Good day!

I've been programming a Sega Saturn game since march of 2017 using the Sega Graphic Libraries and my own engine.
It's not an exact 1:1 reproduction of Sonic X-Treme, but it aims to take ideas from this game and put it on the Saturn.

The game works on stock hardware at 30 FPS - and 30-20 FPS during splitscreen.

Here it is in action (WIP) :

Been seeing this kicked around a couple Discords I'm in, and gotta say, it looks super impressive! Don't know a lot about programming, but I know the Saturn is (was?) a pain to work with so to have this much running is astounding. Hope you'll keep us updated!

This looks amazing so far. It looks more like what I imagined X-Treme to be as a kid. Meaning, it looks better than the playable builds that came out a few years earlier turned out to be.

I'm really impressed that you have it running on the Saturn itself. I didn't even know that Saturn homebrew was a thing.

Wow, that's some really impressive piece of work.

Quick! To the time machine! :v:

This is amazing! I've subscribed to your channel and look forward to more updates. It's not everyday you see Saturn homebrew, especially based around Sonic. :)

Already looks more playable than Sonic X-treme ever did :specialed:

But seriously nice work. I look forward to seeing more of this.

This looks really impressive. I curious what Andrew75's thoughts on this are.

I am curious about what the code and project structure for a Saturn game like this looks like.

I think it looks good ! We've spoken on YouTube about trying to get one of the levels that I had recreated in the past sent over to test in Sonic Z-Treme. I been waiting for my Jo-Engine account to activate for the past few days, Seems its activated now, and next time that I'm at the development computer, i'll be sending over the files that were prepared a few days back. Most likely this evening.

As far as audio, are you going to stick with purely sampled audio? Or are you gonna attempt to work the Saturn's internal synth?

So far for audio things are pretty broken, but my todo list is so long that it falls back to lower priority for now. I will probably stick to sampled audio, but I will need proper 11025 hz files (or just convert them properly). The Saturn got 8 audio channels, but currently the PCM files I use are filling 33-50% of it's capacity even if they are mono and downsampled. I'm not sure if it's a bug with Jo Engine or if it's a bug on my end (I haven't put much efforts in this yet), but I limit audio playback at the moment to 1 file only to prevent overflow crashes. I could work around this by coding a better audio implementation, but right now I want to focus on creating tools for windows to convert levels (such as those shared by Andrew75), bin-loader, mesh-loader, auto-generate the BSP and collision detection boundaries. Everything was handcoded, which takes way too much time.

Hopefully - if I'm succesful - I could put several levels from Sonic X-Treme (and the truly amazing conversions made by Andrew75 for Project AXSX) into my engine. I will probably have to remove some details in levels to reach 60 FPS (some people will disagree with that, but I think it's worth it).

Of course, I'm always happy to receive feedback and hints, so if you have suggestions for the audio don't hesitate!

This looks like a pretty good project. If I had a saturn I'd give it a go. That's for sure.

I have a modchipped Saturn so if you get a lot done and do a release in any stage, I'll be glad to be able to play it on real hardware. That will be amazing when Andrew75's PC version and your Saturn version are both done. What's cool is that there will be 2 different takes on how the game would have been. It's kind of like how there are alternate takes on how Hidden Palace Zone and other scrapped Sonic 2 levels should look.
