Super R-Type for Europe and Japan

Version 1.9

This version adds the European and Japanese versions of Super R-Type, all three now built from the same source.

The European version is almost the same game as the American one, so the patch only needed a few bytes changed. The Japanese version is the same program assembled again, an earlier build, so the code sits in different places. Most of the patch moved over automatically, and the few places where the American version added something on top of the Japanese one were adjusted by hand.

On the European version, the opening sound effect plays a little before the ship launches. The original European game does the same, because it was never adapted to 50 Hz.

Games included:

• Contra III v1.2
• Gradius III v1.7
• Super R-Type v1.3
• Race Drivin' v1.1
