If only you could do it without AI.
Viewing post in Xevious for Sega Genesis/Mega Drive comments
I'm not a game developer, I don't have the knowledge to do it, nor do I have the time to learn. But I'm an enthusiast of having games from one platform, ported to another.
The alternative here would be to not have Xevious on Mega Drive (or wait for someone that knows to do it). I choose the first.
AI is here to stay.
