Description

What steps will reproduce the problem?

  1. Grab latest SVN of dolphin
  2. 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

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.
