Why are embedded functions created in 2012 changing to s functions when model used in 2010?

I have a model that was created in Matlab 2012. I am creating a HIL system with it using dSPACE and, since I only have licenses for 2010 dSPACE, I have to used 2010 Matlab. Upone tranfering it over to 2010, the embedded functions in my model were changed to s functions. Why is this and how can I revert it back to an embedded function without just creating another one? Thank you.

AFAIK, (Embedded) MATLAB Function blocks have always executed by generated C code from the MATLAB code in the block. This C code is interfaced to the model via an automatically generated S-function. You should see that even in your newer version of MATLAB, there is a MEX-file generated for the model containing Embedded MATLAB Function block(s).
