Metal Slug port from Atari STE to MegaDrive / Genesis - WIP
Video of current WIP MegaDrive / Genesis version:
https://www.youtube.com/watch?v=-hl3hkKaHa8
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.
Video of Atari STE version:
https://www.youtube.com/watch?v=gyRBcTnn-5M&t=115s
Audio playback is 100% based on digital samples, using a custom made sound driver that provide 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,
Stay tuned!

Did you see Vetea's version? Interesting timing that both appear within days.

Sonic needs some speed boots there - he's a bit slow...

Metal slug + atari st + megadrive...
Nice bunch of key words.
Your demo shows pretty good stuff!

You must be quite excited waiting for your release.
Congrats for this job!
How long should last the definitive port? Single mission or whole game?

I played this demo a couple of times.
I noticed a Marco's respawn bug, if interesting.
Music sounds really rough to me, this would be the very only issue to your artistic stuff.
I must play arcade to much. I realized the autofire at the very end of the test.
Not a single lag..!
That's pretty awesome demo.
Keep on working Masteries.
