Revision as of 21:11, 16 February 2009 by TFM (Talk | contribs) (To explain it: If you use the lower block as screen RAM and scroll it, IM 1 is just not usable. This is not a demo. You should know all these things :-)))

Preview of the castle scene, presented at the XzentriX 2006 meeting

Overview

Gerelakos is a Role-Play-Game (under construction) for the CPC. Tolkin and TFM are working since 2005 on it. First Preview was presented at the XzentriX_Meeting_2006 an can be downloaded on the gerelakos homepage.

This is the story of Kane and his quest through different worlds.

Technicals

This game uses Overscan in Mode 0. The video RAM is located in the RAM blocks &0000-&3FFF and &C000-&FFFF. 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 or vertically. A 3D engine is used for Gerelakos. 

The game engine uses two 16 KB screen RAMs, the interrupt Mode 2 and some other special features. It is developped for FutureOS.
