I have noticed that changing the freq in SNES9X TYL .3 in the game Chrono Trigger from its default 22khz to 44khz resulted in a full speed game. Which strikes me as odd since lowering the khz on my old comp used to make the games run faster...
Also, there seems to be a layering problem, during battle the damage done is drawn under the unit, and in many menus I can't read anything. Such as shops and the first part of the character selection menu. I also can't see the name I'm entering for a character.
I don't have these problems with uo_SNES9X_0.02y32, Although I do have to set the frame skip kind of high during battles or it runs rather slow. I also have it clocked at 333mhz.
Mario Kart is worse, I need to change the gfx settings to even be able to se anything but my place and the scenery. Not to mention neither plays it at a playable speed unless sound is off.
