Path3 Masking: Fixed a bug which caused persona 3 not to boot, previous a hack had been put in place to get around this. VIF: Fixed a VIF error with the rare game Realta Nua, now goes through the prologue correctly. Game requires the EE timing hack to get rid of most of the noise (Path3 masking problem with new GIF unit, unfixable). Expecting bugs, I will be monitoring this. git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5147 96395faa-99c1-11dd-bbfe-3dabce05a288
