Crack Mike Tyson’s Punch Out Bang Bang Passwords

[Bisqwit] has feelings about games that use exclamation points in his idiosyncratic walkthrough of all the nuances of the passwords in the famous Punch Out Bang Bang.

As he states in his deeply weird (though in no way wrong) channel intro, when he’s not driving a bus or teaching Israeli dance, he works hard to understand the things around him. Naturally, a mysterious phone number shaped set of digits in a favorite game was a secret worth extracting.

The digits can represent every possible state in the game.  It uses a pretty simple decoding and encoding scheme, which he walks through. As he says, it all becomes clear when you can see the source code.

After working through all the quirks he is able to arbitrarily generate any state in the game and handle the exceptions (such as Nintendo USA’s phone number). You can see all his code here and try it out for yourself. Video after the break.

We’ve grown to respect [Bisqwit] as the explainer of all things console games. You will like his explanation of how to write a code emulator for an NES CPU.

BASIC Interpreter Hidden in ESP32 Silicon

We’ve been keeping up with the ongoing software developed for the ESP32 WiFi chip, and that means a lot of flashing, hooking up random wires, and rebooting. Along the way, we stumbled on an Easter egg: the ESP32 processor has a built-in BASIC interpreter to fall back on.

That’s a cool little hack to find, but we couldn’t find some crucial functions that would have made it a lot more useful. Still, it’s great fun to play around in real-time with the chip. And you’ll absolutely get an LED blinking faster in ESP32 BASIC than you will on an Arduino!

Smallest BASIC Computer?

This may be the most minimal computer that we’ve ever seen running BASIC. Hackaday.io user [Kodera2t] has been working through the history of computing, so after his 4-bit CPU, he stepped up his game to eight bits. It’s amazing how much can be done with so little. It’s basically a Z80 on a single PCB.

[Kodera2t] is careful to give credit where credit is due: the design of this computer is by [Grant Searle]. It’s amazing what you can do with an old CPU (6809), some SRAM, a controller-interface chip, and an EPROM for your BASIC. Check out the GitHub for the computer’s PCB files if you want to make your own — it’s a very hobbyist-friendly two-layer board with fat traces. Or you could put it all together on a breadboard. It’s that non-critical.

The other sweet touch is this monochrome CRT build that pairs up with the tiny computer.

[Kodera2t] is doing some really clever retro and minimalistic hacks, and putting them all up on Hackaday.io. You should really give his whole portfolio a look. We recently wrote up his experimentations with the Atmel ATtiny10 if you’re in the mood for something more modern.

A DOS Education in Your Browser

In the 1970s and 1980s, a lot of us learned to program using good old-fashioned BASIC on machines ranging from Altairs, Commodores, Apple IIs, and the like. Sometime in the 80’s the IBM PC running MSDOS because the de facto standard, but it was still easy enough to launch BASIC and write a simple little program. Of course, there were other programs, some serious like C compilers, some semi-serious like flight simulators, and some pure fun like Wolfenstein 3D.

If you read Hackaday, you’ve probably noticed that a lot of people emulate old computers–including old MSDOS PCs–using a variety of techniques, including Raspberry PI boards running DOSBox or another emulator. Honestly, though, that’s a lot of effort just to run some old software, right? You can load up DOS emulators on your desktop too. That’s a little easier, but you still have to find software. But if you are as lazy as we are, you might want to check out the MSDOS collection at archive.org.

Basically, Its Minecraft

[SethBling] really likes Minecraft. How can you tell? A quick look at his YouTube channel should convince you, especially the one where he built a full-blown BASIC interpreter in Minecraft. It is not going to win any speed races, as you might expect, but it does work.

For novelty and wow factor, this is amazing. As a practical matter, it is hard to imagine the real value since there are plenty of ways a new programmer could get access to BASIC. Still, you have to admire the sheer audacity of making the attempt. One Hackaday poster (who shall remain nameless) once won a case of beer by betting someone he or she could write a BASIC compiler in BASIC, so we aren’t sticklers for practicality.

ESP8266 BASIC WiFi Thermostat is Child’s Play

If you’ve read any of our posts in the last couple years, you’ll have noted that our community is stoked about bringing the Internet to their devices on the cheap with the ESP8266 modules. Why? This forum post that details making a WiFi thermostat really brings the point home: it’s so easy and cheap to build Internet-enabled devices that you almost can’t resist.

When the ESP8266 first came out, there very little documentation, much less code support. Since then Espressif’s SDK has improved, the NodeMCU project brought Lua support, and there’s even Arduino support. Most recently, BASIC has been added to the ESP stable, and that really lowers the barriers to creating a simple WiFi widget, like the thermostat example here that uses a Dallas DS18B20 temperature sensor and an LED as a stand-in for the heater element.

The hardware for this project, a re-build of this demo code from the ESP8266 BASIC docs, is nothing more than a few off-the-shelf parts soldered together. No schematic required.

What makes the project work behind the scenes is some clever code-reuse by [Rotohammer] on the ESP8266 forums. Essentially, he wrapped the Arduino’s one-wire library, giving it simple BASIC bindings. Then all that’s left for the BASIC coder is to read the value and print it out to a webpage.

There’s all sorts of details swept under the rug here, and those of you out there who are used to bare-metal programming will surely huff and puff. But there’s a time for building your own injection-molder to make DIY Lego bricks, and there’s a time to just put blocks together. This project, and the BASIC interpreter that made it possible, demonstrate how much joy someone can get from just putting the parts together.

Basically, It’s an ESP8266

Before the Arduino, there was the Parallax Basic Stamp. It was an easy-to-use PIC chip on a PCB that you programmed in BASIC — a story of those humble beginnings was published earlier this week. Before that, even, legions of small computers from TRS-80s to Commodore 64s and even Altairs were commanded primarily by the BASIC language. BASIC was easy to run on a small machine and very simple to learn. Old fashioned BASICs are difficult to use to write huge systems, but a lot of small computers aren’t going to run very large programs anyway.

The ESP8266 is more than a just a WiFi peripheral for a microcontroller. It is its own little computer in its own right. While it is common to run the “AT” firmware, Lua, or program the device yourself, you can now load the beast with a version of BASIC.
