Hehehehehe,this is had happen to my tobal 2,but it has been fixed:
so, what must to do ?,
1. open the ePSXe excutor, find the setting that you use for VP,
2. go to the options, set the COUNTRY SETTING to PAL,
3. and set the Fps limit GPU (pete's) to 60. just that.
try to run the Tobal2, if the game runs perfectly, then try the VP,
4. if the problem solved, contact me!
use the bios DLTH-3002/yaroze (it may be faster for some games)
