I suspect the issue occurs because I used the pext (part of the BMI2 instruction set) instruction to optimize handling of the PPU's CR register. It turns out this instruction is available only on Haswell microarchitecture and newer processors. In case you are using a processor with an older microarchitecture, this should cause a crash.

People who are seeing the crash, can you please let me know if you are using a CPU older than Haswell or not? If this is the case, I will make a solution for this over the weekend.

edit: and btw, mr gopalsr, i can't wait to see a working environment for linux operating systems Smile

I'm using I7-3770k (idk Haswell or not?)

Ooh, okay..my it's "Ivy Bridge", Haswell starts with 4k+ names i think...

ZeCoxao, Darkriot, it looks like you are using Ivy Bridge processors that do not support the BMI2 instruction set. I made a commit a few minutes ago to disable the recompiler from generating BMI instructions. If possible please update your repositories and let me know if the crash is still occurring or not.

Thanks

edit: ZeCoxao, I do not have a Linux machine at the moment. This weekend, I will build a Linux VM and try to fix the compilation issues.

I understand this is early, but it would be nice to make it detect if you are running Haswell and enable the use of BMI2 instruction set in that case.
