Pi Handheld With a Mindblowing Enclosure

The Raspberry Pi is possibly the world’s most popular emulation platform these days. While it was never intended to serve this purpose, the fact remains that a small, compact computer with flexible I/O is ideally suited to it. We’ve featured a multitude of builds over the years using a Pi in a mobile form factor to take games on the go. [Michael]’s build, however, offers a lot more than a few Nintendo ROMs and some buttons from eBay. It’s a tour de force in enclosure design.

The build starts with the electronics. In 2017 it’s no longer necessary to cobble …read more

Emulate ICs in Python

Most people who want to simulate logic ICs will use Verilog, VHDL, or System Verilog. Not [hsoft]. He wanted to use Python, and wrote a simple Python framework for doing just that. You can find the code on GitHub, and there is an ASCII video that won’t embed here at Hackaday, but which you can view at ASCIInema.

Below the break we have an example of “constructing” a circuit in Python using ICemu:

dec = SN74HC138() sr1 = CD74AC164() sr2 = CD74AC164() mcu_pin = OutputPin('PB4') sr1.pin_CP.wire_to(dec.pin_Y0) sr2.pin_CP.wire_to(dec.pin_Y1) sr1.pin_DS1.wire_to(mcu_pin) sr2.pin_DS1.wire_to(mcu_pin) print(dec.asciiart()) _______ A>|- U +|>Y7 B>|- +|>Y6 C>|- +|>Y5 G2A>|- +|>Y4

Discontinued Nintendo Consoles and Raspberry Pis

Nintendo has discontinued a Classic gaming console. It’s a pity, yes, but with the release of Nintendo’s new gaming console, they probably have bigger fish to fry. That doesn’t mean these discontinued Nintendo consoles will die a slow, miserable death locked away in a closet; at least one of them will live on with the heart of a Raspberry Pi.

This is a project [Liam] has been working on since 2012, just after he got the first edition of the Raspberry Pi. While some people were figuring out how to stuff the Pi inside a Nintendo Entertainment System or a …read more

Raspberry Pi-Based Game Boy Emulator

The most popular use for a Raspberry Pi, by far, is video game emulation. We see this in many, many forms from 3D printed Raspberry Pi cases resembling the original Nintendo Entertainment System to 3D printed Raspberry Pi cases resembling Super Nintendos. There’s a lot of variety out there for Raspberry Pi emulation, but [moosepr] is taking it to the next level. He’s building the smallest Pi emulation build we’ve ever seen.

This build is based on the Pi Zero and a 2.2″ (0.56 dm) ili9341 TFT display. This display has a resolution of 240×320 pixels, which is close enough …read more

ENIAC: The Way We Were

When I first got interested in computers, it was all but impossible for an individual to own a computer outright. Even a “small” machine cost a fortune not to mention requiring specialized power, cooling, and maintenance. Then there started to be some rumblings of home computers (like the Mark 8 we recently saw a replica of) and the Altair 8800 burst on the scene. By today’s standards, these are hardly computers. Even an 8-bit Arduino can outperform these old machines.

As much disparity as there is between an Altair 8800 and a modern personal computer, looking even further back is …read more

Fixing Bugs In A 37 Year Old Apple II Game

Emulators are a great way to reminisce about games and software from yesteryear. [Jorj Bauer] found himself doing just that back in 2002, when they decided to boot up Three Mile Island for the Apple II. It played well enough, but for some reason, crashed instantly if you happened to press the ‘7’ key. This was a problem — the game takes hours to play, and ‘7’ is the key for saving and restoring your progress. In 2002, [Jorj] was content to put up with this. But finally, enough was enough – [Jorj] set out to fix the bug in …read more

Shmoocon 2017: On Not Reverse Engineering Through Emulation

Right now, I’m at Shmoocon, and it’s living up to all expectations. That’s a tall order — last year, the breakout talk was from [Travis Goodspeed] on his efforts to reverse engineer the firmware for a cheap Chinese radio. Four people in the room for that talk last year bought the radio on Amazon, and now there’s a legitimate open source project dedicated to building firmware and tools to support this radio.

Now that [Travis] has a few compatriots working on firmware for this radio, he has the same challenges as any other team. The project needs unit tests, and …read more

Anti-Emulation Tricks on GBA-Ported NES Games

Emulation is a difficult thing to do, particularly when you’re trying to emulate a complex platform like a game console, with little to no public documentation available. Often, you’ll have to figure things out by brute force and dumb luck, and from time to time everything will come unstuck when a random piece of software throws up an edge case that brings everything screeching to a halt.

The Classic NES series was a handful of Nintendo Entertainment System games ported to the Game Boy Advance in the early 2000s. What makes them unique is a series of deliberately obtuse programming …read more
