Mupen64Plus Alternative CRC calculation?

Hi,

In the original GlideN64 settings there is an option called “Alternative CRC Calculation” (txHresAltCRC). It is used for older HD Texture Packs (mostly in RiceVideo format). However, I can’t seem to find this option anywhere on the Mupen64Plus core settings on Retroarch. Does anyone know if there is a way to manually change it, or is possible that they add it in a future core update? Thanks in advance
