'Impossible' horror game rises from the grave 25 years after it was canceled

Resident Evil is one of gaming's most iconic franchises, and giving us an early Christmas present, one previously canceled entry into the horror series has emerged online over 25 years after it was canceled. Its unexpected return from the dead has left many fans equally stunned and amazed.

There are so many games releasing each year that it's almost impossible for anyone to play them all, and that's discounting the hundreds, if not thousands, of titles you likely already have in your backlog.

Sometimes this can leave you with choice paralysis, where you end up playing nothing simply because you've got so many options to select from. Still, one unlikely Resident Evil port could emerge as the perfect thing to break that deadlock if you're someone who's fascinated by the medium's history.

As reported by VGC, a 'near-complete' version of a cancelled 2000 Nintendo Game Boy Color version of the OG Resident Evil, estimated to have around 98% of the content preserved, has surfaced online.

Our first big Christmas update is with an amazing recovery of the final build of Resident Evil on Gameboy Color. Hotgen's impressive conversion that got canned. This is much closer to completion, and seems completable too. Lots to discover!https://t.co/PqnSERyZuP pic.twitter.com/u2sPODb7dS

You might not have even known that this was something that could have existed, as it was canned just before its release. This was despite achieving impressive optimization for a 'downgrade' that was considered to be impossible, and the result that we see today is nothing short of remarkable.

The original Resident Evil originally released on the PlayStation and Sega Saturn, which both benefitted from the far larger size potential of CDs compared to cartridges. There were also the general performance enhancements that both consoles had over Nintendo's flagship handheld.

London-based studio HotGen was tasked with the seemingly impossible task, yet their work never saw the light of day — at least until now, that is.

Prototype ROMs have seemingly been floating around the internet for over a decade now, although the recent release is by far the most complete its ever been, and it's seemingly playable from start to finish in the state at which it was canceled.

The project was preserved and released by Games That Weren't, with assistant programmer Pete Frith providing the new build that you can play today.

It still has some issues, including unfinished cutscenes, wrong sprite colors, and 'incorrect' zombie animations, but this new version has the Tyrant enemy and the game's ending for the very first time, making it undeniably the definitive release.

As for the reason why it was canceled, Frith remembers that HotGen was told that the 'original creator' of Resident Evil didn't believe that the game was the right fit for the Game Boy, deeming Nintendo's console 'not worthy' of what quickly became one of the industry's most iconic releases.
