Hi,

I just wanted to report that this happened to me too.  I'm also using version 0.8 and am running Mac OSX 10.4.11.

I was trying to run the Harvest Moon rom, and it made my computer run reeeeally slow.  I then clicked into another window and saw that I only had 1 GB of space on my computer when I previously had 3.45 GB or something.  Then it crashed.  I restarted and tested, and noticed that the longer I played the game the more memory was lost (went down gradually, then went back up when the game crashed or I quit).

It takes about 10-15 min for the game to crash.

I was looking in the forum to see how to fix this, but I guess it hasn't been fixed yet
