Retro City Rampage's Creator Set To Release 'Grandtheftendo' Prototype Nintendo NES ROM

Retro-City-Rampages-Creator-Set-To-Release-Grandtheftendo-Prototype-Nintendo-NES-ROMThe recently released Retro City Rampage is nothing short of retro gaming nostalgia at its best. With development of the heavily influenced 8-bit title original starting out on the NES, it comes as no surpirse that the game's creator is set to pay further homage to the 8-bit era by including a playable version of the Grandtheftendo prototype in the Steam & WiiWare versions.

The original Nintendo NES version of Retro City Rampage, also known as Grandtheftendo, was an ambitious homebrew effort by the game's creator, Brian Provinciano. Despite many promising screenshots reaching the masses and an overwhelming response, the project and its accompanying website all but disappeared from the face of the earth.

During this time it was unclear whether or not Nintendo and/or Rockstar Games had presented Provinciano with a lawsuit, or he had simply moved his efforts towards the Retro City Rampage we know and love today. Either way, Provinciano seems to have kept a good portion of his prototype's code due to its recent inclusion as a playable extra in the PC and Wii versions of the game.

What makes this addition even more interesting is Provinciano's recent upload to YouTube. His newly uploaded video details the ins and outs of how he managed to compress such a huge game into vintage hardware given the many limitations presented.

But where it gets even more interesting is the many references to how he coded this prototype ROM, the emulator he built for Retro City Rampage to play it, and of course converting the music over into a suitable format. Although he rarely mentions the Nintendo NES in his video, it's rather clear that Provinciano has created a working 8-bit version of Grandtheftendo - which in theory should be playable on the original NES hardware.

It wouldn't surprise us if over the next few days somebody manages to extract the Nintendo NES ROM from Retro City Rampage's code and have it booted up on the original hardware. Something that can easily be done now thanks to the likes of the Everdrive N8 and Powerpak flash cartridges.

Update: There is still very much speculation as to whether or not this is indeed a Nintendo NES version, or nothing more than a replica intended to only run in Retro City Rampage. Frank Cifaldi of The Lost Levels recently posted on NintendoAge his thoughts as to why this is unlikely to hit a Nintendo NES any time soon.

I think what a lot of you don't realize is that this game CAN NOT WORK ON A NES. I hope this prototype ROM, and the making-of video, will make that clear. It is made to look like an authentic NES game, but a lot of what it does just wouldn't work, no matter how hard someone were to work on "porting" the game.

There was never a full game on the NES, there were prototypes that were proof-of-concept demos to push the NES and see what it was capable of doing.

The making of video for the original was amazing. One of the best videos on making a video game I've ever seen. The recreated ROM actually releases for free with the STEAM and WiiWare versions.
