Hey, I was going to do some fan-graphic design but couldn't find any high res PNGs on a quick Google search. I probably didn't look very hard though tbh. So if there are already tons of similar logos out there, then fair enough, never mind.
Either way, I ended up making my own. They're not perfect but if you scale them down to normal web-sizes they should look ok.
I'm posting them here so people can be free to use a high-res logo however they wish. In youtube banners, twitch overlays, facebook, twitter etc.

And here's a fanart boxart I did for good measure showing all graphics together. Shows how they look scaled down.
Edit: If anyone is looking for something specific let me know in the replies. Like if you want a twitch banner at A x B dimensions with image C and the logo in the middle etc.

I made this as a christmas present for a friend, and there's lots of sega fans here so I suppose I'll include it here. Feel free to use it, or get a print of it etc. if you so wish.
