Golden Axe is great, and the Sonic 3/Sonic and Knuckles combo is one of the highest works of art from the 16-bit era, but for those of us without a working Genesis or Megadrive, we’ve had to make due with the ROMs others provide. [Lee] figured out an easy way to read the data off these old Sega cartridges using easily scavenged parts and an Arduino Mega, paving the way for an Arduino-based ROM dumper.
The connector on the bottom of a Sega Genesis cartridge has a 2×32 pinout, normally requiring 64 connections to actually read the card. These connectors aren’t readily available, but [Lee] did manage to find a few 2×31 pin connectors lying around in the form of old ISA sockets. The outer pins of a Genesis cart are used for grounds and a ‘cartridge insert’ slot, and after filing away the end of an old ISA connector, [Lee] found he could actually read the data on these old game cartridges.
There are 49 data and address pins on these old Sega carts, so an Arduino Mega needed to be brought into the mix to actually read some of the data on the ROM chip. As of now, [Lee] can read data from the cart but has only gotten so far as to read the licensing data stored at 0x80. Still, very cool and the first step towards an Arduinofied Sega cart dumper.
We really love when friendly competition leads to excellent hacking. Not too long ago, we showed you a nicely done Sega Genesis portable put together by console hacker [Downing] who challenged fellow hacker [EVIL NOD] to a build off. The two were hacking Sega consoles, [Downing’s] for personal use, while [EVIL NOD] was working on a commissioned build.
As you might have guessed, [Downing] finished first, but that doesn’t mean [EVIL NOD’s] console is anything but spectacular. His Sega Multi Gen is a portable Genesis console modified to play both NTSC and PAL games. It features a large 5” PSOne screen as well as the guts from an official 6-button Genesis game pad. The case was vacuum formed by [Downing], and is another example of his fine workmanship. The console looks as if it’s had the controller melted right into its face – a design that is sure to give you the authentic feel of sitting in front of your TV mashing away at the buttons.
Check out the video below to see an unboxing video that [EVIL NOD] put together before sending the console out to its new owner.

There’s something about portable gaming systems that just doesn’t get old. Perhaps its the nostalgia, or the unique cases and form factors the modders come up with. Whatever it might be, we think they’re great.
[Downing] wrote in to share a portable system he just wrapped up, called the GeneBoy. He broke down a Sega Genesis console to the bare necessities, then attached a 3.5” backup camera screen to serve as the display. A 3rd party Genesis controller donated its buttons to the GeneBoy, while his D-Pad was salvaged from an original Playstation controller.
The case was built from vacuum formed plastic, which made it easy to get just the size and shape he needed to hold everything together perfectly. Even though he says that the outside of the case got a bit roughed up during final assembly, we think it looks great. I would certainly enjoy having all the fun of [Sonic the Hedgehog] or Road Rash in the palm of my hand any day!
Continue reading to see the GeneBoy in action, and be sure to check out [Downing’s] blog along with the Modded by Bacteria forum thread where he discusses the finer details of its assembly.

If you’ve never been to a chiptune show – yes, they exist – you’ve noticed the awesome visuals behind the performers that are usually displayed with a glitching NES. If it’s a really good show, that 8-bit visualization will be in sync with the music and may actually serve as a lo-fi spectrum analyzer. [Andy] came up with his own visualization system for a Sega Genesis or Megadrive. With 16 bits behind his build, we’ll say if far surpasses the lowly NES.
For his visualization, [Andy] feeds audio into an ATMega328 and the ever-popular MSGEQ7 seven-band graphic equalizer IC. The output from the EQ goes straight to the second controller input of a Sega Nomad [Andy] had lying around that is running a custom ROM for his show. The ROM is programmed in tandem with the microcontroller project to serve as a spectrum analyzer for his shows.
You can check out [Andy]’s visualization with the chiptunes of Danimal Cannon after the break. We would prefer a demo featuring An0vA and the code for the microcontroller, but it’s still a very nice demo indeed.

[Bruno]’s Wii RetroPad Adapter was sent into the tip line, and we’re loving the possibility of using Playstation 2, Genesis, NES and SNES controllers with our Wii.
While there are commercial solutions that connect an NES or SNES controller to a Wii, everything connects to the GameCube port and there is no adapter for Sega or Playstation controllers. For his build, [Bruno] used an ATmega168 to read data from the classic controllers and translate that to the Wiimote I2C bus. Think of it as a new classic controller with the same form factor your 8-year-old self knew and loved.
The schematic for the build is very simple and [Bruno] has all the software out in the open. Even the PCB is single sided and looks like it would be a great candidate for a homebrew PCB. There’s no indication [Bruno] is trying to monetize his creation, so he’s either doing right, or so very wrong. Check out the Dualshock 2/Mario 3 demo of this board after the break.

We’ve been watching the development of the snega2usb since it’s debut on Hackaday. Now it’s grown up and is ready to be manufactured. In the low quality video above [Matthias] shows some of the latest high quality additions to the board. It now has a case, shiny new firmware, production made PCB, and game pad ports. The snega2usb is shipping this December for those who preorder now.
When we first posted [Matthias_H]’s USB reader for SNES game carts, it was met with enthusiasm. The snega2usb allows you to play SNES and Sega games on your pc right off the cartridge. The latest revision is even more amazing than the first. [Matthias] has added the ability to read Sega Genesis/Mega Drive cartridges as well as the ability to save games directly to the cartridge. The board has also been updated from the rats nest it used to be to a smart looking dual sided PCB. So far [Matthias] hasn’t had any trouble reading cartridges, even ones with the SuperFX chips. [Matthias] also launched a site for the project where the lastest information on its development can be found. [Matthias] is getting close to a production version which will feature better firmware, console quality connectors and a shiny case.
