Frédéric MANTEGAZZA and Laurent DIEUDONNE (his cousin) are the authors of an Amstrad CPC game edited by Lankhor : Fugitif. Drawing are by Jean-Paul RENAULT (read the description on CPC-POWER about the drawing, it's interesting), music by Laurent MOLLARD and box cover by Stéphane POLLARD.
It was made in mode 1 using rasters to show more than 4 colors. Frédéric has lost the original source code, so he disassembled the program and commented it (download available).
For more details, read the AMSnews article on the game.
Frédéric is working on a new release of Fugitif, to address the main issue of the original game: at the time, he was unable to do anything else during the raster display. The new release will use demomakers tricks to display a hud below the image. This hud will non longer be icons-based, but rather a console, whith a syntax interpreter, as in many adventure games in this era (and something he originaly wanted to do). The game will be translated in other languages.
