A set of publicly available SDSS simulations are 
included here,

http://sdssdp62.fnal.gov/sdsssn/SNANA-PUBLIC/SIMULATIONS/SDSS/

These sims include SNIa + SNCC, and also include both the 
spec-confirmed and photometric subsets. The input files are
included so that you can re-simulate with modified parameters.  
See AAA_README (in the URL above) for details.
