D008B1B8 0108
80007800 4D43
D0007800 4D43

it did not work when i pressed R1+select to start the no random battles

so what could be wrong then

I have no idea how to get this no random battle code to work for lunar 2

Maybe you have a outdated version of gameshark.

Those are simple if.. then write codes. Shouldn't be a version problem.

I think I remember that code not working long ago when I had a PS1 and gameshark pro. I don't know why it was never caught before.
