masteries Posted October 18, 2020 Share Posted October 18, 2020 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 for extended joystick port is easier and recommended. Due to games developed on this way requires plenty disk space; this demo loads up to 3.1 MB of data, 512 KB of them are used for music and fx effects, other 512 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. 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. 23 2 Quote Link to comment Share on other sites More sharing options...

oakcitycomics Posted October 18, 2020 Share Posted October 18, 2020 This is awesome. But also where did he get the SD card adapter for the extended joystick port? Quote Link to comment Share on other sites More sharing options...

ParanoidLittleMan Posted October 19, 2020 Share Posted October 19, 2020 It looks that Atari STE finally got full attention - 2 latest game projects presented here are for STE . I don't think that it was underrated machine, maybe among some Amiga people. This conversion looks great. And there is horizontal shooting too ? 1 Quote Link to comment Share on other sites More sharing options...

SlidellMan Posted October 19, 2020 Share Posted October 19, 2020 You have an excellent engine so far, and your sound driver is really solid. Just keep at it. Quote Link to comment Share on other sites More sharing options...

Engine is from DML https://www.atari-forum.com/viewtopic.php?f=16&t=31558 (Douglas Little who made e.g. Doom for standard Falcon and later Quake engine...) But masteries did great job with Metal Slug demo! It's look and sound amazing! Especial colors! 1 1 Quote Link to comment Share on other sites More sharing options...
calimero Posted October 20, 2020 Share Posted October 20, 2020 @masteries do you have any website site with your previous games? Quote Link to comment Share on other sites More sharing options...

Not really yet, Many of my past games were released for GP2X or PS2: FireWhip was a great collaboration: https://dl.openhandhelds.org/cgi-bin/gp2x.cgi?0,0,0,0,35,2911 Masteries Runners is a technical demo of a extremely high performance pseudo 3D road engine, I think this can be suitable for STE, but requiring a sprite format without background cleaning: https://dl.openhandhelds.org/cgi-bin/gp2x.cgi?0,0,0,0,28,2917 Also released for PlayStation2: https://www.youtube.com/watch?v=Sjz_zElwVCI A remake of a ZX Spectrum game, "Viaje al Centro de la Tierra" (Journey to the Center of the Earth), incomplete remake sadly; level 2 is complete: https://dl.openhandhelds.org/cgi-bin/gp2x.cgi?0,0,0,0,35,2845 -Recently, I started the development of games in a serious way...

doctor_shred Posted October 22, 2020 Share Posted October 22, 2020 This looks seriously impressive @masteries I'm a big Metal Slug fan on the MVS and never thought I'd see anything like it for the STE! I'll follow this with great interest. Quote Link to comment Share on other sites More sharing options...

Yes, also with the two vehicles xD Obviously by a tiny amount of time, but it resembles very good the original arcade game. 1 Quote Link to comment Share on other sites More sharing options...
