Can we run Ghosts ‘n Goblins on the NES at 60 fps? Yes! …Kinda? It’s complicated. Micronics was responsible for developing several games on the NES, and their results were a bit messy at times. Let’s dive into what Micronics did to update NES graphics between video output frames and also figure out why the […]
The controls in Ikari Warriors for NES are sluggish to say the least. It seems like it takes forever just to turn in the direction you want to go. This is quite different from the overhead levels of Super C where you snap to face the direction that was just pressed. The arcade version of […]
Why does Contra Force on the NES slow down so often? It seems to me that Konami developed this game for a superior mapper chip like the VRC6, planned to release it as “Arc Hound” in Japan in 1991, missed their intended release date, decided to shift most development to the Super Famicom, and basically […]
In a previous episode of Behind the Code, we talked about how the scoring logic of Tetris can crash the game at high levels. Now what is even more interesting is that you can hook up extra controllers to the expansion port on a Famicom and use them to redirect code execution to the A-Type […]
This has been a really big year so far for Tetris on the NES. Players have found ways to provide controller inputs at speeds the programmers of the game didn’t anticipate. A technique called “rolling” has allowed players to move pieces at such fast speeds that they can progress beyond level 150! Unfortunately, this might […]
While I was working on the previous episode of Behind the Code and researching Jekyll’s walking speed in Dr. Jekyll and Mr. Hyde for the NES, I noticed that the frame rate was rather odd. Turns out it is REALLY odd. If you’ve played the game, you may have noticed that the speed is inconsistent. […]
A friend of mine rented Dr. Jekyll and Mr. Hyde when it was new, and we gave it a try. It was certainly different than any of the other games we had played on the NES. Try playing Contra or Punch-Out and then switching over to a game that demands patience like this one does. […]
Have you ever played The Terminator for the NES? Landing is difficult. Jumping is inconsistent. Sometimes you appear to land but fall through the ground! Sometimes you fall off the edge of a platform while running even though you swear you pressed jump before you got there. Sometimes jumping to the first ledge works but […]
NES Strider feels janky. We’ve known that since it was released. But how bad could it be? … Oh! Absolutely terrible! Jumping, running into a wall, and falling – simple things in any other game seem to be half-baked in Strider. The physics are worse than you could possibly imagine. Why do you slam your […]
Punch-Out!! has been on my list of games to investigate for a long time, and I finally have something to show after a crazy amount of research. This video covers how opponent data is used to determine where to branch and what to do in code, how to manipulate boxer behavior, secrets that you will […]
