Nah, I use the SC OS mainly, video lag in a intro video on one game isn't that bothersome and I use RTS a lot. I use the Y's or DSTT menu when I want to use the big cheat file sytem.
What I do change is the sc-os layout, by having the screens swapped at boot-up (change in globla.ini) and also the info box off. Then I change the layout to small icons and save the menu layout, this coupled with no more than 15-20 games per folder cuts out menu lag and looks very smart.
