on PPSSPP 0.8.1 Windows 64 bit it freezes on the main menu. Suggestions? Thanks

Have you tried latest Git build which is now at time of writing this: v0.8.1-147-g6ce949a - it has a 64bit version ready & waiting for you to try.

if you still have same problem, go to Settings / System / Untick Lock PSP CPU Speed - And try this, as the game DID not like being forced to run at higher CPU Speeds of which I found when i edited the PPSSPP.ini file to CPUSpeed = 666 instead of CPUSpeed = 0.
The game runs as smooth as silk now.

Yep. The only speed you can force the game to run at without problems is 222 MHz.

Any higher or lower (even 221 or 223 MHz) and the game won't start. At all. You just get a black screen when booting up the game.
