Flashback features fully hand-drawn backdrops and all animation is rotoscoped, giving movements an unusual fluidity.
The game was a commercial and critical success and was listed in the Guinness World Records as the best-selling French game of all time.
This game was officially released for the Sega Dreamcast in 2017, despite the fact that the console is defunct since 2001.
One of the materials in the box of Flashback is a coupon for a rebate on a Gravis Gamepad and a note to "try Gravis' Ultrasound 16-bit sound card." This is ironic because, among Gravis Ultrasound enthusiasts, Flashback is notorious for being incompatible with the GUS.
Programmers might be interested in the fact that Flashback is one of very few games that used a screen mode with a width of 256 pixels. This implies that the address of a pixel on the screen could be comfortably stored in a 16-bit register, say AX. The X-coordinate could then be manipulated through AL, and the Y-coordinate through AH. This might have contributed somewhat to Flashback's impressively fluent animations.
