Here’s some issues I found with your log that might help.

  • Enabling Accurate Multiplication is recomended for accurate emulation.

Take a look at this PR, it explains the motivation for that hack but it was removed after canary-1041, from my testings SMB4 was one of those games that would benefit from it, in this case with higher internal resolution with performance degradation.

You can read there why it was removed, you can also test the canary build mentioned above to see if that works for you to.

Thanks, now I understand why that happens and that its not a problem on my end. The build you posted works great, but i like using the latest version, so I’ll stick with it.
