Alternatively - have you tried Reye's tank-game convertor?
GitHub - ReyeMe/ModelConverter: Simple converter for some of my games
He's done a couple Saturn games already, of course Tank Game, but also SkyBlaster. I downloaded this ages ago, but never tried it - it appears to have a much easier path from Blender to Saturn (it comes with a Jo-Engine library, examples, and a game demo!). I wish I had tested it sooner because it looks promising.
Maybe there's a newer version of XL2's tool; his engine is awesome but not everyone has access to it. I did get his tool to work at least, but it wasn't easy. I just want to put Sweet Tooth on the Saturn, lol. Not reinvent the wheel
🙂
edit: I don't think it supports textures - but maybe that is something that could be expanded on? at least it works, lol
I didn't set up anything in Blender regarding lighting etc, so I assume that's why it looks wrong - but this took me the same amount of time it took to write this post to get this model from Blender to the Saturn:
@SuperReye - any comment? what would it take to add texture support to your tool? I assume it's flat-shaded only because it's quick/easy. also, flat shaded actually looks really great if done correctly.
edit2: it does support textures.. it says so right on the github, duh. It doesn't support UV mapping, which I get since the Saturn doesn't either, but that would make conversions from other programs easier. maybe that's what I meant!
