99 Balls

99 Balls is my first attempt at writing a game for the Sega Mega Drive / Genesis.

It has been tested and verified in several emulators for PAL and NTSC, and on first generation Mega Drive hardware via a Mega Everdrive.

How to play:

The goal is to turn all 99 balls on the screen green. Move the cursor with the D-pad, and use button A, B or C to flip the colour of all adjacent balls from red to green or vice-versa. It's harder than it sounds!
