Add support for Operation Stealth PC 16 and 256 color versions with AdLib and Roland MT-32 sound. Add support for 20 extended savegames (Thumbnails, playtime etc) for both Future Wars and Operation Stealth (20 because it fits on screen using the original save/load interface). Details: - Add versioning to Future Wars and Operation Stealth savegames. - Add fade in effect to both Future Wars and Operation Stealth. - Add mouse wheel support and keyboard support to moving in menus. - Map middle mouse button to pressing both left and right buttons. - Make interface more responsive (See manageEvents() and drawFrame()). - Amiga versions should be completable but sound may or may not work. - Atari ST versions completely untested. Game options currently supported: - Using original save/load interface - Using transparent dialog boxes in 16 color scenes (Also for PC) Console commands currently supported: - labyrinthCheat (For cheating in Operation Stealth's labyrinths) - disableLabyrinthCheat (Disabling labyrinth cheat) - disableHacks (Disabling hacks, useful for testing) - enableHacks (Enabling hacks, useful for testing. On by default)
