Fun School 3: For the Under 5s
The CDTV version. It's about 2mb while the normal version is around 700kb (most of the extra space is the manual I think... I did check, but forgot, but... ye, think it was the manual... can't be bothered to re-check... ye, not important... but still... *burp*... excuse me, just had pizza and 1L of Coke Zero). It has a title screen with a lame voice message, a manual, a bit different look to the menu, uses arrow keys/joystick instead of the mouse, question button for help, you can select difficulty levels, and maybe some other stuff.
