This game uses Overscan in Mode 0. The video RAM is located in the RAM blocks &0000-&3FFF and &C000-&FFFF. Software Crossfire technology brings both screens together. One screen RAM is to be seen on the upper half of the screen, the other screen RAM is shown on the lower half of the screen. Therefore it was necessary to use the interrupt mode 2 of the Z80. The resoluton in Mode 0 is 208(x) * 288(y) using 16 colors. Beside the Overscan there is another hardware effect. Smooth hardware scrolling is used. You scroll through one screen horizontally in about one second. | This game uses Overscan in Mode 0. The video RAM is located in the RAM blocks &0000-&3FFF and &C000-&FFFF.

This game is a remake of Giana Sisters. It runs under FutureOS. Since it is not clear to whom the original copy-right belongs it's not possible to name the Game just 'Great Giana Sisters'. So it has the working title 'Return of the Sisters', sometimes it's called 'Tribute to the Sisters'.
Technicals
This game uses Overscan in Mode 0. The video RAM is located in the RAM blocks &0000-&3FFF and &C000-&FFFF. Software Crossfire technology brings both screens together. One screen RAM is to be seen on the upper half of the screen, the other screen RAM is shown on the lower half of the screen. Therefore it was necessary to use the interrupt mode 2 of the Z80. The resoluton in Mode 0 is 208(x) * 288(y) using 16 colors. Beside the Overscan there is another hardware effect. Smooth hardware scrolling is used. You scroll through one screen horizontally in about one second.
A special 2D / 3D engine is used for the Return of the Sisters. In this case it works in 2D mode. In the case of Gerelakos it works in 3D mode.
Since the game engine uses software Crossfire technology and two 16 KB screen RAMs, the interrupt Mode 2 and some other special features this game is being developped for FutureOS. No other CPC OS provides the needed features.
Sinners
The Graphics (Landscape, Background and Sprites) were created by Tolkin, the sounds (title song, level songs and sound effects) were composed by Kangaroo MusiQue, code by TFM of FutureSoft.
This title is under development and it will probably be released in 2009. Up to now there is no pre-release.
