100 Yen Disk is a compilation disk featuring following games:
Shooting Master '86: A mix of an adventure game and fixed shooter. To get to the fixed shooter part you have to get through the adventure part though.
Graman Bee: A shoote'em up in space where you have to shoot space worms to get power-ups and fight a boss. Probably a prototype.
Electric Novel: What it says on the tin. An electronic novel, so a lot of text to read through.
The Rotten Wall: A Breakout rip-off.
Jumpper: An endless runner. Jump over the spikes. You have only one life.
There is also "The information of Nao Graphic Lab", which is just some information featuring a MOE schoolgirl.
