Greetings from Spain - Metal Slug port for Atari STE
« am: Fr 26.11.2021, 12:27:45 »
Greetings mates, lovers of Atari,

Some years ago I acquired a never used, a brand new (non opened box), Atari STE computer.
That is really a great machine, heavily underrated machine.

Quickly I update it with 4 MB SIMM RAM modules... and I started on the search about how to program for it using C language...
some time after I reached this state:

This demonstration illustrates many of AGT libraries features, such fast sprite drawing routines, frame slipping, smooth scrolling and dualfield colouring technique, in order to increase the number of colours far beyond 16 usual ones.

It is designed and running on a standard 8 MHz Atari STE with 4 MB RAM at 50 frames per second. Loading from diskette is granted, but hard drive or new sd card reader is easier and recommended.

Due to games developed on this way requires plenty disk space; this demo loads up to 3.61 MB of data, 652 KB of them are used for music and fx effects, other 700 KB are needed to store the extremely detailed NeoGeo quality level map graphics; the rest of them are for sprites; where many animations are not yet programmed, but these frames are being loaded.

Sound is completely based on digital sound samples, mixed in a Real-Time manner; 3 voices at 12,5 KHz, arcade sound quality. The Yamaha YM2149 is not used in this example.

Please, excuse me for the usage of english; I have little to no knowledge of German

Original game code is not used here. Game code is programmed on C language using STE oriented libraries, the digital audio mixer is written on 68k assembly.

Original Metal Slug name, graphics and sounds/musics are property of their respective owners.


Edit: I located the correct presentation section, sorry  :)
