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

 johannes Oct 16, 2014
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

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.

johannes, i'm happy to see your engine is still in progress. the video is looking really promising.

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

Hi everyone,

I finaly finish the website : http://www.jo-engine.org...

I still need time to finish the tutorial and samples, but the engine works great

 vbt Nov 8, 2015
hi, great job johannes, i will compile everything, why don't you provide ready to use isos?

 johannes Nov 15, 2015
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 ?

 johannes Dec 9, 2015
Hi luisoft,

No, it's not hard when you know how it works

Btw, a new version is available on the website

 vbt Dec 10, 2015
great job johannes, got the new version, i'm ready for testing

 johannes Dec 11, 2015
Hi vbt,

Don't hesitate to email me if you have any problem.
The engine isn't finished yet, but the basic things should works.

Hi,

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.

Bye,

 johannes Dec 28, 2015
Hi,

A new version is now available with mode7 support and better performance

Everything is here : http://www.jo-engine.org/download/...

here comes a new challenger
nice line scroll, i was hoping for a up/down too, maybe next time good job !

 johannes Jan 3, 2016
Up/down and rotating is working too, I will add another sample

 TrekkiesUnite118 Jan 5, 2016
When you say mode 7 do you mean line scroll like the demo or do you mean actually using VDP2's rotating planes?
