masteries Posted October 19, 2021 Share Posted October 19, 2021 (edited) Greetings mates, I am starting with the port of the Metal Slug version for Atari STE, to Genesis / MegaDrive system For anyone that didn´t know anything about the Metal Slug port for Atari STE: https://www.youtube.com/watch?v=gyRBcTnn-5M Nowadays, in Genesis / MegaDrive, the first mission map uses up to 64 colors, while sprites have up to 32 colors (2 palettes of 16 colours for them) I added a parallax plane to this first map. Sound is the same as Atari STE version, with one additional voice. Totally digital sampled sound and music. These images (19 October 2021) are from the Work in Progress for MegaDrive / Genesis: Excuse the presence of Sonic sprite, this is being used for collision testing Edited October 19, 2021 by masteries 11 1 Quote Link to comment Share on other sites More sharing options...

masteries Posted December 16, 2021 Author Share Posted December 16, 2021 (edited) Following the port of Metal Slug from Atari STE, This time, a brute force sprite test, in order to evaluate the limits of MegaDrive / Genesis hardware The scene of this video is insane from a gameplay perspective, But it illustrates the near arcade capabilities of MegaDrive / Genesis hardware Edited December 16, 2021 by masteries 1 Quote Link to comment Share on other sites More sharing options...
Chilly Willy Posted December 18, 2021 Share Posted December 18, 2021 That certainly was insane. You could see points where the sprites per line limit were hit, but in a normal game, I don't think it would come up. Quote Link to comment Share on other sites More sharing options...

All in all, good luck for your work !! Greetings, Vetea Greetings Vetea, I am using a heavily modified SGDK installation along with a commercial 68K compiler. Video memory management is a custom one, as well game engine is heavily inspired in Atari Game Tools for Atari ST/E Map and colouring tools are exclusively made for Megadrive / Genesis development. Sound driver is a custom one that provides 3 compressed digital audio voces mixed at 16 KHz Sprite collision engine is made from scratch using 68K assembly I have a question regarding Sega 16 forum, some weeks ago I registered in the cited forum, but my account is not yet activated to post replies... How much time It takes? Best, Masteries Edited December 28, 2021 by masteries 1 Quote Link to comment Share on other sites More sharing options...

Chilly Willy Posted December 30, 2021 Share Posted December 30, 2021 If you aren't already registered at SpritesMind, I'd suggest doing so. It's the main hang-out for Sega developers, especially for MD/Genesis. Lots of good technical threads and help there. ? http://gendev.spritesmind.net/forum/index.php Quote Link to comment Share on other sites More sharing options...
