Drift Diffusion Model fitting toolbox - DMAT not working in Matlab 2020a

I am trying to use the DMAT toolbox GUI for performing model fitting of Drift Diffusion Modelling (used in Neuroscience and Psychology resarch and modelling). This toolbox was written in 2006a Matlab. I am unsure if the makers have maintained the toolbox over the years to keep it compatible with the newer versions of Matlab. So I tried to download the older Matlab 2006a version on my Mac (OS 10.15 Catalina). It did not run and the toolbox DMAT is not running in the Matlab 2020a that I usually use, either.

So, my main question is -

1. How can we get an older version of Matlab to run in Mac? (I think if I can run/install Matlab 2006a then I can run the Toolbox without any issues!)
2. Or does anyone (working with Drift Diffusion class of Models) know how to run the DMAT in current versions of Matlab (e.g., 2020a)

Thanks

MATLAB for Mac R2006a is for 32 bit PowerPC architecture https://www.mathworks.com/content/dam/mathworks/mathworks-dot-com/support/sysreq/files/SystemRequirements-Release2006a_Macintosh.pdf

You would need to use a product such as Parallels to run an older version of MacOS in order to host an older version of Parallels in order to host an older version of MacOS in order to run Rosetta... or something like that.
