This week on Battle of the Ports comes the game that inspired the modern 1-on-1 fighter. Please note that I did not include the Saturn and PlayStation MSX collection versions since they based upon the MSX code, not the arcade and since we already have the MSX version featured it seemed redundant. Other versions are not included since they are pure emulation.
