One Developer Turned Elden Ring Demake into a Nintendo 64 Reality

Action adventure fans with a soft spot for classic hardware now hold a genuine piece of Elden Ring in their hands. BoxingBruin, a game developer, spent years learning the ins and outs of Nintendo 64 programming before he and collaborator HelloNewman formed Team Zero Cool. Together they built Pandemonium, a dark-fantasy boss battle that feels right at home on the old console. The project started as an entry in the 2025 64brew Game Jam and arrived as a full playable demo in May 2026.

Players are pushed into a somewhat dramatic encounter with the Guardian of the Shackled Sun. This powerful warrior is the major obstacle to overcome, packing a punch with a wide range of strikes and animations that will require some serious timing and positioning, similar to the challenging bosses from FromSoftware’s back in the day. The character controller is rather snappy, handling all of the many animation stages with ease; in the meantime, the lock-on system puts the fight right in your face, and the incredibly detailed collision system ensures you know every single hit of the sword. It’s also quite cool how the sound effects correspond to the distance between you and your foe, and to top it all off, there’s this incredible original orchestral soundtrack rising in the background to really get you hyped up.

Graphics are all about maximizing the console’s capabilities without breaking the rules. Textures are the standard 64 x 64 pixels, but when combined with vertex colors, you get a really crisp degree of detail that could only be accomplished on this type of hardware. And just when you thought it couldn’t get much better, the 32-bit framebuffer sharpens the entire image, which many felt was unachievable at the time. He also incorporated some super-realistic cinematics with video-style cut sequences, and by scrolling textures across skinned meshes, we were able to add some subtle life to the landscapes, making you feel like you’re actually in the game. Every asset and piece of music was created from scratch, giving the entire thing a really coherent vibe, as if it were one of the late-era N64 titles you used to play.

The demo just works fine on the old Nintendo 64 consoles; all you have to do is load the ROM into a flash cart and you’re done. For computers, the Ares emulator is the sole way to run them, and it accurately reproduces the original performance and controls. Version 0.65 is currently available on the team’s GitHub page, allowing you to download it and get right into the boss fight.
