I've already done some mouthing off about how much I love Cave Story, the one-man miracle game that looks great, sounds great and plays better.
Not surprisingly, Cave Story has a significant fandom. In fact, a member at the Way of the Pixel forums recently posted a relevant challenge: whip up "screenshots" of what Cave Story might look like if it were ported to less-powerful systems.
The results are amusing, especially the Spectrum ZX mock-up. I'd like to see something done in the style of the Apple ][ or better yet, the Commodore 64.
There's also a screenshot guessing at what Cave Story might look like on the Master System. The forum member went by the system's specs and got something pretty close to the original game. I wonder how well Cave Story would have worked on the NES? The graphics would probably port over well, but the screen tends to get pretty busy sometimes.
I eagerly await the Nintendo DS fan-port.
