Some genesis Vc titles don't work

[drhycodan]

Certain games like earthworm Jim 2, revenge of shinobi, and sonic and knuckles don't work with vulkan or d3d.  They give me this error "source[color=#032f62] rect is too large for CopyRectangleFromTexture".  Only opengl seems to load them but they seem more glitchy than the vc titles that load on all backends.[/color]

Nobody knows what this error means?

They use a special rendering mode. OpenGL seems perfectly fine, but, I'll see if I can't report these to get them fixed... again.

Nintendo's Genesis Emulator appears to be our one weakness.

You can enable "Disable EFB2VRAM Copies" in advanced to fix D3D and Vulkan until a permanent fix is found.
