Ocarina of Time has been crashing for me without exception. The specific part at which it crashes is where you fight a lone skeleton knight in the Forest Temple, beyond the paintings of the red Poe. It crashes at what would have been the killing blow.

The error message I get is
Unhandled R4300i OpCode at: 801F1000
Unknown 7C 7C 0D 2F

Stopping Emulation !

I'm using a Radeon 9600 XT, 512 SDRAM, Win XP Pro, P4 2.0GHz.

However, I doubt it's the graphics, since I've tried the encounter with several different graphics plugins, and they all gave me the exact same error.

Here's my two cents:

1. Update your graphics card drivers.
2. Get a new ROM.

The video card has nothing to do with unhandled opcodes.

Read this (http://www.pj64.net/main/content/view/404/110/) first. If everything there checks out try different self-modifying code settings (check latest GameFAQ). OOT is known to cause problems for certain people, myself included. Change Memory and Cache has always worked for me. Your mileage may vary...

I tried a different ROM, and I was able to get past the part without a crash, however, I experienced some severe and abnormal framerate drops every time a skeleton knight was killed. I am usually getting a consistent 60 FPS for the entire game, cutscenes, and all. However something about that one part just doesn't like being emulated.

turn off all the cheats, sometimes they cause issues with the opcode

I wasn't using any cheats. Actually, just a few minutes ago, I put in the code for the subscreen delay fix, and I think the sound is a little different for some reason I don't understand, but I could just be going crazy.

You must be using an older version; the subscreen delay was fixed in v1.6. That cheat shouldn't even be on the list.

I confirm that in 1.6 version there is no more crash with OOT rom. There are still some few glitches but none of them make the game hardly playable. I remeber horrible glitches in 1.4 version...:bouncy:

It wasn't in the list. I had to add it in manually. And I am most definitely using 1.6.

I don't know, maybe I'm getting some kind of different result? When I hit the start button, I see a white screen for a few seconds, and then the menu loads. With the delay cheat on, the white screen is more of a white flash before the menu loads. Is that the same issue? Or is it some kind of coincidence?

The subscreen delay cheat is built into the RDB, so there is no need to add the cheat manually.

The white flash appears to be a plugin problem, as on the real N64 there was no white flash.
