Ps1 Classic — Project Eris

When Sony released the PlayStation Classic in late 2018, it was met with a mixed reception.

However, because the device ran on an open-source Linux operating system, it wasn't long before the modding community cracked it open.

Project Eris emerged as the definitive custom firmware (CFW) for the PlayStation Classic. Unlike simple "jailbreak" scripts that merely added a few games, Project Eris was a complete overhaul of the system’s software, turning the plug-and-play box into a versatile retro-gaming powerhouse.

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.

The PlayStation Classic, released in 2018, was Sony’s micro-console homage to the original PS1. But with a disappointing game list, PAL versions running at 50Hz, and lackluster emulation, it left many fans cold.
