Run T-Rex, Run!!! for Oric
==========================
About:
------
This is a simple side-scrolling game for Oric-1/Atmos/Telestrat/AtmoStrat.
Basically it's a remake of the Google Chrome secret hidden game, which is available when the browser runs in off-line mode.
More information about the original can be found at:

... and a "hacked" version for on-line mode or for other browsers here:

Rules:
------
The Game is very easy - run, jump or duck!
Technical:
----------
Altrough the game looks unpretentious, it uses some unique techniques:
* 2 pages switching for smooth animations: The render "engine" uses 2 pages - one in Text mode and one in Hires. After every new frame is updated pages are quickly switched.
* Automatic vertical synchronization: Using 50/60Hz attributes with special calculated timinigs at startup allows to catch the vertical retrace and to initialize VIA's T1 properly.
* Two different render routines are used for Text and for Hires drawing.
* The standard character set is used for sprites. Some chars are redefined on-the-fly for every new frame.
