Classic Project Eris — Ps1

When modding a PlayStation Classic with Project Eris , users often refer to "PaPer-DJ" (often abbreviated as "PaPer") as a highly helpful resource for organizing and optimizing their builds.  Essential Resources from "PaPer-DJ" 

The developer PaPer-DJ maintains a comprehensive GitHub repository that acts as a "helpful paper" or directory for the PS Classic scene. It includes: 

Directory Structure: A clear breakdown of where to place files on your USB drive (e.g., USB:/project_eris/opt/retroarch/config/retroarch/cores for emulator cores).

Asset Paths: Specific locations for BIOS files (USB:/project_eris/opt/retroarch/system) and overlays/bezels.

Tools: Links to essential software for managing game libraries and metadata.  Key Setup Tips for Project Eris 

To ensure your Project Eris build runs smoothly, follow these community-standard practices: 

USB Formatting: Your initial install drive must be formatted as FAT32 and named SONY in all caps. Once the kernel is installed, you can switch to more stable formats like NTFS or exFAT via an OTG adapter.

Power Supply: Many startup issues (like the console shutting down or bypassing the mod) are caused by insufficient power. Using a power adapter that provides at least 5V/2A (10W) is recommended, as the front ports are severely underpowered.

Game Organization: If you have a large library (250+ games), the default carousel can become unstable. Use the Project Eris Desktop App to organize games into folders of fewer than 200 items each to maintain performance.

Automatic Metadata: Project Eris can automatically scrape box art and metadata for games dropped into the transfer folder by recognizing their unique disc signatures.

What is Project Eris?

Project Eris is a modding suite (often called a "hack" or "custom firmware") created by a developer known as acelovesicecream. It is the successor to an earlier popular hack called BleemSync.

Unlike hardware mods that require soldering or replacing chips, Project Eris is a software-only USB drive solution. It exploits a vulnerability in the PS1 Classic’s boot sequence, allowing the console to read modified files from a USB flash drive.

In simple terms: Project Eris replaces the stock interface, improves the emulation core, and allows you to add hundreds of your own PlayStation games, as well as titles from other retro consoles.

Step 1: Prepare the USB Drive

Download the latest Project Eris release from the official ModMyClassic GitHub. Use a tool like Rufus (Windows) or BalenaEtcher to format your USB drive to FAT32 and label it SONY. Do not use exFAT or NTFS for the initial setup.

The Best Cores to Install on Project Eris

While PS1 games are the star, Project Eris turns your console into a retro museum. Via the "RetroArch" menu (select + triangle), you can download cores for:

• SNES (Snes9x 2010): Play Chrono Trigger and Super Metroid perfectly.
• Genesis (Genesis Plus GX): Sonic 3 & Knuckles runs at 60fps.
• GBA (mGBA): Pokémon FireRed and The Legend of Zelda: Minish Cap.
• N64 (Mupen64Plus): Requires overclocking the PS1 Classic’s internal CPU, but Mario Kart 64 and F-Zero X work well.
• MAME (2003 Plus): Play arcade classics like The Simpsons and X-Men.

Pro Tip: To add these, connect your PS1 Classic to Wi-Fi (Settings > Network), enable "RetroArch Wi-Fi," then use the "Online Updater" inside RetroArch to download cores directly onto the console.

What is Project Eris?

Project Eris is a custom firmware and kernel mod for the PlayStation Classic. Developed by the legendary modder ModMyClassic (known for Hackchi on the NES/SNES Classic), Project Eris replaces the stock user interface and expands the console's capabilities.

Unlike simple "file copy" hacks, Project Eris permanently installs a custom kernel onto the PS1 Classic’s internal memory. This allows the console to run games from a USB drive without the limitations of the original file system (such as the infamous 240-title limit that plagued early mods).

Community Status (as of 2026)

Project Eris is mature and stable — last major update was 1.0 (2020), with small patches after. The developer (Team Shuffle / Cryo) moved on, but the mod remains the gold standard for PS Classic owners wanting a polished, permanent upgrade.

It’s widely supported on Reddit (r/PlaystationClassic), Discord, and YouTube tutorials (Patton Plays, MadLittlePixel, Restalgia).
