Description

Game Name?
Lord of The Rings The third Age

Game ID?
G3AE69

What's the problem? Describe what went wrong in few words.
When I use Jit to play this game it pseudo-randomly crashes with the warning

IntCPU: Unknown instruction 01000000 at PC = 00000008 last_PC = 812fffc8 LR = 80236550

When I use JITL and MMU it works fine (without MMU I cant save), but the game runs at 50% speed, the MMU speed hack helped but was removed from dolphin.

When I say Pseudo radomly, I mean that it will crash randomly while playing, but the game typically crashes when a textbox starts to appear.

What did you expect to happen instead?
That I can play the game normally without crashes.

What steps will reproduce the problem?
1. Start game
2. Load save
3. Play game and randomly crashes within minutes

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
4.0-6221
4.2 stable

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
No, it has not

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
intel 3000 graphics
2.2 QM ghz processor
gen 3 graphics card

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

History

#1 Updated by JMC4789 almost 6 years ago

MMU speedhack is always on now; it wasn't removed it was enabled period. So if it helped before; it'd help now as well.

I did notice it was on, but when I use it with JITL I get another error that says Retrieving unkown spill slot. Then WriteRest op out of range 0x1b9c5877 uses 0x8018ba858

  • Status changed from New to Accepted
  • Category set to ppc

I can reproduce the "Unknown instruction" error with non-IL JIT. Always the same message and randomly but reliably happens the first time you get to walk around.

The "Retrieving unknown spill slot"/"WriteRest op out of range" errors in JITIL were fixed in http://dolp.in/pr2272, but it throws lots of "redundant MOV" errors.

Maybe related: Yummy Yummy Cooking Jam also crashes with last_PC=812fffc8.

#5 Updated by ZephyrSurfer about 2 months ago

I cannot reproduce this even if I have a portable.txt in older builds of Dolphin for some reason.

It's apparently working anyway.
