Emulator

Well it is not necessary to run GC or WII games with a BIOS so you can disbale it in the config menu.

This is not the question.
There are 3 warnings that are looping and which needs to be fixed.
Furthermore, there is still 2 or 3 more issues that OpenGL doesn't have in GC BIOS: screen horizontally split with the top part copied to the bottom one, ane "Type 1" and "Type 4" warnings which, I'm sure, have already been reported.
In other words, it would be great that GC BIOS works as well in D3D as in OpenGL.

I got this issue too after enabling 3D on Luigi's Mansion. Any chance that you enabled it too?

I don't have this game.
What do you mean by 3D? 3D Vision? I don't have a 3D display.

fwiw, this happens due to yScale getting some high value like 750 because the BIOS uses an XFBHeight of 3. Since yScale = (dst_rect.bottom - dst_rect.top - 1) / (XFBHeight-1), the resulting internal resolution (EFB_HEIGHT*yScale) is getting insanely big.
I have yet to find out if this is what's supposed to happen...

Thanks for the info NeoBrain. I hope you know how to fix GC BIOS with DX9, or at least that looping message ;)

Issue 2502?

Just enable "Hide Panic Alerts" if you want to suppress the error messages...

Is this fixed by r7538?

@ MofoMan2 > Nope, I have this issue too (from issue 2502) in Dx9 and 11, not OGL, but this is not the problem here.
@ Nolan > Did not try with r7538 but with r7545, and I have the same issues, except that the looping lines are 66, 80 and 101 in FrameBufferManager.cpp in Dx11 (same lines as in picture above in Dx9).
@ NeoBrain > I don't think this is the best way to fix the issue. In the meantime, this is the only way.

BTW, GC BIOS has a verticaly stretched picture, and it is flickering a lot. Tested it with EmuCR compilation (texture rewrite) and with default settings.
