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

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

DEF CON 2018: Hacking Medical Protocols to Change Vital Signs

LAS VEGAS – In recent years there has been more attention paid to the security of medical devices; however, there has been little security research done on the unique protocols used by these devices. Many of the insulin pumps, heart monitors and other … Continue reading DEF CON 2018: Hacking Medical Protocols to Change Vital Signs

VCF East: The Desktop ENIAC

The ENIAC, or Electronic Numerical Integrator and Computer, is essentially the Great Great Grandfather of whatever device you’re currently reading these words on. Developed during World War II for what would be about $7 million USD today, it was designed to calculate artillery firing tables. Once word got out about its capabilities, it was also put to work on such heady tasks as assisting with John von Neumann’s research into the hydrogen bomb. The success of ENIAC lead directly into the development of EDVAC, which adopted some of the now standard computing concepts such as binary arithmetic and the idea …read more

Commodore 64 to Raspberry Pi Conversion is Respectful & Complete

We’re big fans of taking old computers and giving them a new lease on life, but only when it is done respectfully. That means no cutting, no hot glue, and no gouging out bits to make the new computer fit. It’s best if it can be done in a way that the original parts can be restored if required.

This Commodore 64 to Raspberry Pi conversion from [Mattsoft] definitely fits our criteria here, as it uses the old keyboard, joystick connectors and output portholes for the required authentic look. It does this through the clever use of a couple of …read more

A Laser Cut Arcade Cabinet for Ants

Most of us would probably like to have an arcade cabinet at home, but it’s hard to justify the space they take up. Sure it’s an awesome conversation starter when friends are over, and you might even play it regularly, but at some point you’ll look over at the corner and realize there’s probably something more practical you could be doing with that particular section of the room.

Perhaps the solution is to just make a smaller one. You could do one at half scale, or even desktop sized. But why stop there? Why not make one so small that …read more

Emulating A Forgotten UNIX Box

The AT&T 3B2 series of computers are historically significant, being the main porting platform for System V Release 3 UNIX. Unfortunately, the documentation for these computers has been nearly lost to the sands of time. They are, however, architecturally interesting machines, and [Seth Morabito] has been working for some time on reverse engineering them. Now, [Seth] is calling it: his AT&T 3B2/400 emulator is almost complete, resurrecting an ancient machine from the dead by studying UNIX source code.

The architecture of this computer is unlike anything you’ve seen before, but well-suited to a UNIX machine. The chipset is built around …read more
