Well i have this problem with all versions i tryed so far , including the lates stable and latest SVN revisions. So i played WWE All Stars yesterday and today allmost 3-4 hours with no problems at all , perfect fps , perfect picture , everything was perfect and suddenly the emulator gives no respond error and i can't open the emulator , when i click it , it just flickers for a less then a secound and the icon just stays at the tasckbar unclickable , restart of the pc didnt help and this happens with every version i tryed so far with the emulator v2.0 , r7435 and the latest that i didnt even remeber the number , when i DL a new one , again everything is normal till the point this error again occur and i loose any progress i made so far with the game 
and can you tell me where the emulator saves the progress from the game? I mean the save that you make in game , not the savestates..
Is there any solution for that? The emulator is great , the game runs great , i would be sooo gratefull to any kind of help ..
some log info if this could bring any help for you
