Finally got around to testing these last night. I tested the oficial version first, then the 156 and 166 overclocked versions. The officila version worked nicely. What I don't understand is the overclocked versions didn't have the same menu screen or rom selection screen, or even pressing start + select didn't bring up a menu screen like the official version does. What I get is a small color bar running horizontal across my screen. Through this bar shows the roms I can select. I can select a game and play it, and it does seem faster than the official version, but like I said, the button config is messed up, I can't access the menu system by pressing start+select, etc. I was under the impression that the overclocked versions would beEXACTLY the same as the official version, just w/ a speed up. Can anyone shed any light on this? Do I have messed up overclocked files?
