Well, you gotta love those japanese guys. The retrogaming scene - if you can call it like that - is quite big in Japan. You'll find tons of retrogames in countless shops, which are scattered around the big cities. Comedians are playing NES games in TV Shows. It is so big, that they release Soundtrack CDs of 20 year old games, even today!
Now I found that nice japanese website by accident, which features scans of Saturn games related Flyers. Yes, I know, it's all in japanese and you probably won't be able to read something. But the resolution is very nice, the quality even more so, both the front and back has been scanned and they are full of pictures! What more can you possibly ask for? The Navigation can be a bit tricky, tho. The game genres are in the upper left corner, and always check the lower left corner whilst browsing, since some genres have multiple pages of flyerscans! But nice as I am I also uploaded a little instruction screenshot.
Funny: When writing this post, a great german Sega Saturn information repository came to my mind, which actually also features scans of old print ads as well as some videos and even radio ads! I recommend you check out its download section. The links are as follows...
