Game Gear HDMI with SNES Controller

With its backlit color screen and Master System compatibility, the Game Gear was years ahead of its main competition. The major downside was that it tore through alkaline batteries quickly, and for that reason the cheaper but less equipped Game Boy was still able to compete. Since we live in the future, however, the Game Gear has received new life with many modifications that address its shortcomings, including this latest one that adds an HDMI output.

The core of the build is an FPGA which is used to handle pixel decoding and also handles the HDMI output. The FPGA allows for a speed high enough to handle all the data that is required, although [Stephen] still has to iron out some screen-filling issues, add sound over HDMI, and take care of a few various pixel glitches. To turn this hack into a complete hodgepodge of adapters, though, [Stephen] has also added an SNES controller adapter to the Game Gear as well. Nintendo has featured Sonic in many of its games, so although we may have disagreed back in the early 90s we think that this Sega/Nintendo pairing is not crossing any boundaries anymore.

Game Gears have had their share of other modifications as well to make them more capable as a handheld system than they were when they were new. We’ve also seen them turned into a console system (they were Master System compatible, after all) and converted into other things entirely, too.

Interfacing a Retro Controller using the USBASP

An ISP dongle is a very common piece of equipment on a maker’s bench. However, its potential as a hackable device is generally overlooked. The USBASP has an ATmeg8L at its heart and [Robson] decided that this humble USB device could be used as an interface between his PC and a SNES Joypad.

A SNES controller required three pins to communicate with a host: clock, data and latch. In his hack, [Robson]  connects the controller to the ISP interface using a small DIY adaptor and programs the AVR using the V-USB library. V-USB is a software USB library for small microcontrollers and comes in pretty handy in this instance.

[Robson] does a pretty good job of documenting the entire process of creating the interface which includes the USB HID code as well as the SNES joypad serial protocol. His hack works on both Windows and Linux alike and the code is available on GitHub for download.

Simple implementation like this project are a great starting point for anyone looking to dip their toes in the DIY USB device pool. Veterans may find a complete DIY joystick more up their alley and will be inspired by some plastic techniques as well.

Super Mario World Jailbreak Requires no External Hardware

[SethBling] has released a Super Mario World jailbreak that allows players to install a hex editor, then write, install and run their own game mods. What’s more is this all works on unmodified cartridges and SNES hardware. No hardware hacks required.

[Seth] is quick to say he didn’t do all this alone. This mod came to be thanks to help from [Cooper Harasyn] who discovered a save file corruption glitch, [MrCheese] who optimized the hex editor, and [p4plus2] who wrote some awesome mods.

While no soldering and programming of parts are required, installing this mod still requires quite a bit of hardware. Beyond the SNES and cartridge, you’ll need two multitaps, three controllers, and clamps to hold down buttons on the controllers. Even then the procedure will take about an hour of delicate on-screen gymnastics. Once the jailbreak is installed though, it is kept in savegame C, so you only have to do it once.

What does a hex editor allow you to do? Anything you want. Mario’s powerup state can be edited, one memory location can be modified to complete a level anytime you would like. It’s not just modifying memory locations though – you can write code that runs, such as [p4plus2’s] sweet telekinesis mod that allows Mario to grab and move around any enemy on the screen.

It’s always awesome to see old video game hardware being hacked on by a new generation of hackers. We’ve seen similar work done on Super Mario Brothers 3, and an original GameBoy used to pilot a drone, just to name a couple.

Smartphone Case For The Retro Gamer

A well-designed phone case will protect your phone from everyday bumps with only as much style flair as you’d like. While protection is usually the only real function of a case, some designs — like [Gabbelago]’s Emucase — add specific utility that you might not have known you needed.

Contrary to most cases, the Emucase fits over your phone’s screen, and the resulting facelift emulates the appearance of a Game Boy for easier — you guessed it — Game Boy emulation play on your smartphone.

Cannibalizing a USB SNES gamepad for its buttons and rubber contact pads, Gabbelago then threaded some wire through the contacts, securing it with copper tape and glue; this provides a measurable level of capacitance to register on the touchscreen. Using heat to bend the sides of the 3D printed case so it can attach to the phone is probably the trickiest part of this cool project. Check out his build instructions for any pointers you need.

Learn Some Plastic Techniques With This SNES WiiMote Mod

Not all hacks have to be deeply technical. Sometimes a good show of skill is just as impressive. [lyberty5] takes two completely different hunks of plastic and somehow epoxies them into a convincing and, most impressively, reliable chimera.

While the WiiMote’s motion controls certainly caused a lot of wordy debate on the Internet when it was debuted. While everyone and their grandmother who owned a game company rushed out to copy and out-innovate it once they saw Nintendo’s hoard of dragon gold. Most game designers had other thoughts about the concept, mostly that it wouldn’t do for a platformer. So the gamer caught in the middle of it all had to rotate their grip-optimized rectangle 90 degrees and blister their thumbs on tiny buttons to play.

SNES EPROM Programmer with Arduino

Most video game manufacturers aren’t too keen on homebrew games, or people trying to get more utility out of a video game system than it was designed to have. While some effort is made to keep people from slapping a modchip on an Xbox or from running an emulator for a Playstation, it’s almost completely impossible to stop some of the hardware hacking that is common on older cartridge-based games. The only limit is usually the cost of an EPROM programmer, but [Robson] has that covered now with his Arduino-based SNES EPROM programmer.

Normally this type of hack involves finding any cartridge for the SNES at the lowest possible value, burning an EPROM with the game that you really want, and then swapping the new programmed memory with the one in the worthless cartridge. Even though most programmers are pricey, it’s actually not that difficult to write bits to this type of memory. [Robson] runs us through all of the steps to get an Arduino set up to program these types of memory, and then puts it all together into a Super Nintendo where it looks exactly like the real thing.

If you don’t have an SNES lying around, it’s possible to perform a similar end-around on a Sega Genesis as well. And, if you’re more youthful than those of us that grew up in the 16-bit era, there’s a pretty decent homebrew community that has sprung up around the Nintendo DS and 3DS, too.

SNES Micro Is A Pi Z Of Art

Clay is a shapeless raw material that’s waiting to be turned into awesomeness by your creativity. So is the Raspberry Pi. [Dorison Hugo] brought the two together in his artfully crafted SNES micro – a tiny retro gaming console sculpted from clay.
