not sure exactly, i think it could be the n64 itself. try using the 'reference rasterizer' or/and the frame buffer emulation, and maybe it'll work how it should. other than that, not too sure.
No, it isn't intentionnal. I have not been able to go where the ss above had been taken (inside Zelda'castle I suppose) because my saves are further in the game, and I don't want to erase one.
But everywhere I've tested that, you can see the water when the camera is under.
This shot was taken inside the Deku tree. Even when Link isn't in the water, you can see the water surface when the cam is under. (btw, the web does not look good).
I went inside Zelda's castle, and I have the problem shown above. It seems to be the only place where this occurs though. blush: but I forgot to make a save state) So it may be a bug in the game, not in the emu.
