You can run gdb and enter in any hex digits you please right before
the PC and go through each instruction step-by-step.

However, if you're interested in brushing up on your assembly and/or
learning more about running code at the machine level, you may want to
install spim which is a MIPS-6000 simulator. There is even a book that
helps one learn MIPS assembly using spim entitled:

This is a standard undergraduate-level textbook.
