There are 2 modes in the game, Story and Database In story you choose where to go like North America, South America, Europe or the Middle East Then you watch slideshow of images which I assume are from the manga of Golgo 13 with voiceover of the characters and then at a certain point you are given a choice to where Duke Togo should do nexts and any wrong choices will mean Game Over
Database is basically quizzes about Golgo 13
Although there was someone who dumped it before me, they only dumped on redump.org which does not share the .cue/.bin files and only tells you of the disc data
