Looking for Old Dolphin Builds

[catcher40]

Hey i'm trying to find out when Eternal Darkness stopped working in dolphin so i'm looking for really old windows builds to test, so far i have got up to r526 and its still boots the game but i cant find any builds after that until the later r2000+ ones by which time it no longer boots so if you have any older builds between r526-r2000 or even know which revision Eternal Darkness stopped booting can you let me know please.
