Greetings from Spain,

This Metal Slug port is a conversion from my own Metal Slug port for Atari STE computer

Mainly all the game engine is being ported from Atari STE to MegaDrive / Genesis.

Audio playback is 100% based on digital samples, using a custom made sound driver that provides 3 channels mixed at 16 KHz.
Samples are compressed, in order to save ROM space, and Real-Time decompressed using the Z80 processor.

Currently, the same samples and graphics from the Atari STE version takes only 1 MB of MegaDrive / Genesis ROM space,
while the STE version takes 3.6 MB


There is a high detailed background composed of up to 8600 tiles, and a parallax background.
Background uses up to 61 different colours.
Custom MegaDrive / Genesis tools are made to create map graphics data,
and to provide colouring to the map tiles.

Many things are still pending to be ported to MegaDrive / Genesis,


The idea is to create a Metal Slug style Run&Gun engine for multiple systems;
while the graphics and audio for an incoming new game is being in development

Stay tuned!

Following the port of Metal Slug from Atari STE to SEGA Megadrive / Genesis,
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

Wow, this looks fantastic! Do you think this could come out this year? Also, I don't know how realistic this is, but is there any chance of including local 2 player like the original arcade version? That would be a blast!
