  We report a current status of our radiation-magnetohydrodynamic code for the
study of core-collapse supernovae. In this contribution, we discuss the
accuracy of our newly developed numerical code by presenting the test problem
in a static background model. We also present the application to the
spherically symmetric core-collapse simulations. Since close comparison with
the previously published models is made, we are now applying it for the study
of magnetorotational core-collapse supernovae.
