NHL ’24 ROM Hack Reimagines Classic Game, Zamboni And All

Thirty years is a long time to keep a piece of software alive, but there aren’t many pieces of software like NHL ’94 for the Sega Genesis. Despite new annual iterations of publisher Electronic Arts’ NHL hockey video game some players never connected with it like quite like they did in 1994. For years now it’s been a tradition for members of the NHL ’94 forums to incorporate the hockey league’s current players into the Sega Genesis original, however, the work [Adam] contributed this season goes beyond a mere roster update. This NHL ’24 ROM hack is more like a complete overhaul. Everything that was old is new again. Continue reading NHL ’24 ROM Hack Reimagines Classic Game, Zamboni And All”

Mortal Kombat ROM Hack Kontinues Arcade Legacy

September 13th 1993, colloquially known as Mortal Monday, became as dividing line in the battle for 16-bit supremacy. The mega popular arcade game Mortal Kombat was ported to Super Nintendo and Sega Genesis consoles, and every fanboy and fangirl had an opinion on which version truly brought the hits. The Super Nintendo version opted to remove the blood and gore in an attempt to preserve the company’s family-friendly image. While the Sega Genesis merely locked the game’s more violent content behind a cheat code that so many fans learned by heart, ABACABB. Nintendo’s decision to censor Mortal Kombat on their console pushed public opinion in favor of the Sega Genesis version being superior, though it was clear that corners were cut in order to squeeze it onto a cartridge. Recently a group of developers led by [Paulo] sought to restore the Genesis version to its full potential with a ROM hack they’re calling Mortal Kombat Arcade Edition.

Mortal Kombat Arcade Edition is the sort of ROM hack where every facet of the game has been retouched. All sorts of sound effects and animations that were omitted in the 1993 translation to the Genesis have now been restored in higher quality. Every fighter’s look was remastered to more closely match the arcade presentation complete with move timing tweaks. Secret characters like Reptile, Noob Saibot, and Ermac are all playable, plus all the character bios from the arcade game’s attract mode make an appearance. An SRAM save feature was implemented in order to save high scores, and for an additional dose of authenticity there’s even a “DIP switch” configuration screen where you can set it to free play.

This ROM hack comes as an IPS patch that can be applied to a legitimate dump of the user’s Sega Genesis or Mega Drive cartridge. The site hosting the Mortal Kombat Arcade Edition patch features an online IPS patching tool called Rom Patcher JS that makes the patching process more convenient for those attached to their browser. The patched ROM can then be enjoyed in the user’s favorite emulator of choice, though running it on original hardware via a ROM cart is also possible (even encouraged). Considering the limitations of the Sega Genesis’ color palette the revamped look of Mortal Kombat Arcade Edition is all the more impressive. It just goes to show you that Genesis still does!

An Open Hardware Sega Genesis Cartridge Dumper

You might be wondering why anyone would build device to dump Sega Genesis and Mega Drive cartridges. Perhaps they want to play their well-worn copy of The Lost Vikings on their phone, or they want to keep their QVC Limited Edition Maximum Carnage box set in near mint condition. Maybe. But we’re betting that [tonyp7] was just looking for a challenge, and as an added bonus, the world gets another cool open hardware gadget in the process. Sounds like a good deal to us.

Based on the ATmega324PB, the GenDumper can take those dusty old Sega cartridges and back them up to an image file on your computer. Right now the hardware depends on a Windows program, but according to the documentation, [tonyp7] is working on a platform-agnostic Python script so everyone can play along. What you do with the image file after you’ve dumped it is your business, but presumably loading it up in an emulator would be the next step.

Considering how easy it is to find ROMs for these old games online, do you actually need a GenDumper of your own? Probably not. But it’s still an interesting piece of hardware, and if you look close enough, you just might learn a thing or two from the design. For example, [tonyp7] shows how a relatively easy to work with 12 pin USB-C connector can be used on your USB 2.0 projects to embrace the new physical connector without diving into a full USB 3.0 implementation. The keen-eyed reader might also note there’s a lesson to be learned about finalizing the name of your project before sending off your PCBs for manufacturing.

A perusal of the archive uncovered a similar project from 2012 that, believe it or not, was also tested on a copy of Madden 96. Whether that means the game is so beloved that hackers want to make sure its preserved for future generations, or so despised that they are secretly hoping the magic smoke leaks out during testing, we can’t say.

Thea Flowers – Creating A Sega-Inspired Hardware Synthesizer From The Ground Up

For those who grew up with video games, the legendary sounds of consoles past are an instant nostalgia hit. [Thea Flowers] first got her hands on a gamepad playing Sonic the Hedgehog, so the sounds of the Sega Genesis hold a special place in her heart. Decades later, this inspired the creation of Genesynth, a hardware synth inspired by the classic console. The journey of developing this hardware formed the basis of [Thea]’s enlightening Supercon talk.

[Thea’s] first begins by exploring why the Genesis sound is so unique. The Sega console slotted neatly into a time period where the company sought to do something more than simple subtractive synthesis, but before it was possible to use full-waveform audio at an affordable price point. In collaboration with Yamaha, the YM2612 FM synthesis chip was built, a cost-reduced sound engine similar to that in the famous DX7 synthesizer of the 1980s. This gave the Genesis abilities far beyond the basic bleeps and bloops of other consoles at the time, and [Thea] decided it simply had to be built into a dedicated hardware synth.

MDFourier Project Seeks The Genesis Of SEGA 16-bit Sound

It always sounded a bit crunchy, but crunchy in a good way. SEGA’s 16-bit console, whether you call it the Genesis or Mega Drive, always had a unique sound thanks to it’s Yamaha YM2612 sound chip. The chip’s ability to reproduce shredding guitars and blasting bass drums was a joy to hear when placed in the hands of capable game developers. Games such as Toe Jam & Earl, Streets of Rage 2, and Sonic the Hedgehog 3 provided some of the most incredible game soundtracks of the ’90s; and while the retail shelf life of those games may have passed, their influence on sound design should not. One individual that is seeking to preserve that quintessential SEGA sound is [Artemio] whose MDFourier project seeks to capture it for future generations to hear.

MDFourier is a crowd sourced project. Users are asked to use two pieces of software to first generate common audio through a videogame console, and another to analyze the output as to form an audio signature of that machine. Of course SEGA were not always known for their stellar manufacturing record. Throughout the dozen or so board revisions of the Model 1 console there were factory bodge wires, there was also the Model 2 console, Model 3 console, Nomad handheld, Mega Jet, CDX/Multi-Mega, and Wondermega karaoke machine. Each new revision of machine created a slightly new soundscape, and no single piece of emulation software takes them all into account. [Artemio] wants to aggregate all of this data in order to improve SEGA Genesis/Mega Drive emulators, FPGA implementations, or whatever else the future may hold.

Fans of the suite of SEGA consoles, or even fans of great documentation, can take a look at some of initial results as well as the written procedure for contributing to the MDFourier project. For those seeking a more visual step-by-step approach there is this video from YouTube channel RetroRGB below: If you’d like that Sega sound for your MIDI instrument, take a look at this MIDI synth using a Genesis sound chip.

Full Motion Video And 3D Graphics Make This Genesis Demo Pop

The SEGA Genesis (aka Mega Drive) was launched at the tail end of the 1980s, bringing a new level of performance to the console world. At the time, 2D graphics ruled the roost, outside a few niche titles here and there. Decades later however, the demoscene continues to work in earnest. The Red Eyes demo is a great example of what can be done when pushing the Genesis hardware to the limits.

The demo features full motion video and an impressive 3D sequence. It’s quite a feat to pull this off with the limited resources of the Genesis platform. [Remute], [Kabuto] and [Exocet] have laid their secrets bare in a technical document, describing in explicit detail how it’s all achieved.

There’s plenty of juicy reading material here. There are palette hacks to produce high-quality greyscale images, rendering tips to produce the smooth 3D rendered sequences, as well as optimizations to create the best possible sample playback using the onboard YM2612 sound chip. It’s a tour de force of development, and it’s astounding to look behind the curtain to see just what can be achieved.

If you’re thinking about tinkering with the Genesis yourself, you might find it useful to have a dev kit on your bench. Video after the break.

How To Interface Sega Controllers, And Make Them Wireless

The Sega Genesis, or Mega Drive as it was known outside North America, was a popular console for the simple fact that Sega did what Nintendidn’t. Anachronistic marketing jokes aside, it brought fast scrolling 16-bit games to a home console platform and won many fans over the years. You may find yourself wanting to interface with the old controller hardware, and in that case, [Jon Thysell] is here to help.

[Jon] has done the work required to understand the Sega controller interface, and has shared his work on Github. The interface is an interesting one, and varies depending on the exact console and controller hardware used. The original Master System, with its D-pad and two buttons, simply uses six pins for the six switches on the controller. The 3-button Genesis pad gets a little more advanced, before things get further complicated with the state-machine-esque 6-button pad setup.

[Jon] helpfully breaks down the various interfaces, and makes it possible to interface them with Arduinos relatively easily. Sharing such work allows others to stand on the shoulders of giants and build their own projects. This nets us work such as [Danilo]’s wireless Genesis controller build. By combining the knowledge of the Sega protocol with a few off-the-shelf Arduinos and Bluetooth parts, it makes whipping up a wireless controller easy.

In this day and age, most console controllers can be readily interfaced with a PC with a variety of simple solutions – usually USB. You might feel like trying something harder though, for instance interfacing modern Nintendo controllers to a C64. Video after the break.
