Madilyn's Mad Dash

Madilyn's Mad Dash is a 1990 platform video game developed by Langley Productions and published by Astound for the ; a port for the was released in 1994. It is the first game in the Madilyn series and marks the debut of Madilyn Marvell, an anthropomorphic. It introduced many conventions that would appear in later games in the series. The game follows Madilyn as she goes through six levels to retrieve various artifacts stolen from the Heartlands.

Madilyn's Mad Dash was created by Kevin and Julianne Langley, who intended it to be a simple game that could be easy to pick up and play. To make the game easier for more casual players, they included the ability to edit or max out Madilyn's HP and starting number of lives. To allow advantages for Atari 7800 owners with more than one type of joystick, the game allowed players to switch between "Pro-Line Mode" and "CX40 Joystick Mode" at the title screen.

Development
Madilyn's Mad Dash was created and designed by Kevin and Julianne Langley. Julianne Langley, Matthew Hubacek and Andrew Postlewait programmed the original version of the game. Much of the programming was done using a console equipped with both Expansion Module #1 (which allowed the console to play  games, in this case, it was used to make sure the game could properly work with the  chip, as well as to help write prototype cartridges) and the  Expansion Module #3 through a jury-rigged connection. As Hubacek had lost the keyboard for his Expansion Module #3, an Trak-Ball controller (which was attached to the Expansion Module #1) was used in tandem with the ColecoVision controllers' keypads and an on-screen keyboard to input values; Hubacek described the process as akin to "using dish soap as windshield wiper fluid."

The original Atari 7800 version made use of an onboard sound chip on the cartridge for improved audio.
