Emulator Issues #2846
closed
Dual core caused Unknown Opcode (0x4d)
0%
Description
What steps will reproduce the problem?
- Grab latest SVN of dolphin
- Start RE:0
What is the expected output? What do you see instead?
I expect the game to play, but it gives me this instead:
00:40:035 Source/Core/Common/Src/MsgHandler.cpp:53 E[*]: Warning: GFX FIFO: Unknown Opcode (0x4d).
This means one of the following:
- The emulated GPU got desynced, disabling dual core can help
- Command stream corrupted by some spurious memory bug
- This really is an unknown opcode (unlikely)
- Some other sort of bug
Dolphin will now likely crash or hang. Enjoy.
Dolphin version with the problem? Other Dolphin version without the
problem?
I bisected the problem to revision 5699. 5698 starts fine.
32-bit or 64-bit and any other build parameters?
64-bit
OS version and versions of tools/libraries used?
Fedora 13

This happens in dual core mode because the CPReadWriteDistance is invalid. Im working to solve this.

Read the issue, it is about resident evil 0, not Sonic adventure 2 battle. Also try to use the latest dolphin version before making a new issue since the problem might be fixed already without you even knowing about it.
