Recent string theory developments suggest the necessity to understand supersymmetric gauge theories non-perturbatively, in various dimensions. In this work we show that there is a standard Hamiltonian formulation that generates a finite and supersymmetric result at every order of the DLCQ approximation scheme. We present this DLCQ renormalized Hamiltonian and solve for the bound states and the wave functions to verify that it exactly reproduces the large N SDLCQ results. We find that it has two novel features: it automatically chooses the t'Hooft prescription for renormalizing the singularities and it introduces irrelevant operators that serve to preserve the supersymmetry and improve the convergence. This is a first step in extending the advantages of SDLCQ to non-supersymmetric theories.
