Why is the NIOS I core now missing from the sopc builder in a legacy build that needs to be rebuilt?

Hi Abraham, Thank you for the response. I checked with the customer and they say they have now tried using quartus versions back as far Quartus 3.0, and still are not able to see the NIOS 1 library. Only the NIOS II shows up. It seems the SOPC builder is not independent from quartusII in the early versions so they aren’t able to individually roll back SOPC versions from quartus. Or maybe I’m missing something. The goal of this effort is to change some wait state parameters in a legacy design that was built with NIOS 1. Are there any files they can hand edit to update sram wait states without invoking the actual tool?
