    Hi VBT,

    Yes. In fact, there is two project.

    First, I'm working on a new video game engine for the Sega Saturn.
    This engine will be release in december 2014 under the MIT licence.

    The second project is a new Sonic which depends on the first project.

    Here is a newer video:

    It looks great, and it's cool that you are still working on it !

    Does your game engine uses SBL/SGL ? Or is it sega library free ?
    Please let us know when your library will be available :)

    Hi cafe-alpha,

    Yes, I use the SEGA Basic Library.
    The objective is to provide an engine easy to use which doesn't required to have special knowledge about the hardware environment :smiling:

    Clearly, the engine won't be (in theory) the fastest or the smallest, but it will allow any C developer to make a game (not necessarily a Sonic) very easily.

    I'll post the link on the forum as soon as the website is up.

    Parallax and alpha blending looks amazing ! And not using SGL is a good point too.
    I hope this will contribute to create more Saturn homebrew games :)

    Thanks vbt :)

    The website is dedictated to the engine (which is not a sonic game engine but a generic game engine for the SS) but I'll create another one for the Sonic Game (I'll provide an iso).

    Btw, I added an new map editor and new samples here: http://jo-engine.org/download/

    This engine is really cool! Tnx for the hard work Johannes :). Effects like alpha blending used on ps1 is hard to add ?

    I pushed a new version with a paint demo and many features for the VDP2.


    I'm working now to add a mode7 feature on the engine.

    When you say mode 7 do you mean line scroll like the demo or do you mean actually using VDP2's rotating planes?
