The art and engineering of Sega CD Silpheed

The Sega CD is my favorite console and I was fortunate enough to have one growing up. Silpheed was unlike anything else. Unlike most FMV games, Silpheed actually felt like controlling a movie. During the first level when laser blasts are tearing through the fleet gigantic ships filling the screen with debris, I could barely believe what I was seeing.

As the article points out, while it is an FMV game, it tries to fool you into thinking it’s a polygon based game. The Sega CD had no 3D capabilities at all (just 2D rotation and scale). But GameArts pulls off the FMV so convincingly, down to the aliasing, that it’s hard to understand (at least to my 12-year old self) how it could be anything other than 3D rendering.

It’s often panned as not the best shooter, but the gameplay was secondary to the experience. I don’t know how it would play for someone who didn’t experience it at the time, but it will always be one of my favorites on the system.

If you've never seen Overdrive 2 by Titan (a demo scene group), it's unbelievable what the MegaDrive can do stock.

I'm reasonably familiar with the hardware, I've written some games from scratch and I still have absolutely no idea how they did most of it.

This was submitted by a bot :D I subscribe to Fabien's RSS and he must have changed something in the server because I got this post on my RSS reader (again, as it's an old post), and here it is submitted to HN (again)

I think the article is sorta wrong about the sound setup, the Mega Drive I does have a sound input on the expansion port, and mixes it into its sound output. Otherwise stuff like RF cables wouldn't get Mega CD based audio (and you can do silly stuff like a Mega Drive II, which doesn't have a headphone port, with a Mega CD I).

I was going to say the patch cable setup was just a passive aid to take the Mega Drive I's minijack stereo output (the big DIN AV connector on the rear only does mono) to a more serious two RCA jack setup. But looking at a schematic to check, it does do more stuff, and apparently connecting the patch cable will reroute stuff so the sound mixing is done on the Mega CD side, not the Mega Drive side (early Mega Drive revisions are somewhat infamous for showing that Sega hadn’t quite mastered the dark arts of analogue sound circuitry).

(I would double check some of this, but my Mega Drive / Mega CD setup isn't to hand, and the CD drive is broken anyway, although I understand the JP/PAL piano tune on the logo screen is all from the Mega CD side?).

Cool article, but Silpheed is a genuinely awful game. Just warning if you are tempted to play it after this lol

How they fit the Sonic 3D intro onto a sega mega drive _cartridge_!

> That was a departure from how I normally work since I did not write a single line of code. I will likely write something about my A.I framework (and opensource it) next month.

If the author is around, super curious how they got to enjoy their workflow here in a side project, working with AI. This kind of situation, to me, is often where the joy is gone.

Using the ASIC meant for bitmap rotation and font rendering in an almost MPEG like fashion. Super clever.
