Start with 10 Credits (Japanese version)
This code only works in the Japanese version that originally starts with 4 Credits. At the Acclaim logo screen when Goro appears, press Left, Up, Right, Up, Left, and Up. You will hear a sound right when the screen fades away after the code is entered correctly that allows you to start with 10 Credits.

How to attack Goro without making him unfreeze
It's possible to hit Goro without making him unfreeze! First, use Sub Zero's ice blast
attack to freeze Goro. Now, quickly run up to Goro and do a few (3) sweeps. (Back + low kick) This attack does not make Goro unfreeze! However, do not be too greedy and try more than 3 sweeps on Goro as he can simply unfreeze by time.
To maximze damage after freezing Goro, sweep him 3 times and than do an Uppercut attack! (down + Hard Punch)
