You can use any software that work with the conventional model, as the zero sum game efficiencies can be calculated directly from the conventional ones according to Bouzidis, T. and Karagiannis, G., 2022. Extending the zero-sum gains data envelopment analysis model. Journal of Productivity Analysis, 58(2-3), pp.171-184. and others.

You can use any software with LP function, like Python, Matlab, and R. Actually, I have been using R to construct DEA models. I think most people tend to choose Matlab, but you can use the software that you are familiar with

Majid Zadmirzaei

There are no limitations to run your model with common OR softwares. Nevertheless, GAMS would be more efficient ones, and MATLAB and R (DEA package) can be used as well.
