Star Ruler 2 opcode missing
Hi,

The star Ruler 2 game is mostly launching on box64 on RPI4 8GB, if you let it finish some intense CPU calculation at the beginning, but starting a game fails during the loading phase with an:

`262914|0x4745b5: Unimplemented Opcode (C0 4D 63 C7) 64 F3 42 0F 5A 04 85 BC FF FF FF E9 26 FD FF`

Earlier in the loading, the following message is displayed:

`OpenGL vendor 'Broadcom', renderer 'V3D 4.2'               version '3.2 (Compatibility Profile) Mesa 20.3.5'                                                Failed to compile shader: /mnt/usb/Star Ruler 2/game

-In Shader 'DistantFadedIcon'`

but it doesn't seem to influence the graphical part of the game for now.

Is it an opcode that could be added for further testing?

Thanks a lot
