Everybody's Golf 2

[the_tobzster]

Hi guys, I'm having a problem playing both Everybody's Golf 1 & 2. The game works perfectly 99% of the time up until I take a shot, I get ridiculously extreme lag. once I take the shot it goes back to normal. Really frustrating as it almost ruins the game experience!
Any ideas on this? I've changed changing settings in the emulater with no luck, so maybe it's the ISO itself I have no idea.
