Raw Photo Processor 64

Looks interesting. I would be interested in seeing how well it does with scanned C41 negs.

According to the developers website (https://www.raw-photo-processor.com/RPP/Overview.html), last version was published October 2014 and “dropped support for PowerPC Macs”, and “Added Mac OS 10.10 (Yosemite) support”!!!!!! I highly doubt it could run on any modern Mac, especially M-series processors.

Maybe I’m wrong, but besides which the GUI looks like something out of a museum! I guess to each their own, but no thanks from me! Just my 2 cents…. Lew

If this is of interest, you might want to try Filmulator. It's modern, up-to-date, and cross platform. It's also released under the GPL, so it's free software (free as in freedom, although it's also distributed without cost to the user).
