides, if I activate them and play a PSX game right after it, i don't see any changes! (I presume the smooth graphics is basicly antialiasing)
Any ideas?

Thanks!
