GEMINI is a widely used statistical-model decay code which I started developing in 1986 at Berkeley. It has evolved over the years and in this talk I will discuss my more recent efforts to establish systematics of the statistical-model parameters and the consequences for the structure of warm and hot nuclei. In particular I will show the evolution of transmission coefficients and level-density parameters with mass and excitation energy deduced from heavy-ion induced fusion data, and the present difficulty of reconciling these with proton-spallation data. We will also discuss how to marry Intermediate-Mass-Fragment emission and fission into the statistical model to be consistent with experiment mass and charge distributions and the implications for understanding these binary decays in the transition-state formalism. Finally, I will discuss the origin of the odd-even staggering in the predicted Z and N distributions from GEMINI and the appropriate ingredients and physics which needs to be included for a better explanation of these experimental effects.
