A while ago Displaced Gamers, as part of their great Behind The Code series, did a video about how awful NES Strider’s sprite updating was. Arcade Strider was huge hit and outright masterpiece, a great arcade platformer released right before fighting games took over game rooms around the world, but NES Strider was a wretched thing, full of big ideas but with code woefully unable to live up to them. Imagine a puppy trying to do your taxes. It might put up an adorable effort, but it’s just not going to get the job done.
We linked to their last video examining its malformed construction. Well, Strider is the well of crap that keeps on gushing, and so Displaced Gamers has another video on the subject of the flaws in its programming, this time about its player physics. Walking into walls causes Strider Hiryu to shudder in place; jumping beneath a low ceiling causes him to bump his head repeatedly as his jump continues even though there’s no room to ascent; and his infamous “triangle” wall jump is so wonky that it literally requires a frame-perfect input to pull off, and not even the right frame. You have to jump the frame before you contact the wall!
Here is the new video, which explicates the entire cruddy system. It goes into exquisite/excruciating detail, including tracing the code and examining Hiryu’s X and Y coordinates on a frame-by-frame basis. It’s the kind of deep geekery that I just know you love/hate! Enjoy/despair!
