AI Bot Plays Castlevania So You Don’t Have to

Posted on by

We’re not allowed to have TV here in the Hackaday Wonder Bunker, but occasionally we’ll pool together the bandwidth credits they pay us in and gather ’round the old 3.5 inch TFT LCD to watch whatever Netflix assures us is 93% to our liking. That’s how we found out they’ve made a show based on, of all things, one of the Castlevania games for the NES. We wanted to play the game to understand the backstory, but since it hails from the era of gaming where primitive graphics had to be supplemented with soul-crushing difficulty, we didn’t get very …read more

Wheel of Fortune Gets Infinite Puzzles on NES

Posted on by

Wheel of Fortune is a television game show, born in the distant year of 1975. Like many popular television properties of the era, it spawned a series of videogames on various platforms. Like many a hacker, [Chris] had been loading up the retro NES title on his Raspberry Pi when he realized that, due to the limitations of the cartridge format, he was playing the same puzzles over and over again. There was nothing for it, but to load a hex editor and get to work.

[Chris’s] initial investigation involved loading up the ROM in a hex editor and simply …read more

Metroid, Zelda, and Castelvania Auto-Mapped with NES Emulation & Heuristics

Posted on by

The NES was one of the flagship consoles of the glorious era that was the 1980s. Many of the most popular games on the platform involved some sort of adventure through scrolling screens — Metroid, Super Mario, and Zelda all used this common technique. For many games, keeping track of the map was a huge chore and meant mapping by hand on graph paper or using the screenshots published in Nintendo Power magazine. These day’s there’s a better way. [Daniel] set out to automatically map these huge two-dimensional worlds, developing software he calls WideNES to do it.

WideNES is an …read more

Find Your Level – Extracting NES Game Data Using Python

Posted on by

Just this summer, the Nintendo Entertainment System had its 35th release anniversary, and even after years of discontinuation, it is still going strong in the hacker community. Exhibit A: [Matthew Earl]. For one of his upcoming projects, [Matthew] needed to get his hands on the background images of the NES classic Super Mario Bros. Instead of just getting some ready-rendered images and stitching them together, he decided to take care of the rendering himself, once he extracts the raw game data.

Since there is no official source code available for Super Mario Bros, [Matthew] used a disassembled version to get …read more

A Lightgun For LCDs – Thanks To Maths!

Posted on by

Light guns were a fun way to learn to shoot things on consoles, enjoying their heyday in the 80s and 90s. The original designs largely relied on the unique characteristics of CRT televisions and the timing involved in the drawing of their frames. Unfortunately, due to a variety of reasons (dependent on the exact techniques used), they typically do not work at all with modern LCD & plasma screens.

Recently, there has emerged a new project called the Sinden Lightgun. In the How It Works video, it seems to use a fairly standard 30fps camera inside the gun to image …read more

Reverse-Emulating NES: Nintendception!

Posted on by

This is a stellar hack, folks. [Tom7] pulled off both full-motion video and running a Super Nintendo game on a regular old Nintendo with one very cute trick. And he gives his presentation of how he did it on the Nintendo itself — Nintendo Power(point)! The “whats” and the “hows” are explained over the course of two videos, also embedded below.

In the first, he shows it all off and gives you the overview. It’s as simple as this: Nintendo systems store 8×8 pixel blocks of graphics for games on their ROM cartridges, and the running program pulls these up …read more
